Title: Manufacture of semiconductor device
Inventor: SAKAMOTO HIROICHI
IPC: H01L21/338
Filed: 1989-12-15
Abstract: PURPOSE:To reduce a gate resistance and a gate length by a method wherein, after a first spacer is etched to form an aperture, a second spacer layer is built up to reduce the width of the aperture of the spacer layer further. CONSTITUTION:After a spacer layer 3 is etched to form an aperture, a second spacer layer 31 which has a lower etching rate than the first spacer layer 3 is further built up to reduce the width of the aperture of the spacer layer further. With this process, the spacer part aperture width is reduced when gate metal is deposited so as to form a T-shaped gate 61 having a reduced gate length Lg and a reduced gate resistance. Thus, by forming the T-shaped gate electrode 61 having the reduced aperture width, the gate resistance can be reduced and the gate length of the T-shaped gate can be reduced.

Title: Controller for engine
Inventor: AIGA SHOICHI
IPC: H02J7/16
Filed: 1990-11-28
Abstract: PURPOSE:To reduce a variation in torque by suppressing control execution state of one or both of feedback control means and load control means when the magnitude of an outer load is altered during execution of feedback control of an engine combustion state. CONSTITUTION:When altering condition (low control condition) of a target voltage of an alternator 8 is satisfied during feedback control of an air/fuel ratio, a high-low value is set as a low control target value.

Filed: 1987-12-25
Abstract: PURPOSE:To attain reception and reproduction of a NTSC signal by providing a means applying logic processings such as addition of a new signal, time axis expansion and compression to the NTSC picture signal. CONSTITUTION:A high definition television signal is reproduced into a high definition pattern 31 with 1125 scanning lines and aspect ratio of m:3 (m>4) by the reception and decoding at a receiver 1. At first an ineffective signal is added to the existing NTSC signal for each scanning line. Thus, both ends or one of left and right ends go to a black level. Then an ineffective signal by 600 scanning lines (1125-525) is added to the vertical blanking period and one end of upper/lower goes to a black level. The NTSC (National Television System Comittee) signal can be received by using a receiver 2 reproducing part of the pattern as an ineffective pattern in this way. Moreover, the addition signal is subject to time axis expansion and compression to reproduce the NTSC signal on the entire high definition television pattern whose aspect ratio is m:3.

Title: Positioning device for camera
Inventor: OZEKI YOSHIYUKI
IPC: G02B7/09
Filed: 1994-12-28
Abstract: PURPOSE: To improve the detent point precision of the positioning device for the camera which uses a stepping motor as a driving source and detains a position member by a detent mechanism. CONSTITUTION: When a motor pinion 4a rotates counterclockwise, a driving ring 2 rotates counterclockwise through a two-stage gear 5 and a lens driving ring 3 is driven to rotate clockwise. The rotation of the lens driving ring 3 is transmitted to a pinion 12b in the same shape with the motor pinion 4a rotating together with a ratchet gear in one body through a rack 3a and a two-stage gear 11 in the same shape with the two-stage gear 5, so the step rotation angle of the ratchet gear 12a becomes equal to the step rotational angle of the motor pinion 4a. Therefore, the gear pitch of the ratchet gear 12a can be made large and deterioration in detent point precision due to a component error and other factors can be prevented.
