Title: Porous fabric elastomer and preparation thereof
Inventor: NATORI HITOSHI
IPC: D03D15/567
Filed: 1989-03-27
Abstract: PURPOSE:To enhance cushioning capacity and to hold elastic strength over a long period of time by filling the inner and outer surfaces of a hollow reticulated fabric with a reinforcing elastomer such as a foam, latex or a thermoplastic elastomer to constitute an integrally bonded structure and boring piercing holes at the position corresponding to a bent space elastic part. CONSTITUTION:A hollow reticulated fabric 1 is prepared by applying heat treatment to a fabric woven using a synthetic resin fiber low in heat shrinkability and a synthetic resin fiber high in heat shrinkability as warp yarn and weft yarn. Upper and lower flat woven surfaces 2a, 2b are constituted of the fiber high in heat shrinkability and the fiber low in heat shrinkability are bent in a loop wavy form between the upper lower woven surfaces 2a, 2b to form space elastic parts 3 having gaps. After a liquid reinforcing elastic material such as a foamable material, latex or a thermoplastic elastomer is injected in the hollow reticulated fabric 1, said elastic material is foamed and cured to prepare a fabric elastomer wherein the reinforcing elastomer 4 is integrally bonded to the inner and outer surfaces of the hollow reticulated fabric 1. Circular piercing holes are horizontally bored in a large number of the space elastic parts 3 parallelly arranged of the fabric elastomer in parallel respectively to obtain a porous fabric elastomer 5 having a large number of piercing holes.

Title: Manufacture of cmos semiconductor device
Inventor: YAMAMOTO TADASHI
IPC: H01L27/092
Filed: 1987-03-27
Abstract: PURPOSE:To prevent the surface of a first conductivity type semiconductor region from being etched by forming a first film on whole first and second conductivity type semiconductor regions, further selectively laminating a second film on the first film on the first conductivity type semiconductor region, and then etching it with the second film as a mask. CONSTITUTION:After a field oxide film 103 is formed as an element separating region on a substrate 101 and an n-well layer 102, a photoresist pattern 118 is laminated on a CVD-SiO2 film 117 on part of the film 103 and an n-well layer surrounded by the film 103. With the pattern 118 as a mask it is etched by RIE, etched back in the degree of the thickness of the film 117 to allow a wall 119 of a CVD-SiO2 film to remain in a self-aligning manner on the sidewall of a gate oxide film 106 to expose the surfaces of low concentration n<-> type diffused layers 1141, 1142. Thus, the film 117 formed on the layers 115, 116 is not etched. Thus, it can prevent the resistance generated by the damage of the layers 115, 116 by etching from increasing and an element speed from decreasing due to it.

Title: Steering controller
Inventor: SUGITANI NOBUYOSHI
IPC: B62D6/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To control return speed of a steering wheel according to feed speed of the steering wheel by calculating return speed according to feed speed of the steering wheel and performing a driving control so as to be calculated return speed. SOLUTION: When a feed steering is performed from a steering angle θ1 to θ2 during time t1, the average feed speed av θ' of a steering wheel is determined as av θ'=(θ2-θ1)/t1 while this feed steering is performed (S 110). When a return steering is judged to be started (S 112), the average return speed av θ' rm of the steering wheel in the return steering is calculated based on the average feed speed av θ' calculated. Based on the value of the average return speed av θ' rm calculated, a function F (θ) of a steering angle θ and the return speed θ' rm at the time of the return steering is selected (S 114). Continuously, the return control of the steering wheel is performed so as to be the return speed stipulated by the F (θ).

Title: Fixing device and image forming device
Inventor: HANEDA SATORU
IPC: G03G15/20
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To quickly start a control of preventing a low-temperature fixation offset at the time of starting a printing operation by controlling so that fixation may be executed after the surface temperature of a hot-wire fixation rotary member reaches the appropriate temperature for fixation and after heating for a prescribed time at the appropriate temperature for fixation. SOLUTION: In order to thoroughly supply a power for quickly increasing the temperature up to the appropriate temperature for fixation, a processing operation is not executed at an early stage(prior to a printing operation), the power is distributed to the fixing device 17 in a concentrated state, and after the temperature of the hot-wire fixing roller 17a rises up to the appropriate temperature for fixation, the temperature is controlled for the prescribed time, but the heat is emitted from the surface of the roller 17a, then, even in the case of turning a halogen lamp 171g off, the occurrence of overshooting is prevented. This is because the heat on the surface of the roller 17a is diffused inside and the surface temperature immediately drops.  Thus, even in the case of executing the on - off control, or a phase control, etc., just after the temperature rises up to the appropriate temperature for fixation, temperature ripples become less.

Filed: 1987-03-25
Abstract: PURPOSE:To check the short circuit of an input circuit without considering a delay time by outputting the output of an AND gate which inputs the outputs of adjacent delay means through an OR circuit and a transfer gate. CONSTITUTION:When signals which rise to a high level for a necessary time are inputted from terminals I11-I13 by an input circuit equipped with an input terminal, a delay means I11 and D11-I13 and D13, etc., the outputs of the means D11-D13 go up to the high level without overlapping with one another in terms of time. For the purpose, the outputs of adjacent means D11-D13 are applied to AND gates 12 and 13, whose outputs are outputted to an output terminal O11 through the OR circuit 14 and the transfer gate 16 which is opened with a test signal, so that the output at the terminal O11 goes up to the high level only when adjacent delay means D11-D13 short-circuit which each other. Consequently, the short circuit of the input circuit is easily and securely checked without considering the delay time.

Title: Electric-motor controller
Inventor: TANABE MASAHIKO
IPC: H02P21/22
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To detect the abnormality of a PWM generating circuit under the state, in which an electric motor is not driven, and to inform a driver of abnormality before the electric motor is driven in a controller using the electric motor such as an electric power steering controller. SOLUTION: When the non-driving of an electric motor on steering torque is decided, a current value for monitoring abnormality, where a value, where the electric motor is not rotated even at the time of conduction, is set, is output to a PWM generating circuit 52 as a target driving current value iMF. Since a PWM signal PWMF corresponding to the target driving current value iMF is generated in the PWM generating circuit 52, the PWM signal PWMF corresponding to the current value for monitoring abnormality is generated even when the electric motor is not driven.  Accordingly, a driver is informed of the generation of abnormality in the PWM generating circuit 52 when the PWM signal PWMF is not generated from the PWM generating circuit 52 for a fixed period and is not generated even after a fixed time passes under the state, in which the electric motor is not driven, in the control circuit 34.

Title: Mark-position detecting method in electric-charged-particle-beam-exposure device
Inventor: NIIJIMA HIRONOBU
IPC: H01J37/305
Filed: 1986-03-31
Abstract: PURPOSE:To swiftly detect a mark position, by detecting the mark position while a stage being consecutively moved at a maximum speed satisfying three specific conditions. CONSTITUTION:While a mark position being detected, a stage is consecutively moved at a speed, which is below a stage-allowable one. The distance, in which the mark is moved while the position of one mark being detected, is below the length between marks in the stage-moving direction. The distance, in which the mark is moved while the beams being scanned to detect the position of one mark, is below the length of beam deflection in the stage-moving direction. The maximum value of the stage-moving speed satisfying these three conditions is computed in a stage-speed operational circuit 36, to be supplied to a stage controlling circuit 34, so that the stage 15 is consecutively moved. Hence, the mark position can be determined at a high speed.
