IPC: H01L21/331
Filed: 1981-09-24
Abstract: PURPOSE:To prevent the expansion of the crack of a protective glass film and to simultaneously stop the invasion of mobile ion by removing the film on a field insulating film surrounded by a guard ring so as to surround a fuse part. CONSTITUTION:A region to form a guard ring is removed to form a field insulating film 2 on a semiconductor substrate 1. Polycrystalline Si films 3-1, 3-2  which contains impurity are covered on a region to form a guard ring, and are  heat treated, thereby forming diffused layers 4-1, 4-2 to become a guard ring.  When forming the films 3-1, 3-2, a fuse part 3-3 is also formed. Then, when the  surface is covered with a protective glass film 5, discontinuous grooves 7-1, 7-2  are formed on the film 5 to discontinuous grooves 7-1, 7-2 are formed on the  film 5 to surround the fuse part 3-3 on the film 2. In this manner, a crack which is produced at the film 5 can be stopped, it does not affect the infuluence to the other part.

IPC: B09B3/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To prevent a pathogenic microbe from proliferating and make a garbage disposer highly sophisticated in terms of hygenic consideration, garbage decomposition efficiency and the inhibition of generation of a small by operating the disposer in an operating mode for the inactivation of the pathogenic microbe for increasing the internal temperature of a decomposition tank compared to a routine operating mode, referring to an output from a detection means. SOLUTION: The operation of this garbage disposed is controlled by a control circuit 6 to select either of modes such as starting, routine operation, stopping and sterilization operation (operating mode for the inactivation of a pathogenic microbe) depending upon circumstances. To interpret the prevailing circumstances, outputs from a moisture content sensor 61 and a switch 62 are used with the making of a power supply and the setting of a built-in timer. The sterilization operation mode is a mode for executing the interruption of the routine operation mode for a specified time every specified time during the operation in the routine operation mode. When set in the sterilization operation mode, the internal temperature of a decomposition tank is maintained above the temperature level in the routine operation mode, e.g. 60 deg.C.  Further, a stirring means 3 is set to operate more frequently than in the routine operation mode. Besides, the ventilation level is also lower compared to the routine operation mode.

Title: Facsimile equipment
Inventor: NIRASAWA YOSHINOBU
IPC: H04M11/00
Filed: 1993-06-22
Abstract: PURPOSE:To improve the S/N and to obtain excellent reception data by measuring an incoming level of a signal with a signal arrived at first, attenuating the reception signal, including burst noise through the selection of a proper attenuation and suppressing only the noise component outside the dynamic range of a modem. CONSTITUTION:Upon the receipt of data, after a telephone line is connected, a CNG signal representing FAX transmission is received from an opposite transmitter at first. The CNG signal coming from a telephone line 6 is inputted to a level detector 3 via an attenuator 2 from a telephone line connection section 1. Upon the receipt of the CNG level, the attenuation of the attenuator 2 is set to 0dB. The detector 3 measures a reception signal incoming level by the CNG signal. An attenuator control means 5 adjusts the attenuation of the attenuator 2 so that an input level of a demodulator 4 reaches an upper limit when the input level of the demodulator 4 is more than the preset upper limit based on the result of measurement by the detector 3. In this case, burst noise (intermittent noise) is suppressed to the outside of a dynamic range of the demodulator 4 and the S/N is not deteriorated, then excellent reception data are obtained.

Title: Rotor for screw compressor
Inventor: NOZAWA SHIGEKAZU
IPC: F04C18/16
Filed: 1979-11-21
Abstract: PURPOSE:To prevent the leakage of gas and to prevent the deterioration of compression efficiency, by applying galvanization or coating of soft metal or synthetic resin on the advancing face of female rotor thereby achieving continuous face contact between the male and female rotors, due to the resilient deformation of soft material. CONSTITUTION:Number 3 is an advancing face or a driving face at the tip of tooth of a male rotor 1, while number 4 is an advancing face or a driving face at the tip of a tooth of a female rotor 2. Coating or galvanization of a soft metal or coating 5 of a synthetic resin is applied on said face 4. Consequently continuous face contact rather than intermittent line contact is achieved between the male and female rotors 1, 2 to prevent the leakage of compressed gas. Furthermore since soft material is employed fine foreign material is pressed and burried into the soft material, thereby the contact face of rotor isn't damaged while the soft material will function as a kind of buffer thus to reduce the noise of the compressor.

Title: Motive power controller for automatically driven vehicle
Inventor: KANEHARA HIROMITSU
IPC: B60K31/00
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of a vehicle running speed that is caused when the operation of an on-vehicle device is started and to reduce the variance of the vehicle running speed by detecting the timing estimating the start of operation of the on-vehicle device that serves as the load of a power source while a vehicle is running at a fixed speed and then increasing the output of the power source. SOLUTION: When an automatically driven vehicle enters a curved course and a mark 2 which is set at a spot where the start of operation of a power steering mechanism is estimated is detected (S4, YES), the opening degree A1 of an idle control valve is changed to a larger opening degree A2. Thereafter, the idle control valve undergoes the opening degree control (ISC2) by the degree A2 (S6, S7, S8). Thus, the vehicle can pass through the curved course while keeping almost a slow speed (creeping run) even when the load is varied to the engine at the start and end times of operation of the power steering mechanism under the control of the idle control valve.

Abstract: PURPOSE:To rapidly judge an inferior place by short-circuiting a signal wire and a ground wire on an attachment board. CONSTITUTION:In such a case that inferiority is generated in the continuity check between an LSI tester and a wafer in the attachment board 1a of a prober, when voltage is applied to a pad 3c, the contact of a relay circuit 2 is closed and a ground terminal (pad 3b) and a signal terminal (pads 3a, 3e, 3g) become a continuity state.

Then the inferiority between the LSI tester and the attachment board 1a is clearly discriminated from that between the attach ment board 1a and the wafer and the setting of an inferior place can be rapidly performed.
