Filed: 1993-04-15
Abstract: PURPOSE:To decrease the amt. of silver sludge without deteriorating a preservable property by incorporating sulfurous acid ions within a range of specific ratios into the material mentioned above and incorporating a cyclodextrin compd. thereon. CONSTITUTION:This photosensitive material contains the sulfurous acid ions within the 0.1 to 0.43mol/l liter liquid to be used and con-tains the cyclodextrin compd. The amt. of replenishing for development at the time of continuous processing by using an automatic developing machine is <=100ml/m<2>. The sulfurous acid ions refer to sulfate added as an antioxidant of a development main agent. The stability of the developing main agent increases with an increase in the amt. of addition. The amt. of the silver sludge to be generated increases drastically and the deterioration of the film at the time of development processing increases significantly when the amt. of the sulfurous acid ions to be added attains 0.43mol/l liter liquid to be used. The use of the liquid as a developer is no longer possible in such a case. The developability is drastically deteriorated and the liquid is no longer usable as the developer if the amt. of the sulfurous acid ions to be added increases 0.1mol/l liter liquid to be used.

Title: Controller for engine
Inventor: IWANO HIROSHI
IPC: F02D41/14
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To precisely accomplish torque required by a driver. SOLUTION: In this controller for an engine 1, an intake air quantity is controlled by means of a throttle valve 5 driven to be opened/closed independently of an accelerator pedal operation by a driver. In this case, a controller 16 compounds an accelerator opening operated by the driver and an intake quantity required for stabilizing the number of revolutions in an idle time together so as to find a required total opening area of the throttle valve 5. On the basis of an opening area found by normalizing the required total opening area, a target throttle valve opening is found, and the throttle valve 5 is driven so as to be opened/closed via a throttle valve driving device 6.  In this way, no error due to fluctuation in the number of engine revolutions is generated in a computing process, so that the intake quantity required by the driver and the intake quantity required from idle stability can be accomplished with high precision over the whole number of revolutions.

Title: Circuit board
IPC: H05K1/03
Filed: 1992-03-13
Abstract: PURPOSE:To improve the adhesion between a metal layer and a prepreg by laminating them with a low-temperature-plasma-processed tetrafluoroethylene- hexafluoropropylene copolymer (FEP) layer in-between. CONSTITUTION:An inner circuit board is so structured that a prepreg 1 and a patterned metal layer 3 are laminated with a low-temperature-plasma- processed FEP layer 2 in-between. Outer layer material 4, composed of a metal foil, is formed on and integrated with both sides of the inner circuit board with a low-temperature-plasma-processed FEP layer 5 in-between. In case a FEP layer 5 with its either side only low-temperature-plasma-processed is used, it is placed such that the processed face will face the inner circuit board. Since a FEP sheet is placed in-between in the lamination of a prepreg and a metal layer or in the lamination of an inner circuit board and outer layer material, these layers are firmly joined.

Title: Output circuit device
Inventor: KURIHARA MICHIO
IPC: G06F1/32
Filed: 1982-05-27
Abstract: PURPOSE:To avoid a simultaneous ON state of both of a P channel transistor TR and an N channel TR and to prevent a throgh current, by shifting the phase of input between the P and N channel TRs within a buffer circuit. CONSTITUTION:A TR25 is changed to ON from OFF when the voltage of an input terminal IN drops down to VP25 (threshold voltage of TR25) from the power supply voltage VDD (1). In this case, a TR27 is turned off since the G-S voltage is less than the voltage VP27. Therefore a point D has a rise from the voltage VSS owing to the ON state of the TR25. When the voltage of the terminal IN drops less than [VDD-¦VP25+VP27¦], the TR27 is turned on. Then a point E has a rise from the voltage VSS (2). A TR26 is changed to ON from OFF when the voltage of the terminal IN rises up to the voltage VN26 from the voltage VSS. Then the point E has a fall from the voltage VDD (3). When the voltage of the terminal IN exceeds [VSS+¦VN26+VN28¦], a TR28 is turned on. Then the point E has a fall from the VDD (4). In such a way, a simultaneous ON state is avoided for both TR29 and TR30, and a through current is prevented.

Title: Method for measuring characteristics of semiconductor laser wafer
Inventor: KATSUTA HIROHIKO
IPC: H01S5/042
Filed: 1985-04-26
Abstract: PURPOSE:To make it possible to evaluate a wafer without preparing an individual element, by cutting a semiconductor wafer, in which electrodes are formed on both surfaces, preparing rod shaped samples, contacting measuring electrodes between both electrodes of the sample, and measuring characteristics. CONSTITUTION:After electrode layers are formed on both surfaces, a semiconductor wafer is cut into rod shaped samples S. When the characteristics of a laser element included in the samples S are measured, the tip of a measuring electrode 12 and a protruded electrode 14a are contacted with the upper and lower surfaces of the samples S. A pulse current is supplied between an upper plate 11 and a base 14. Light emitted from the laser element is received, and the characteristics are measured. In this measuring method, since the protruded electrode 14a is provided, the current flows through a part of the sample concentratedly. Thus, the same effect, when a chip is prepared and measurement is performed, is obtained. In this method, the distribution of the light emitting characteristics can be readily checked by changing the position of the samples S.
