IPC: G01G21/23
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To provide the electronic balance which can implement a method for putting a sample pan away from a pan receiver and then gently mounting it on the pan receiver with simple structure and does not require much manufacture cost. SOLUTION: A sample to be measured is placed on the sample pan, which is set on pan reception rods 14 provided at three places on a pan support spring 7 extending in three ways. When a motor 12 is driven with the set button (not shown in the figure) of a device pressed, a cam 11 rotates through a worm gear 10 and a driving lever 13 is drawn by a tension spring 9 to rotate along the diameter of the cam 11. The pan support spring 7, therefore, rotates to bend and move up and down in conformity with the shape of spring up/down projections 8 provided on the reverse of the pan support spring 7. Through the bending, the pan reception rods 14 move up and down. When the cam 11 makes a half rotation, the pan support spring 7 bends downward, the pan reception rod 14 moves down, and the sample pan is mounted on the pan receiver 2, so that its load is sensed by a weight measuring system.

Title: Lockup release control device for torque converter
Inventor: SAKAI HIROMASA
IPC: F16H59/36
Filed: 1994-12-12
Abstract: PURPOSE: To provide control through which release of lockup of a converter is executed without a shock and with response as high as possible under any transmission torque. CONSTITUTION: When it is decided by a controller 5 based on a throttle opening TVO and a car speed VSP that a torque converter is in a lockup release area, a differential pressure PA-PR between the front and the rear of a clutch 2 is reduced through a control valve 3 by reduction of a signal pressure PS due to the decrease in a duty D, lockup of a torque converter 1 is released through release of a clutch 2. In the release, the differential pressure between the front and the rear is set to an initial difference pressure right before the clutch 2 is slid according to input torque during discrimination. Thereafter, after a lapse of a specified time, the differential pressure is gradually decreased from the initial differential pressure to 0.  The initial differential pressure causes release of lockup to a limit with high response within a range wide enough to prevent the occurrence of a shock.

Title: Solid-state image sensing element and manufacture thereof
Inventor: SUZUKI HIROMI
IPC: H04N5/335
Filed: 1992-10-20
Abstract: PURPOSE:To reduce smear and optical black false signal and prevent the generation of metallic spike by forming a metallic film constituting a light-shielding film by using a metallic material to suppress the generation of silicon nodule and forming a metallic film constituting a wiring film by using a metal to suppress generation of metallic. spike. CONSTITUTION:An aluminum film 9 forming a light-shielding film contains 0-0.5wt.% silicon. An aluminum film 10 forming a wiring film contains 0.5-1.2wt.% silicon. The film 9 has a low silicon content, so it is hard to generate silicon nodules. On the other hand, the film 10 has a high silicon content, so it is hard to generate aluminum spikes. Therefore, any smear and optical black false signal due to the silicon nodules of the light-shielding film and also the aluminum spikes can be reduced and prevented from being generated on the wiring film in a peripheral circuit as well.
