Title: Multistage a/d converter
Inventor: ONO KOICHI
IPC: H03M1/16
Filed: 1992-02-03
Abstract: PURPOSE:To reduce deviation between A/D conversion blocks and to improve differentiation linearity by setting the positive phase input of an amplifier circuit, which amplifies difference between an input signal and a D/A output signal, at the reference level of an A/D converter(ADC) on the next stage. CONSTITUTION:A comparator 32 of a low-resolution parallel ADC 30 and a sample/hold amplifier 20 sample inputs at the same clock timing. The comparator 32 outputs digital data corresponding to the resolution of the ADC 30. A D/A converter 40 converts the digital data of the ADC 30 to an analog level again. The sample/hold amplifier 20 amplifies and outputs error signals. Plural A/D conversion blocks 60 are serially connected, digital data from the respective blocks 60 are added by an adder circuit 70, and high-resolution data are obtained. In this case, the minimum level of a reference voltage prepared by a resistor string (reference voltage generating circuit) 31 of the ADC 30 at the next stage block 60 is impressed to the positive phase input of an operational amplifier 21, and reference levels are made coincident.

Title: Diameter enlarging and retaining device for cylindrical member, and enlargement and reduction of diameter
Inventor: SAKURAI YUJI
IPC: H02G1/14
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To eliminate such operations as to form and melt a low-melting-point substance solidification layer, by using a cylindrical guide member having a diameter reduction part and a cylindrical hard inserting member having a diameter a little smaller than the inner diameter of the guide member. SOLUTION: A hard inserting member 20 and a guide member 10 are pulled out sequentially little by little. When the hard inserting member 20 and guide member 10 are pulled out sequentially little by little, the self-shrinkage force of a cylindrical member 30 pushes out the guide member 10, so that the guide member 10 can be pulled out easily. An antifriction is applied to the outer surface of the diameter reduction part 10C of the guide member 10, so that the guide member 10 can be pulled out more easily. When all of the hard inserting member 20 and guide member 10 are pulled out, the condition of diameter enlargement is released, and the cylindrical member 30 is closely fixed to the prescribed position of the terminal of a power cable by self- shrinkage force.

Title: Solenoid valve
Inventor: OOTA TERUAKI
IPC: F16K31/06
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To easily provide a compact solenoid valve. SOLUTION: A solenoid valve 10 involves a moving core 24 arranged outside a coil 32 so as to reciprocate in the direction perpendicular to the axis of the coil 32. That coil 32 not enclosing the moving core 24 is thus reduced in its size. The location of the coil 32 outside the reciprocating path of the moving part constituted of the moving core 24 and a valve element 25 also contributes to the smaller size of the moving core 24. The electromagnetic force required to attract the moving core 24 is thus correspondingly lessened to help to further reduce the size of the coil 32 and resultantly the total size of the solenoid valve 10. The annular portion 22a of a stationary core 20 encloses the moving core 24 for its uniform magnetic flux density to thereby attract the moving core 24 evenly.

Abstract: PURPOSE:To provide the titled fine particles composed of diastase, a vehicle and a binder, having excellent property and free from the drug dust allergy caused by scattering. CONSTITUTION:A mixture of diastase, a vehicle (e.g. dextrin, lactose, etc.) and a binder (any kinds of water-soluble binder, alcohol-soluble binder and binder soluble in a mixture of water and alchol can be used; e.g. hydroxypropyl cellulose, dextrin, polyvinyl pyrrolidone, etc.) is granulated in the presence of a solvent such as isopropanol by a wet-granulation process to obtain fine particles of diastase. The binder is effective to promote the bonding of the granules and prevent the scattering of the powder. the effect becomes poor when the amount of the binder is too small, however, excessive binder causes the production of coarse particles having poor distintegrability. Accordingly, the amount of the binder is selected to 0.5-3.0wt%, preferably 1.0-2.5wt%.
