Patent JP-H03149514-A (JP)
Title: Optical scanner
Inventor: YAMAZAKI TATSUYA
IPC: B41J2/44
Filed: 1989-11-07
Abstract: PURPOSE:To make the radius of the circumscribed circle of a rotary polygon mirror small and to improve the image forming performance by using an optical element which is combined with a beam splitter as the lens which is closest to the rotary polygon mirror and arranging a light source off the same plane with the main scanning plane of a light beam. CONSTITUTION:Reflected light which is split by the beam splitter 14a is reflected and deflected by the rotary polygon mirror 17 without any loss of the quantity of light to make a scan, and the light is made incident on a BS lens 14 again. Further, the angle of deflection of laser light and the transmissivity of the BS lens 14 are stored previously for the beam splitter function of the BS lens 14 so as to obtain desired reflection and transmission characteristics and while the stored data and the image signal of a photodetector 16 are contrasted with each other, intensity modulation is imposed on the laser light. Consequently, the angles of incidence and projection of the laser light on the rotary polygon mirror 17 are made maximum and while the circumscribed circle diameter of the rotary polygon mirror 17 is decreased, image formation by an ftheta lens becomes symmetrical, so the image forming performance can be corrected effectively.

Title: Inspection method for traction control
Inventor: SHIBAYAMA TAKAO
IPC: G01M17/007
Filed: 1992-10-26
Abstract: PURPOSE:To exactly judge the properness of traction control regardless of pedaling depth of an accellerator by correcting the reference value for judging the properness according to the maximum speed of roller for driving wheels during the deceleration of the roller for following wheels. CONSTITUTION:A vehicle is run putting for driving wheels (front wheels) and following wheels (rear wheels) on each roller. When the revolution speed of the roller or the wheels increased to the maximum speed Vs, the follwing wheels are decelerated. Then, a revolution speed difference is caused between the driving wheels and the following wheels, which is judged to be occurrence of slip at the driving wheels and a traction control moves to decelerate the revolution speed V1 of the driving wheels in accordance with the deceleration to the revolution speed V2 of the following wheels. If the accelerator pedal is pushed strongly, then the deceleration rate of the driving wheels significantly overshoots and it shifts from a reference line. Thus, the maximum speed V1 max of the driving wheels during the reference value is corrected basing on the shift DELTAV from the reference line and the properness of the traction control is judged.

Abstract: PROBLEM TO BE SOLVED: To form a surface light source device capable of effectively utilizing light from a light source and suppressing the generation of a bright line on an incident part by forming a specific roughened surface area on a translucent substrate and specifying the plus point average roughness of an incident light scattering roughened surface part. SOLUTION: Reflection faces 3 consisting of a metallic layer such as silver or aluminium are formed on end faces other than the incident light face 4 and outgoing light face 5 of the translucent substrate 2 and a rear face and a roughened surface part 7 is formed on at least one of the outgoing light face 4 and its opposite side face (rear face). A front face or a rear face close to the end face (incident face 4) of the substrate 2 provided with a primary light source 1 is formed as specific structure. Namely a range of length (distance) equal to the thickness of the substrate 2 from the primary light source side end face of the substrate 2 is set up to a roughened surface area 9 of 0.5μm<=Rz<2μ (provided that Rz is plus point average roughness).  Since the area 9 is formed extremely near to the light source 1, incident light is scattered immediately after its incidence and the generation of a bright line can be prevented.

Title: Register access system

IPC: G06F7/00
Filed: 1988-11-18
Abstract: PURPOSE:To rewrite all registers just with a single writing action by designating the information on a register to be invalidated out of those registers included in the same address with use of some bits of the write data. CONSTITUTION:The address common to I/O registers A - D functions to set an address decoding line 11 at 1 in a write state. When the data is written into the register A, only the register selection signal 21 of the register A is set at 1 among those register selection signals corresponding to the registers A - D as long as the prescribed data is written into the register A. Then the register selection signals 21 - 24 undergo the AND with the data strobe signals via AND gates 70 - 73. Then only the write signal 15 of the register A is validated, and the data is written into the register A only. Thus it is possible to rewrite all registers with a single writing action even though plural addresses are allocated to the same address.
