Title: Semiconductor device
Inventor: SAITO MUTSUO
IPC: H01L23/50
Filed: 1987-12-17
Abstract: PURPOSE:To obtain a semiconductor device in which an electric short-circuit between wirings can be effectively prevented by providing a protrusion at the inner end of the step of a package base or providing a protrusion at a bonding lead attached to the step in a structure for preventing the wiring from hanging. CONSTITUTION:A semiconductor chip 6 is placed in a recess of a package base 1, bonding leads 4 formed at the step 7 around the recess are bonded by wirings 5 to the input/output pads of the chip 6, and the top of the base 1 is sealed by a cap 2. In such a semiconductor device, a protrusion 10 is formed at the inner peripheral end of the step 7, or protrusions 8 are formed at the inners end of the leads 4, thereby preventing them from contact with each other due to the hanging of the wirings 5. Thus, it can prevent the loop of the wirings 5 from hanging and prevent adjacent wirings from contact. Accordingly, an electric short-circuit between wirings can be prevented.

Title: Data communication system
Inventor: SHINOZAKI GORO
IPC: H04B7/08
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To reduce a data transmission error in the vehicular communication under interference fading with a property where a fading period depends on a transmission carrier frequency. SOLUTION: Preset data added to a conventional signal are set from a transmitter 2. The data are inserted for each period selected in a range of, e.g. 1/3-1/4 of one period depending on a transmission carrier frequency. A receiver 6 uses additional data detection section 6c to detect the additional data. When the detection section 6c detects the additional data, a diversity reception control section 6a conducts diversity reception. Thus, the effect of a switching noise or the like produced at antenna changeover in the case of diversity reception control onto information data is reduced.

IPC: G01N29/44
Filed: 1991-12-04
Abstract: PURPOSE:To realize the ultrasonic diagnostic device which can execute a scan so as to obtain a tomographic image of a body to be examined by transmitting and receiving a continuous wave by a CW Doppler system and executing transmission/reception by a B mode system, while measuring a moving speed of a reflecting body. CONSTITUTION:In a B mode system, a transmitting signal oscillator A2 generates s transmitting signal of a burst number (n) and a frequency fB and transmits it from a B mode probe 5 by a pulse input from a pulse oscillator 1. A receiving signal is filtered by a band pass filter A6 of a center frequency fB and band width (2/n) fB and outputted. In a CW Doppler system, a transmitting signal oscillator B 11 oscillates a signal of a frequency fD of fD ={1+(1/n)} fB and transmits it from a transmitting probe 13. A reflected wave is received by a receiving probe 14, filtered by a narrow band pass filter B16 of the center frequency fD and outputted.

Title: Method and device for detecting bar code
Inventor: KIKO KATSUNOSUKE
IPC: G06K7/10
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To highly accurately and quickly detect a bar code by executing Fourier analysis to the inside of a detected area candidate, finding out the periodical characteristics of pixels corresponding to the bar code from an image in the area candidate and detecting the bar code. SOLUTION: A prescribed image pickup area in a bar code detection object P is optically picked up by a CCD camera 1 e.g. with a previously determined resolution and converted into a digital signal by a photoelectric conversion part 2. A bar code detection part 3 based upon neighborhood connection applies differential, expansion, degeneration, and labeling processing to inputted picture data to detect an area candidate of a bar code. A control part 5 informs a bar code detection part 4 based upon Fourier analysis of the position information of the area candidate detected by the detection part 3. The detection part 4 locally applies Fourier analysis to the restricted area or its area candidate and informs the control part 5 of the Fourier analytical result.

Title: Semiconductor laser
Inventor: UENO YOSHIYASU
IPC: H01S5/00
Filed: 1993-12-20
Abstract: PURPOSE:To extract oscillation light in a fundamental transverse mode from a verditer blue group II-VI semiconductor laser. CONSTITUTION:A striped ridge is formed on a P-type ZnMgSSe clad layer 5 and thereafter, an N-type SixGe1-x layer 6 is formed outside of the ridge. As the constituent atoms of the layer 6 are a group IV element, the conductivity type of the layer 5 is not changed even if an interdiffusion is performed in the layer 5 adjacent to the layer 6. Accordingly, the generation of a reactive current due to inversion of the conductivity type of the clad layer can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display having a high contrast ratio and high image quality by selectively spraying spacers for maintaining the spacings of a substrate assembly only to the non-pixel parts so as not to hinder the light passing effective pixel parts. SOLUTION: Voltage of (+) polarity is impressed through a power source on a transparent conductive film 22b to electrify this film in the state of arranging the substrate assembly 22 in a hermetic vessel in such a manner that an alignment layer 22c is positioned on the upper side. The spacers 26 which have the electric charges of (+) polarity and are housed thus far in a housing container are pressurized in this sate by the gaseous nitrogen supplied from a storage tank. When the spacers 26 are injected through an injection means and are sprayed atop the layer 22c, the spacers 26 are sprayed only atop the layer 22c corresponding to the non-pixel parts B. Repulsion is generated between the spacers 26 and the transparent conductive film 22b in such a manner, by which the spacers 26 are sprayed only atop the layer 22c corresponding to the non-pixel parts B.

Title: Hydraulic generating acceptor for transmitting power by improving hydraulic balance
Inventor: JIYAN MARUFUI
IPC: F03C2/24
Filed: 1993-11-26
Abstract: PURPOSE: To obtain static pressure balances in axial direction and tangential direction by varying sector surface of an envelope adjacent to engagement point until it becomes an obstacle of a permanent high pressure zone while obtaining axial balancing of a driving gear by varying value of surface of the permanent high pressure zone. CONSTITUTION: Main body of the apparatus is composed of a driving gear 9 and a driven gear 10. When inter balancing is ensured by a hydraulic coil system and an engagement without clearance, inter sealing is realized by two side plates 21, 22, and a soft system comprising an envelope 36 provided with static pressure compensation generated by sectors 60', 60". In this invention, balancing in axial direction of the driving gear 9 is effected by varying value of the surface of a permanent high pressure zone 34. The value variation causes an application of the high-pressure on one of the side plates and does not cause influence on the other side plate. In addition, in order to obtain tangential balancing of the driving gear 9, sector surface of the envelope 36 adjacent to the engagement point 3 is varied until it becomes an obstacle of the zone 34.

Title: Safety device for pressure governor valve
Inventor: KAJIKAWA SHINICHI
IPC: G05D16/20
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To easily and securely prevent danger such as explosion due to an increase or decrease in internal pressure by closing a solenoid valve unless detected pressure is within a specific pressure range, and cutting off the supply of working oil for rod retraction to a hydraulic cylinder and closing the valve. SOLUTION: A CPU 4 reads in the value of a manometer 2A and stores the value in a register. When the value in the register is within the specific pressure range, the solenoid valve 3 is opened, or turned on, so the pressure governor valve 1 is open. If, however, the value in the register is not within the specific pressure range, the solenoid valve 3 is closed, or turned off. Consequently, the supply of the working oil for rod retraction to the hydraulic cylinder is cut off, so the rod moves forward with the reaction force of a spring member to close the pressure governor valve 1. Thus, the pressure governor valve l is closed mechanically and automatically through the operation of the spring member in case of emergency such as large pressure variation in a tube, so safety is obtained.
