Title: Mobile communications system
Inventor: ASAMI HIROAKI
IPC: H04W4/08
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To enable simultaneous up and down data transfer and to enable efficient data communication by simultaneously and respectively operating up and down data transfer means. SOLUTION: The transfer procedure of up data from mobile stations 41-43 to a base station 21 uses a base station guided polling control system on a communication channel, and when connecting a call on a control channel with the mobile stations 41-43, the base station 21 applies transmitting instructions successively to one of plural mobile stations existing on the allocated channel. When there are data to be transmitted, the mobile station designation by a transmission instructor number in the header part of a down radio signal sets a data link with the base station 21, while using a control field and transfers the data using a resending procedure after that setting. At the time when the data have been completely transferred, the link is opened.  When the data from the mobile station having a transmission request are completely received, the base station 21 applies the transmitting instruction to the next mobile station.

Title: Manufacture of semiconductor device
Inventor: GOCHO TETSUO
IPC: H01L21/768
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To form a compensation diffusion layer at a low temperature at which a metal silicide does not agglomerate, to prevent the silicide from agglomerating when an impurity diffusion layer is formed and to restrain a rise in a resistance value by a method, wherein ions are implanted under a background pressure at a specific value or lower. SOLUTION: Phosphorus ions as n-type impurities are implanted into a contact hole in a p-well region, by using an ion implantation apparatus in which a background pressure is at 1.3×10<-7> Pa or lower. Similarly, boron ions as p-type impurities are implanted into a contact hole in an n-well region by using an ion implantation apparatus, in which a background pressure is at 1.3×10<-7> Pa or lower. The ions are heat-treated at 600 deg.C or lower in a nitrogen atmosphere, and compensation diffusion layers 8', 9' are formed. In this manner, since the background pressure is set at 1.3×10<-7> Pa or lower when the ions are implanted, the impurities can be sufficiently activated, even without executing annealing operation at a high temperature.

Abstract: PURPOSE: To solve the sunshine problem in densely housed estate by an easy-to- handle method by finishing the inside surface of an opened box to a reflector, further suspending a multiplicity of small pieces of reflector on the inside surface and letting the collected rays reflect irregularly to the shade portions.  
     CONSTITUTION: A reflector 2 of aluminum foil or the like is held affixed on the inside surface of a box body 1. A transparent cover 5 is mounted with an inclination at the angle at which the sunlight is easy to enter. A multiplicity of reflecting pieces 3 made of aluminum foils or the like are suspended by cords to the inner side of the box. More specifically, the light entered from the cover 5 surface irregularly reflects on the reflecting pieces 3 and the reflector 2 on the inside surface of the body 1, goes crooked and gives sunshine to the shade portions from the bottom plate 6. The irregular configuration of the reflecting pieces 3 obviates the movement of the body along with the incident angles from the sun as in the case of mirrors and the problem of sunshine in densely housed estate may be solved through the use of aluminum foils which do not require flatness like mirrors.

Filed: 1988-06-27
Abstract: PURPOSE:To reduce the size of an opening for obtaining a semiconductor device with improved integration by forming a second insulation film at the side wall part of the opening for contact with an emitter area. CONSTITUTION:After a semiconductor device forms an N-type embedded layer 2 on a P-type silicon substrate 1, an N-type epitaxial later 3 is accumulated over the entire surface the substrate, an oxidation silicon film 4 is formed on it, and a base area 5 is formed selectively by the ion implantation method. Then, an opening part is formed by opening the oxidation silicon film 4 on the base area 5 so that the base area may be exposed selectively and a second insulation film 7 consisting of nitride silicon is formed over the entire surface of a substrate including the opening part, the entire surface is etched back by anisotropic etching. Then, since the second insulation film 7 remains on the side wall part of the opening, the diameter of the opening part becomes small. Then, a polycrystal silicon film 9 is formed over the entire surface of the semiconductor substrate, an emitter area 6 is formed by implanting ions, and an aluminum electrode 8 is mounted and selectively etched for formation. Thus, current density passing through the opening part can be increased for achieving an increased integration.

Abstract: PURPOSE:To obtain a high-sensitivity, superior-linearity pressure sensor whose decrease in reliability is suppressed while the evil influence of a protective resin film is reduced, by covering a semiconductor pellet for the sensor with the prescribed thin protective resin film. CONSTITUTION:A pellet 2 made of a semiconductor of hollow structure mounted on a package substrate 1 and positioned inside of a sealer cap 5 is protected from the outside air by a thin protective film 14 of silicone resin which has <=100mum thickness. The influence upon the strain rate of a diaphragm is nearly disregarded because of the thickness of the protective resin film. Further, the sufficient operation of the protective film on the outside is maintained. Therefore, the decreases in sensitivity and linearity of the protective resin film 14 are evaded and the reliability of a pressure sensor is improved sufficiently.

Thus the desired picture information signal is selected. The character pattern signal (serial data) which is controlled so as to have synchronization with the selected picture information signal is supplied to the part 13 from a character pattern generating part 8. Then a specific logical operation is applied to both picture information and character pattern signals for each picture element.

Title: Wear detector
Inventor: KAWAGUCHI AKIMITSU
IPC: G01B7/00
Filed: 1994-07-12
Abstract: PURPOSE:To detect wear of a screwed surface automatically by screwing a valve shaft down on a drive sleeve to allow reciprocal driving in the direction of an axis line while a dummy ring is screwed down having a freedom in the direction of the axis line of the drive sleeve to provide a detection circuit on the dummy ring. CONSTITUTION:A thread part 2a is screwed down on the circumferential surface of a valve shaft 2 to match a thread part 1a of a drive sleeve 1. The material of the drive sleeve 1 is lower in hardness than the material of the valve shaft 2, so that the thread part 1a of the drive sleeve 1 wears earlier than the thread part 2a of the valve shaft 2. When a matching of a coil is made by adjusting a distance between a dummy ring 14 and a mounting base 9 on the output side, an induction current flows through a detection coil of a detection circuit 7 of the dummy ring 14. When a screwed surface wears, a clearance delta occurs between the drive sleeve 1 and the valve shaft 2. As the impedance on the side of the detection coil changes according to the degree of the clearance delta, the change in the impedance is sensed on the side of the output coil.
