Patent JP-H1151089-A (JP)
Title: Electromagnetic coupling and braking device
Inventor: KOBAYASHI RYOJI
IPC: F16D27/112
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To restrain the generation level of shock noise and chattering by laminating an armature divided and formed into a two layer structure, and a cushion member between the two layers. SOLUTION: As a cushion member 15 between a first armature 14a and a second armature 14b of an armature 13, a donut-shaped spring washer waved in the circumferential direction or a donut-shaped elastic body made of rubber or the like is used. When a magnetizing coil 11 is released from the exitation state, the armature 13 attracted to a stator 12 is released and moved to the direction of a rotary plate 22 by a pressing spring 17, then an armature 14b is brought into contact with a rotary element 22 and the reaction force is transmitted to an armature 14a through the cusion member 15, whereby the armatures 14a, 14b are brought into close contact with each other, and the rotary plate 22 is pressed by the spring 17, resulting in stoppage of a hub. Since the light weight armature 14b is first brought into contact with the rotary plate 22 at the time of release, the shock is made small, and though the armatures 14a, 14b are brought into contact with each other thereafter, no substantial shock noise is generated.

Title: Developer for photosensitive polyimide precursor
Inventor: HIRABAYASHI NOBUO
IPC: G03F7/32
Filed: 1992-07-17
Abstract: PURPOSE:To easily and finely pattern a polyimide film by specifying the ratio of the liq. mixture of N-methyl-2-pyrrolidone, xylene, dimethylformamide and water to the dimethylformamide. CONSTITUTION:Dimethylformamide(DMF) is mixed by 5-40wt.% into a liq. mixture. In this case, a developer lacking in even one of the compds. or contg. <5wt.% DMF is reduced in the solubility and permeability to a photosensitive polyimide precursor film, the solubility and permeability are excessive when DMF exceeds 40wt.%, and dissolution is hardly controlled. The unsensitized part 14 of the photosensitive polyimide precursor 10 of the substrate 12 is dissolved by using the developer, and the dissolved part is formed after the lapse of a specified time. The patterned photosensitive polyimide precursor film 10 is then cured to obtain a polyimide film.

IPC: F04B49/06
Filed: 1984-10-12
Abstract: PURPOSE:To simplify the arrangement of a pipe line for controlling a shut-off valve disposed in a bypass-passage inorder to control the capacity of a compressor, and to simplify the control of the latter, by stopping once the operation of the compressor upon change-over from the high capacity operation of the compressor to the low capacity operation of the same. CONSTITUTION:In a bypass passage 24 there is disposed an opening and closing mechanism 20 for opening and closing the bypass passage 24l to change over the operation of a compressor between its high capacity operation and its low capacity operation. A shut-off valve 21 in this opening and closing mechanism 20 is applied with the pressure in a high pressure introduction pipe 23, and is controlled by a solenoid valve 30 which is closed upon change-over between the high capacity operation to the low capacity operation. Further, the compressor itself is once stopped with the use of a delay circuit to reduce the pressure differential across the compressor. Due to the reduction in the pressure differential the opening operation of the shut-off valve 21 may be made by the recovery force of a spring, thereby it is possible to eliminate a low pressure introducing pipe line, etc.

Title: Photoelectric converter
Inventor: TAKAHASHI HIDEKAZU
IPC: H04N5/335
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To attain high sensitivity processing of the photoelectric conversion characteristic by providing a floating gate amplifier to a picture element section and controlling the floating gate with capacitive coupling so as to control reset noise. SOLUTION: Electron-hole pairs are generated in a depletion layer 2 by an incident light hν transmitted through a photo gate 3 of a poly silicon electrode structure, and electrons are stored on a Si border in a depletion layer 2 under the photo gate 3 and positive holes are discharged to a p-well 1 by an electric field applied to the depletion layer 2 resulting from a control pulse ϕPG of a high level applied to the gate 3. When the storage period is finished, a transfer MOS switch is switched on to transfer the stored charge under a floating gate 8. When the charge is transferred under the floating gate 8, the potential of the floating gate 8 is changed through capacitive coupling and its potential change is outputted externally through source follower action.  Thus, the photoelectric conversion characteristic with excellent linearity and high sensitivity is obtained in a nondestructive way.

Title: Abnormality detector for software
Inventor: OKADA YASUSHI
IPC: G06F11/16
Filed: 1990-08-14
Abstract: PURPOSE:To surely detect malfunction by judging the coincidence of a current task identification(ID) number with all execution scheduled-task ID numbers and applying a timer reset signal to a timer. CONSTITUTION:A comparing/judging circuit 104 sequentially compares a current task ID number extracted from an input task storing circuit 102 at the time of executing the task with an execution scheduledtask ID number. At the time of judging the coincidence with the current task ID number with all execution scheduled-task ID numbers, a timer reset signal is generated and applied to the timer 101. Since time-up is not generated in the timer 101 when the software is normally operated, an abnormality detection signal is not outputted, but when the execution scheduled task ID number exists, the timer 101 is not reset, time-up is generated and abnormality is detected. Thus the abnormality detection of the software can surely be executed.

Filed: 1996-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head and a manufacturing method therefor, realizing recording/reproduction with a narrower track and a high recording density. SOLUTION: The recording track width WW corresponds to the length of a magnetic gap G formed between an upper core 34 and a lower core 22/an intermediate core 24.

Even if the position or width of the MR layered film 44 changes when being produced, the reproduction track width WR shows little changes. The recording track width WW and the reproduction track width WR are defined by a width of a flat portion at the top of a raised portion 12.
