48-1962 - AIEE Standard for Potheads
1962 Edition, May 15, 1962 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This standard covers all types of indoor and outdoor potheads for alternating-current circuits (see Table 3 for voltage ratings). So-called through-type potheads are not within the scope of this Standard. Potheads and component parts shall be capable of withstanding the tests specified in this...

48-1948 - AIEE Standard for Potheads
1947 Edition, December 31, 1947 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

These standards cover all types of indoor and outdoor potheads for alternating-current circuits (See Table 4 for voltage ratings). Potheads and component parts shall be capable of withstanding the tests specified in these standards, when mounted for testing in accordance with arrangements...

ST 48:1995 - For Motion-Picture Film (16-mm) — Picture and Sound Contact Printing — Printed Areas
1995 Edition, May 10, 1995 - Society of Motion Picture and Television Engineers

This standard specifies the location and size of the printed picture and photographic sound track areas for both negative/positive and reversal contact printing operations. An opaque line should appear between picture and sound in the finished print. The dimensions given for picture-printed area...

Two New CMOS Consortia Worth Mentioning
Critical Link, LLC

There's some interesting news on the CMOS front that I wanted to share with you. This past May, in Europe, two different consortia began work on CMOS image sensor projects.

CMOS LDO Regulators for Portable Devices (.pdf)
ROHM Semiconductor USA, LLC

ROHM CMOS LDO (low drop-out) regulators are tailored for use in portable devices such as PDAs, mobile phones, digital cameras and camcorders. Lower in cost and small in packaging, ROHM CMOS LDOs offer designers a superior alternative to PWM regulators in many point-of-load...

CMOS Cameras Rise to Speed Challenge
PCO AG

Advances in CMOS image-sensor technology are making it possible for a new breed of highspeed cameras to capture events previously impossible to image by conventional CCD cameras. Improvements in chip design and manufacturing have enabled CMOS cameras to become a...

Pin-Compatible CMOS Upgrades to Bipolar LDOs
Microchip Technology, Inc.

Bipolar low dropout regulators (LDOs) have become common place in a variety of portable applications, such as cell phones, pagers and PDAs. Their popularity stems from small packaging, high output current capability and precision output voltage specifications. However, the bipolar process...

CMOS Isolators for Home Appliance Motor Control
Silicon Labs

The home appliance market uses three-phase, pulse-width-modulated (PWM) motors in a number of end applications including air conditioners, washers, dryers and garage door openers. Many of these applications require variable speed and/or torque, and the controllers that provide this...

ASTM E3265-21 - Standard Guide for Evaluating Water-Miscible Metalworking Fluid Foaming Tendency
April 1, 2021 - ASTM International

1.1Â This guide provides an overview of foaming tendency evaluation protocols and their appropriate use. 1.2Â ASTM Test Methods D3519 and D3601 were withdrawn in 2013. Although each method had some utility, neither method reliably predicted in-use foaming tendency. Since Test Methods D3519 and...

ASTM F19-21 - Standard Test Method for Tension and Vacuum Testing Metallized Ceramic Seals
April 1, 2021 - ASTM International

1.1Â This test method covers procedures for conducting tension and vacuum tests on metal-ceramic seals to determine the bond strength of brazed, metallized ceramics. 1.2Â The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3Â...
