Patent JP-H06177748-A (JP)
Title: Semiconductor circuit
Inventor: KITAMURA NOBUAKI
IPC: H03K19/0175
Filed: 1992-12-10
Abstract: PURPOSE:To reduce vibration noise even under a low voltage power supply environment by logically driving an output with an output level of a CMOS logic output circuit and suppressing overshoot and ringing of an output voltage by a parallel addition circuit. CONSTITUTION:It is possible to drive logically an output to be driven logically to an H or an L level nearly equal to a level of a power supply depending on an output voltage range of a CMOS logic output circuit 1, but a transient phenomenon is liable to be caused due to a parasitic inductance of an external wire connecting to the output and overshoot or ringing takes place without circuit modification. In avoid it, a parallel addition circuit 2 is added newly and fluctuation in an output voltage is suppressed by voltage control of a source follower output thereby. That is, when an output potential exceeds a specified H level, the output potential is forcibly reduced to the specified H level by a PMOS TR P2 acted at the low level power supply potential.

IPC: H04N1/053
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce the positional deviation of a beam spot on an image surface caused by the relative wavelength difference of a light beam from each light source by simple and inexpensive constitution by making the refraction amount of the transmitted light beam in a scanning direction differ in accordance with the oscillation wavelength of the light source and adjusting the incident timing of plural light beams on a scanning start detection sensor.

The prism 25 is arranged so that its main cross section may be parallel with a main scanning cross section and incident light may be refracted in a direction opposite to a scanning advancing direction. The light beams of design wavelength and long wavelength are simultaneously made incident on the sensor 20 by the prism 25. Therefore, the positional deviation of the beam spot on the image surface caused by the relative wavelength difference of each light source is reduced without making a scanning optical system a chromatic aberration compensation optical system.

Title: Auxiliary steering device for vehicle
Inventor: MORI HIROSHI
IPC: B62D7/14
Filed: 1988-12-29
Abstract: PURPOSE:To improve the movement performance of a vehicle due to the auxiliary steering by forming an insensitive band having an auxiliary steering angle of 0 deg., in the vicinity of the neutral point free from the steering operation. CONSTITUTION:The insensitive band (alpha) having an auxiliary steering angle of 0 deg. is formed in the vicinity of the neutral point having a turn angle of theta=0 deg. free from steering operation. The insensitive band (alpha) is set within a set turning angle (theta) which is varied by the external turbulence, etc., supplied from a road surface during the right angle traveling free from the advance direction change, i.e., within a range of + or -15 deg.. The variation rate of the auxiliary steering angle deltagammafor the turning angle theta of a steering wheel is set smaller in the less turning angle theta region of the steering wheel and set larger as the turning angle thetaincreases. With this constitution, even if the turning angle theta of the steering wheel deflects slightly from 0 deg. by the external tubulence supplied from the road surface, the auxiliary steering angle is not provided because of the setting within the region of the insensitive band (alpha), and the straight advance performance is not deteriorated. Thus, the movement improvement effect due to the auxiliary steering can be improved.

Title: Semiconductor device
Inventor: OGATA TOSHIAKI
IPC: H01L23/52
Filed: 1990-11-29
Abstract: PURPOSE:To enable a semiconductor device provided with a ROM to be shortened in manufacturing term by a method wherein a transistor is selectively changed in threshold voltage in a process after a gate wiring is formed. CONSTITUTION:As P-type impurity ions are implanted into polysilicon films 3 and 4 which partially constitute a gate wiring at the time when a P-type diffusion layer 2 is formed, the polysilicon films 3 and 4 are of P-type, but they display an N-type or an intrinsic type as impurities contained in the polysilicon films are absorbed into a silicide film depending on the amount of impurity ions out of the conditions under which silicide films 5 and 6 are formed through a silicide method or the like. Taking advantage of the above phenomenon, a thermal process is selectively added to the manufacturing processes of some of transistors, whereby transistors formed through a thermal- process added manufacturing process can be selectively lessened in threshold voltage to form ROMs. By this setup, a manufacturing term from the formation of data to the completion of a product can be remarkably lessened.

Title: Optical disk substrate and die for forming the substrate
Inventor: SHIBATA YASUMASA
IPC: G11B7/24047
Filed: 1993-12-27
Abstract: PURPOSE:To obtain an optical disk substrate and its forming die from which a stamper and the formed substrate are surely released and the substrate is easily released. CONSTITUTION:The cavity of a die is formed so that a vertical plane 32 on the information plane side and first and second tapered planes 35 and 36 are formed on the outer periphery surface 30 of a substrate. When the die is opened after forming, the first tapered plane 35 of the substrate is made to abut on the first taper forming plane as the undercut of the cavity, hence the movement toward the stamper side is controlled, and the substrate and stamper are surely released from the die. Since the crossline 42 of the periphery 30 with the information plane 31 is positioned outside the crossline with a mirror plane 33, the substrate is surely released from the die without moving the substrate by its thickness.
