Title: Shaft sealing device for pump
Inventor: WATANABE SHIYOUSAKU
IPC: F04D29/10
Filed: 1981-04-10
Abstract: PURPOSE:To construct a packing in a structure which is inflated by pressure water and is capable of omitting adjustment for keeping its sealing performance and preventing leakage of water and at the same time which does not require so much time  for replacement of the packing. CONSTITUTION:A helical packing groove 2 of a shaft sealing box 1 is formed in such a  size that a packing 3 can be inserted into the groove 2 with ease in the state that the  packing 3 is not inflated with water, so that it can be inserted around a shaft 5 and  drawn out to the outside with ease from its closed top end portion 9. When a seal  water pipe 4 is connected to an opening end portion 10 of the packing 3 and pressure  water is charged into the same after insertion of the packing 3 into the groove 2, the  packing 3 is inflated and comes into tight contact with the outer surface of the shaft 5  since pressure of sealing water after subtraction of pressure loss caused by water  ejected to the outside from small holes 6 is acted in the hollow packing 3. On the  other hand, a small amount of water ejected to the outside from the small holes 6 of  the packing 3 serves to lubricate the sliding surface between the packing 3 and shaft 5,  so that frictional loss is not caused. Further, since the shaft sealing portion is sealed  by positively by a sealing means 8 of a cover 7, pressure water is not leaked to the  outside.

Abstract: PURPOSE:To materialize a fine multilayer interconnection by a simple process by detecting an oxygen element or nitrogen element in a marking layer formed on a specified region of a single-layer metal film in a dry-etching process of the metal film. CONSTITUTION:After forming a first interlayer insulating film 2 on a silicon substrate 1, a metal film 3 which consists of a first layer metal interconnect and a pillar is formed. Then, a resist pattern for interconnection 5 is formed on the metal film 3 and an upper-layer section 3a and a lower layer section 3b of the Al metal film 3 are processed under the same etching conditions to form a metal film pattern 6. Nextly, a resist pattern 7 for pillar is formed at a specified place of the metal film pattern 6 and the Al metal film 3 is dry-etched again. By this, an upper-layer pattern 6a of the metal film is etched and a marking layer 4 is exposed and thereby light is emitted which is peculiar to an oxygen element or nitrogen element contained in the layer 4. The emission is detected by an emission-spectrometer and etching is stopped. By this method, a metal film structure having a very precise unevenness can be manufactured easily.

Title: Yawing controller for vehicle
Inventor: SHIRAISHI SHIYUUJI
IPC: F02D45/00
Filed: 1987-03-09
Abstract: PURPOSE:To control the yawing of a vehicle, by correcting it with the reference yaw rate estimated on the basis of a detected yaw rate of the vehicle and hysteresis in the yaw rate. CONSTITUTION:Each signal out of speed sensors Sl and Sr for free rolling wheels Wrl and Wrr is inputted into a yaw rate detecting means 1 and thereby this time value and the last value or the like are found at each operation cycle of a yaw rate. A reference yaw rate generating means 2 calculates a reference yaw rate by hysteresis of a steering angle to be secured by a steering angle detecting sensor Ss and hysteresis of the yaw rate secured by the yaw rate detecting means 1. And, a difference between the detected yaw rate and the reference yaw rate is found by a subtracter means 3. Next, the difference is compared with the reference value by a comparator 5, and the result is outputted to an engine power controller 6, thereby controlling engine power. Therefore the detected yaw rate is controlled to the vicinity of the reference yaw rate, thus it is made so as to coincide with the yaw suitable to a driver's desire.

Title: Battery charger
Inventor: ABE SATORU
IPC: H02J7/04
Filed: 1990-03-05
Abstract: PURPOSE:To prevent a battery from being overcharged by connecting the output of a rectifier charging circuit connected in series with a drive coil and a contact which is opened and closed by means of the coil to a chargeable battery and supplying electricity to the coil by means of a definite-time continuity switch for a fixed period of time in the initial stage of charging. CONSTITUTION:When the alternating current of outside commercial power supply 8 is connected to a battery charger 1, a trigger generation circuit 3 for a definite-time continuity switch 4 generates a trigger pulse and the switch 4 is closed. Then a direct current generated by a rectifier charging circuit 2 starts to charge a chargeable battery 9 through the drive coil 7 of an electromagnetic relay 5 and, at the same time, the drive coil 7 closes a contact 6. The switch 4 is opened after the elapse of a prescribed period of time, but the contact circuit 6 is left closed due to self-holding. When the battery 9 is completely charged, no electric current flows through the coil 7 and the contact circuit 6 is opened, because the output voltage of the circuit 2 becomes equal to the voltage of the battery 9.
