Title: Electrostatic joining jig
Inventor: OMURA YOSHITERU
IPC: B23K20/06
Filed: 1988-08-02
Abstract: PURPOSE:To provide an electrostatic joining jig capable of preventing defective joints reliably and capable of completing electrostatic joining in a short period of time by starting application of a voltage to a voltage applied surface of an insulator wafer from a central region having a predetermined small diameter and enlarging the voltage applied region from the central region towards the periphral region with the lapse of time. CONSTITUTION:An electrostatic connecting jig according to the invention comprises a central electrode 31, peripheral electrodes 32, 33 and an electrode driving mechanism. The contact area in which the jig is in contact with a voltage applied surface 20a of a insulator wafer 20 to be electrostatically joined to a semiconductor wafer 10 is enlarged from the central region towards the peripheral region with the lapse of time from the start of application of a voltage. For example, the area where a voltage is applied to the material set on the jig is enlarged from the central region towards the peripheral region of the voltage applied surface with the lapse of time by switching electrodes to be driven among a plurality of electrodes arranged concentrically. Accordingly, it is possible to minimize defective joints which would be observed as bubbles in the joint interface 10b between the semiconductor wafer 10 and the insulator wafer 20 or local projections or cracks in the semiconductor wafer 10. As a result, a semiconductor product having high reliability can be obtained.

Title: Production of ultrapure water
Inventor: HIRATA NAMI
IPC: C02F1/58
Filed: 1990-07-23
Abstract: PURPOSE:To obtain ultrapure water of low dissolved oxygen which is not obtainable heretofore by combining a deoxidizing blank material and the flocs of an ion exchanger having the excellent capacity to produce the ultrapure water. CONSTITUTION:The ultrapure water of about <=10ppb concn. of the dissolved oxygen is obtd. by treating raw water with the deoxidizing blank material and the ion exchanger. The deoxidizing blank material for which an oxidation reduction reaction is utilized can remove the dissolved oxygen of the ultrapure water to the extreme limit and is, therefore, preferable. The ion exchanger to which a metal is applied has the high deoxidizing efficiency in the production line of the ultrapure water, is economical, is usable in a large amt. and is, therefore, most desirable. The form of the ion exchanger to constitute the base body is arbitrary. While an ion exchange resin is generally economical, an ion exchange fiber is more preferable in terms of the large specific surface area of activation and high reactivity. The deoxidizing blank material and the ion exchanger are usable in an arbitrary form. Such forms include a resin, cut fiber, filament, braided cord, knitted cord, paper, felt, nonwoven fabric, etc.

Abstract: PURPOSE:To decrease the voltage of an electrolytic cell without degrading electric current efficiency in an electrolytic cell for aq. alkali chloride solns. using a cation exchange membrane by bringing an anode into tight contact with one side of the exchange membrane and a cathode with the opposite side via a conductive member. CONSTITUTION:A diaphragm used for a diaphragm type electrolytic cell for aq. alkali chloride soln. of NaCl or the like is constituted of a porous cation exchange membrane 1 of metallic oxide or the like having no electrode activity on at least one side thereof, and an anode 2 of a perforated Ti plate, meshes, or the like is brought into tight contact with one surface thereof.

Abstract: PURPOSE:To prevent a cup-type vending machine from being sellout state and to increase the sales chance with by detecting the state of a exhaust water bucket a little before this bucket is filled with water and then evaporating the water in the bucket by a heater. CONSTITUTION:A heater 3 is provided to evaporate the water in a exhaust water bucket together with a 2nd water volume detector means (water level 80% detector SW 2B) which detects the 2nd water volume smaller than that detected by a lst water volume detector means, and a control means 1 which turns on the heater 3 based on at least the result of the 1st water volume data detector means and then turns off the heater 3 based on the result of the detector SW 2B. The means 1 also turns on the heater for each detection of the water volume with the detection signal of a full bucket with exhaust water near end detector SW 2A which detects a substantial full-bucket state (95% water level) of the exhaust bucket of a cup-type vending machine. Thus the water is evaporated in the exhaust water bucket. In such a constitution a sellout state due to the full bucket with exhaust water can be prevented and the sales chance can be increased.

Abstract: PROBLEM TO BE SOLVED: To enhance controllability of a prime mover by connecting an internal combustion engine with an electric motor via a clutch, determining an angle of an output shaft of one prime mover by referring to detection value of an angle of an output shaft of the other prime mover, and calculating angle difference between an output shaft of the internal combustion engine and that of the electric motor for every clutch engagement. SOLUTION: In a driving unit 10 where an engine 12 is connected with a motor generator 14 via a clutch 16, it is judged during engine 12 operation whether condition is appropriate for learning a crank angle or not. When judged YES, output from an encoder 34 is monitored, and output value from a resolver 38 at the time when a top dead center in an explosion stroke of a first cylinder is detected is stored as a 0 degree crank angle. This angle is angle difference between a crank angle and a rotor angle. Then, when a command for starting the engine is given and there is no history of disengagement of the clutch 16 found, a crank angle is calculated based on output from the resolver and a relative angle. Then, commands for ignition or the like are delivered to a cylinder that comes to a top dead center in a next explosion stroke.

Title: Antilock control for vehicle
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/58
Filed: 1987-08-07
Abstract: PURPOSE:To prevent the increase of the brake distance by suspending and holding the pressurization of the brake hydraulic pressure for the rear wheels when the rear wheels are locked previously to the front wheels and carrying out the antilock control, having the front wheel speed as standard. CONSTITUTION:If the rear wheel speed lowers than the normal speed during the pressurization or holding of the brake hydraulic pressure, a signal is outputted into a comparison circuit 28, and sent into a flip-flop circuit 29, and a cut value CVa is closed. Therefore, the brake hydraulic pressure on the rear wheel side is maintained. If the brake hydraulic pressure for the front wheel is in pressurization and holding after the lapse of a prescribed time T1, and the rear wheel speed is restored to the normal state, the cut valve CVa is opened and closed little by little. Therefore, the brake hydraulic pressure on the rear wheel side is gently increased in stepwise ways. Therefore, the brake distance can be reduced, preventing the lock for the wheels.
