Title: Stencil printing machine
Inventor: FUKAZAWA TOSHIO
IPC: B41L13/10
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To contrive the miniaturization of an apparatus without deteriorating its functions, the reduction of noise, and the curtailment of costs by a method in which a stencil base sheet is fixed to a plate cylinder, desired printing is done, and a clamp means for holding the base sheet on the plate cylinder is made to comprise an electrostatic attraction system. SOLUTION: When a plate cylinder 1 is rotated, or in a process from plate making to printing through plate setting, a base sheet is attracted and held by an electrostatic attraction sheet 181. When the plate cylinder 1 is not rotated, the current passing through the sheet 181 is turned off, and the base sheet is held by a master clamp 197. In this operation, a solenoid is magnetized, a master clamp holder 193 and the master clamp 197 are separated from the plate cylinder 1 not to rotate integrally. Since the sheet 181 is used as a clamp means 49a not projecting from the plate cylinder 1, there is no need for securing a wide space on the periphery of the plate cylinder 1 when it is rotated so that the miniaturization of an apparatus and the reduction of costs can be attempted.

Title: Detecting method for quantity of refrigerant for boiling cooling device
Inventor: WATANABE TAKASHI
IPC: H01L23/44
Filed: 1982-10-14
Abstract: PURPOSE:To detect the displacement of the level of the refrigerant by setting up a first temperature measuring resistance element at a predetermined position in a refrigerant liquid, fitting a second temperature measuring resistance element at a predetermined position of the upper section of the surface of the refrigerant in a vessel and giving an alarm to the outside while interrupting an electric circuit. CONSTITUTION:A liquid-phase refrigerant 3 is bubbled and rises through a heat exchange with heat generated from a semiconductor element 1, and is changed into a gaseous-phase refrigerant 10. When the electric circuit is operated, the gaseous-phase refrigerant 10 balances with the radiant effect of fins 6 because heat is generated from the semiconductor element 1, and reaches even several atmospheric pressure at a maximum. The first temperature measuring resistance element 7 is positioned in the liquid when a liquid level is kept at the position of a solid line, but the first temperature measuring resistance element 7 is exposed to the outside of the liquid when the liquid level is positioned at a dotted line 20, thus easily grasping the lowering of the liquid level. When the liquid is supplied, on the other hand, the liquid level exceeds the second temperature measuring resistance element 9 when a screw 12 fitted to a cover 5 is unfastened and the refrigerant is injected from a hole 13, and the second temperature measuring resistance element 9 dips in the liquid when the liquid level reaches a dotted line 21, thus easily confirming the rise of the liquid level.

IPC: H01L29/861
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To adjust resistance independently of the concentration of Si donor impurities in an electron supply layer by providing the Si donor impurities whose effective donor concentration in a part or a plurality of parts is adjusted with F impurities. SOLUTION: A resistor is composed of an i'-InP substrate 10, an i'-In0.5Al0.5As buffer layer 11, an i'-In0.5Ga0.5As channel layer 12 and an n'-In0.5Al0.5As electron supply layer 13 sequentially from the lower part. The resistor is provided with Au/Ni/Ge electrodes 15, 16, and it obtains the contact of electrons with the i'-In0.5Al0.5As channel layer 12 by using the electrodes. Due to the difference between silicon donor impurities between the supply layer 13 and the channel layer 12 and an electron affinity, the electrons inside the channel layer 12 are stored, and a conductive route is formed between the electrodes. A new part in this structure is the supply layer between the electrodes 15, 16 whose F impurities are at a concentration of 5×1017 cm3. The F impurities offset the electron attraction action of the Si donor impurities.

Title: Armature for electromagnetic clutch and its manufacturing method
Inventor: ONO MITSUYA
IPC: B22F7/06
Filed: 1987-07-20
Abstract: PURPOSE:To improve engagement intensity by means of a double flux system by constituting an armature to consist of one non-magnetic or a feeble magnetic section at least and of ferro-magnetic sections adapted to hold the former at both sides. CONSTITUTION:An armature 12 in a disc form consists of three sections, namely an outer side, an intermediate and an inner side section.

Title: Mass flowmeter
Inventor: HASEGAWA HIROAKI
IPC: G01F1/84
Filed: 1987-07-20
Abstract: PURPOSE:To simplify a construction, to improve the accuracy of detection and also to improve the precision of a sensor tube, by using a sensor tube extending straight. CONSTITUTION:An apparatus is constituted by a sensor tube 3 constructed by extending straight a pipeline 2 through which a fluid to be measured passes, a driving element 1 making the tube 3 bent in the direction perpendicular to the direction of the above extension and making it conduct a circular motion, and a pickup 12 (12a, 12b) detecting the displacement of the tube 3 when the tube 3 is driven by the driving element 11 and makes the circular motion. When a driving pipeline 3c of the tube 3 is made to conduct the circular motion by a coil member 14 (14a, 14b) of the driving element 11, a Coriolis force corresponding to a mass flowmeter of the fluid to be measured is generated in the pipeline 3c and a detecting pipeline 3d. In the pipeline 3c, accordingly, a displacement of -delta (or +delta) indicated by a broken line is generated between a point (a) (or supporting members 10a, 10b) of an inflow port 4 and a point (o) at an intermediate position facing the coil member 14. Since this Coriolis force is expressed by a prescribed formula, the rate (mV) of mass flow running through the tube 3 is obtained by determining an angular velocity omega and the Coriolis force.

Title: Positioning device to recording track and method therefor
Inventor: KAARU AANORUDO BERUSAA
IPC: G11B21/08
Filed: 1990-07-10
Abstract: PURPOSE: To attain a quick and highly reliable positioning movement by providing a positioning servo system with a digitized speed signal generation means. CONSTITUTION: Digitalization of speed measurement uses a relatively constant measurement period, and in this case, the sampling ratio of track intersection is inversely proportional to a speed curve. Therefore, while a dynamic operation range for an analog circuit is maintained on a low side to generate a measured speed signal with a higher fidelity, a digital value module can be made the same. A reference speed signal is given by a ROM 175 via a bus 203. When receiving the digital value, DAC 204 converts it into an analog form, and a circuit 205 filters it in low-band and gives an analog reference speed signal via a line 132. Thus, a quicker and a highly reliable track trapping or servo positioning is possible.
