Patent JP-H08331789-A (JP)
Title: Housing and small-sized dc motor using the housing
Inventor: SUDA HIDETOSHI
IPC: H02K5/00
Filed: 1995-06-01
Abstract: PURPOSE: To reduce electric noise and to improve the release strength of a bracket. CONSTITUTION: The housing comprises a metal case, and a bracket engaged with the opening of the case, wherein a groove 2b is formed from the outside on the entire outer periphery 2a of the bracket 2. The outer periphery of the bracket is formed slightly larger than the diameter of the opening of the case. Thus, when the bracket is press-injected in the case, the outer periphery 2a of the bracket has elastic properties in the radial direction, and hence the bracket can be press-injected without deflecting the case, and the adhesive properties can be improved. Even if the force from the inside is developed at the bracket, the force is developed in the direction of intruding the outer periphery into the opening of the case by the groove, and the bracket is scarcely drawn.

It the lead X and the substrate (b) are conductors, the lead X serves as the electrode terminal of a second electrode. The substrate enlarged in order to form the second electrode has space width of 700 μm, for example. It means significant saving of space as compared with a conventional second electrode having space width of several mm.

IPC: G01N19/02
Filed: 1988-06-30
Abstract: PURPOSE: To precisely and quickly estimate the abrasion and frictional characteristic of a material by moving an eccentric ring and disk relatively to each other by a certain distance under a set load in a state where a lubricant is interposed between the contact surfaces of the ring and disk and plotting the energy consumption on a graph as the function of the temperature of the lubricant. CONSTITUTION: A shaft 3 and, accordingly, an eccentric ring 5 are rotated against a disk 2 by means of a motor 6. A coil spring 2 presses the disk 2 to follow the eccentric rotation of the ring 5. A lubricant in a housing 17 is maintained at a prescribed temperature by means of a control unit 22. A torque recorder 12 measures the reaction moment generated by the friction between the disk 2 and the ring 5 attached on the shaft 3. The energy consumed by the friction between the disk 2 and ring 5, is calculated from the moment. The control unit 22 records the consumed energy together with the temperature of the lubricant and repeats the recording of the energy consumption and lubricant temperature many times whenever the temperature rises. Then the energy consumption is plotted on a graph as the function of the temperature of the lubricant.

Title: Transmission system for extension telephone
Inventor: SAGAWA SHUICHI
IPC: H04Q3/58
Filed: 1986-07-08
Abstract: PURPOSE:To elevate the efficiency of a work such as a business management by counting a prescribed dialing from a caller extension telephone set during a call from the caller extension telephone set to a callee extension telephone set, and storing the state of the result of a dialing in a memory, in the system for an extension telephone at a PBX. CONSTITUTION:When an extension telephone TELA1 transmits and calls a TELB2, on the off-hook of the TELA1, a CPU11 decides to be the call of the TELA1 and connects a transmitting register trunk ORT7 and a transmitting trunk DT8 to a channel switch SW5. When a dial tone from the DT8 is recognized at the TELA1, the extension number of the TELB2 is dialed. Here, if a previously decided special number is dialed from the TELA1, the CPU11 receives the number information of this special number, and sets a flag which shows that the TELA1 is calling the TELB2, to the memory MEM12. Thereupon, the operator of the TELA1 is temporarily released from the TELA1. Consequently, the operator can use effectively a time he is released from.

Title: Manufacture of semiconductor device
Inventor: TAKABAYASHI SEIICHIRO
IPC: H01L21/768
Filed: 1986-07-08
Abstract: PURPOSE:To obtain a semiconductor device to which fine processing can be applied by a method wherein apertures in an insulating film are completely formed by dry etching and then contaminant metal on the contaminated surface is removed. CONSTITUTION:Apertures 6A and 6B for taking out electrodes are formed in an insulating film 4 on source/drain diffused layers 2 of a semiconductor device MOSFET formed on a silicon substrate 1 by reactive ion etching. Then a polycrystalline silicon film 8 is formed over the whole surface including the apertures 6A and 6B by vapor growth. In this process, contaminant metal produced by reactive ion etching is taken into the polycrystalline silicon film 8. Then the contaminant metal is removed by removing the polycrystalline silicon film 8 formed on the surface by wet etching or dry etching. As the dry etching in this case is the etching of the whole surface of polycrystalline silicon, anisotropic etching is not required and the etching can be carried out by an isotropic etching system of a low vacuum rate so that power consumption is low and metal contamination will not occur.

Title: Remote control system
Inventor: HONMA HIROSHI
IPC: H04Q9/14
Filed: 1982-09-16
Abstract: PURPOSE:To simplify the transmission circuit of a calling pulse signal from a host machine by operating a selected control content when the high level state of the calling pulse is released at a control terminal device. CONSTITUTION:When the calling pulse from the host machine is received at a calling signal detecting circuit 4 of the control terminal device, this pulse is given to a counter 9 via a pulse delay circuit 5 and the counter 9 starts counting the pulse. When the counter 9 counts a pulse signal coincident with an address set to an address set circuit 10, the control content is selected and a circuit section operating a load is brought into an operative state. A monostable multivibrator 27 of the circuit section detects that the calling pulse from the host machine falls down from a high to a low level L. A load selecting signal is outputted from any gate circuit 18 of photocouplers 24A-24C with the detecting signal and a selected load is controlled. Since the calling pulse can be a pulse train corresponding to one pulse per each terminal device in this constitution, the circuit is simplified.

IPC: G11B20/02
Filed: 1993-06-30
Abstract: PURPOSE:To prevent a muting function operated undesirably at the changeover of sound quality and sound field. CONSTITUTION:When a sound selector 1C and a position selector 1B are used to select the sound quality mode and the sound filed mode by operating a sound switch 8A and a position switch 8B, characteristic differences before and after the changeover are compared by a characteristic comparison means 9A and a muting control means 9B inhibits the operation of a muting circuit 4 when the characteristic difference is below a predetermined level and muting is applied when the characteristic difference is larger than the prescribed level. Thus, production of noise sound is eliminated at the changeover between different sound quality characteristics or different sound fields and undesired sound interruption at the changeover between same sound quality characteristics or between same sound fields.

Abstract: PURPOSE:To obtain a solid fuel which exhibits a high calorific value and burns for a long period of time and has an excellent ignitability, by kneading an alcohol contg. a binder with charcoals and lime or ash or soil to solidify them. CONSTITUTION:An alcohol fuel is kneaded with charcoals such as charcoal and anthracite and lime, ash or soil to allow them to solidify. At least the outer surface of the solid fuel may be covered with a material obtd. by gelation of an alcohol with a metal salt of a higher fatty acid, sorbitol or nitrocellulose. Further, the solid fuel may be packed in a resin container, etc., having self- ignitability, followed by sealing of the container. Examples of the alcohol with which the charcoals are impregnated include methanol, ethanol, propanol and butanol. Since the use of only methanol leads to the formation of formalin during combustion, it is preferable that the amt. of alcohols to be added be adjusted.
