IPC: G11B7/005
Filed: 1993-04-30
Abstract: PURPOSE:To reproduce the information having the spatial frequency higher than the spot diameter of a read out light by reproducing the recorded information with a reproducing means in accordance with 1st or 2nd light receiving signal. CONSTITUTION:In the disk reproducing device 11, the optical disk 12 is rotationally driven by a spindle motor 13, and a pickup 14 is driven in the track direction by a carriage motor 15, then the recorded information of the optical disk 12 is read out and converted to signals SRF and outputted to a preamplifier part 16. The signals are amplified there and outputted to a decoder part 17, and also a focusing error signal SFE and a tracking error signal STE are produced and outputted to a servo part 18. By the decoder part 17, a signal from the read out area among the inputted signals SRF is separated by using the threshold corresponding to the signal level, then the separated signal SRF is converted to a binary signal, and further a frame synchronizing pattern is separated and subjected to EFM demodulation, then it is outputted to a D/A converter part 19. Thus, the information having the spatial frequency higher than the spot diameter of the read out light is reproduced.

Title: Photoresist baking method
Inventor: YAMAZAKI SHIYUUSUKE
IPC: G03F7/00
Filed: 1978-08-28
Abstract: PURPOSE:To intensify adhesion strength with film and increase the processing precision, by exposing and developing the photoresist, baking at low temperature, and then backing at high temperature. CONSTITUTION:An SiO2 film 2 is formed on a glass substrate 1, and a photoresist 4 is spread and dried, then exposed and developed. After baking at low temperature  for 20 minutes at 140 deg.C, the resist 4 is polymerized and crosslinked to increase the  thermal characteristics. Then, by baking at high temperature for 20 minutes at  200 deg.C, the adhesion strength with the film 2 is intensified. As a result, the amount  of side etching of the film 2 in the next etching process is limited to 2 to 3 times of  the thickness of the film 2. Thus, the film measuring more than about 1 mum in the thickness of the film 2 in particular may be processed at high precision.

IPC: F02D41/22
Filed: 1988-04-28
Abstract: PURPOSE:To prevent the overrich by an excessive amount of fuel injection by changing the maximum value of an amount of fuel injection in accordance with a trouble condition when a variable intake means causes a trouble. CONSTITUTION:A variable intake control valve 9 is driven opening and closing by a negative pressure actuator 10, and opening and closing a communication path 7 connecting two or more branching intake passages 2 to mutually communicate, a natural frequency of an intake system is changed in accordance with an operative condition of an engine 1. While a control unit 16 compares an intake air amount per one turn of the engine, based on a detection value of an air flow meter 14, with a preset value of the intake air amount when a throttle is fully opened in an opened or closed condition of the variable intake control valve 9. When the intake air amount, based on the detection value, not reaches the preset value, a some trouble is decided to be generated in the variable intake means, and by setting the preset air amount a little smaller, a fuel injection amount, set in accordance with the preset air amount, changes the guard value a little lower. In this way, the overrich can be prevented when the variable intake means is in trouble.

Title: Energy converter
Inventor: FURUYA CHOICHI
IPC: H02N3/00
Filed: 1988-04-28
Abstract: PURPOSE:To convert energies of pressure and temperature differences directly into electric energy by providing pressure or temperature difference of reactive gas at one and the other gas diffused electrodes. CONSTITUTION:Two opposing gas diffusing electrodes provide an operating area of 100cm<2> and a gap of 0.6mm between them. Electrolyte 5 of 20% aqueous sulfuric acid solution is circulated under pressure by a pump, a check valve is attached to the outlet of the electrolyte 5, and pressure is so controlled as to become larger by 0.1 atm than a high pressure side P1. Since a gas-diffusing electrode 1 has a water repelling porous layer having fine water repelling holes of 0.1mum or less, its hydraulic pressure resistance is high, the electrolyte is pressurized by the pressure P1 of a high pressure side gas chamber, and depressurized by the pressure P2 of a low pressure side gas chamber. Since the two electrodes 1 are opposed in parallel and an interval between a cathode and an anode can be set to 1mm or less, electrolyte resistance can be reduced.
