Title: Dry etching
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1988-09-21
Abstract: PURPOSE:To realize a dry etching method, for silicon system material, which can excellently obtain a trench having a desired shape, especially, a trench having a tapered shape and the like by using etching gas containing at least boron chloride and nitride in an etching process. CONSTITUTION:In a dry etching method wherein silicon system material 3 is subjected to selective etching, etching is performed by using etching gas containing at least boron chloride and nitrogen. For example, a mask 2 composed of SiO2 is formed on a single crystal Si substrate 3, and etching is performed by using etching gas of BCl3/N2=40/10 SCCM and under the conditions where pressure is 10mTorr and applied voltage Vdc=-250 volts. SiO2 as the mask 2 is favorably retreated and turned into a tapered shape. As a result, a trench 1 having an excellently tapered shape can be obtained. Thereby, the etching for a desired shape such as a tapered shape can be attained without accompanying problems like the occurrence of bowing and the occurrence of dry etching also can be prevented.

Abstract: PURPOSE:To reduce the size and weight of an apparatus by mounting a pressure plate on a hub in such a manner as to rotate freely in one body, and interposing a return spring between the pressure plate and the hub. CONSTITUTION:When pressure oil is introduced from a hydraulic power source through a hub 11b into an oil pressure chamber 13, a piston 12 is slid to press a pressure plate 18 through a bearing 19. The pressure plate 18 is slid to a hub 15 against a return spring 20 to press friction plates 16, 17 to be engaged with each other, whereby a drum 14 and the hub 15 are rotated in one body to transmit power. When oil pressure in the oil pressure chamber 13 is discharged from the hole 11b, pressing force produced by the piston 12 is out, and the pressure plate 18 is pushed back by the return spring to release the engagement of the friction plates 16, 17. As the piston 12 is disposed on the fixed housing 11, it is possible to reduce the axial length of the drum 14 and make the drum small-sized.

Title: Device for detecting information on contact
Inventor: KISHIMOTO MICHIHIRO
IPC: G01R31/00
Filed: 1989-09-12
Abstract: PURPOSE:To surely detect the state of a contact to be measured, by connecting the title device directly to the contact and by absorbing a surge received from this contact by a surge absorbing circuit. CONSTITUTION:A contact information detecting unit 10 is constructed of a surge absorbing circuit 11 connected to a contact to be detected, a bridge circuit 12 of an impedance measuring circuit and a power circuit 13. When a contact 29 is closed, a current flows through a diode 23, a resistor 17, the contact 29 and a transistor 24, the bridge circuit 12 is balanced thereby and the current does not flow to a photocoupler 28. When the contact 29 is opened, however, the balance of the bridge circuit 12 is lost, the current flows to the photocoupler 28 and a signal representing a conducting state is generated on the secondary side thereof. In the case when a circuit to be measured is an alternating-current circuit, the current is bypassed through the transistor 24 and a diode bridge 30 when a negative half-wave is impressed on terminals 34 and 35, and therefore it does not produce any effect on the bridge circuit 12. Accordingly, the state of the contact is surely detected.
