Title: Thyristor with overvoltage protective function
Inventor: YAMAGUCHI YOSHIHIRO
IPC: H01L29/74
Filed: 1983-11-15
Abstract: PURPOSE:To enable to realize the titled thyristor posessing a higher resistivity of di/dt, which can be safely turned to ON and OFF against impression of overvoltage without damaging the resistivity of dv/dt of the first pilot thyristor, by a method wherein a breakdown voltage region, whose forward stopping voltage is lower than that of other regions, is provided at the inner peripheral part of the first pilot thyristor. CONSTITUTION:Breakdown current to generate by breakdown voltage runs to the lateral direction of the P type layer 23 of a first pilot thyristor PT1, and after the breakdown current ran through collectors 25 provided on the P type base layer 23, the breakdown current runs in a cathode electrdoe 37 through short-circuit parts 39 provided between the P type base layer 23 and the cathode electrode 37. As a result, the breakdown current makes a potential difference generate to the lateral resistance of the P type base layer 23 of the PT1 region and the N type emitter layer 24a of the PT1 is biased in the forward direction. When the value of voltage biased in the forward direction approaches the diffusion potential value of the junction part between the N type emitter layer 24a and the base layer 23, the injection of electrons, which are injected from the N type emitter layer 24a, is abruptly increased an the PT1 is turned-ON to overvoltage. This ON-state current of the PT1 runs to the P type base layer 32 of a second pilot thyristor PT2 as gate current through wirings 36 and the PT2 is made to turn-ON.

IPC: H04W84/02
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To provide the data receiver that clearly manages an expiration date of an information service and simplifies customer management. SOLUTION: At application of power, first a time counted by an internal clock 13 is corrected according to time correction data included in a paging signal sent from an information server.

And when the extended number of times exceeds the count number of times, valid/invalid information is set to be invalid and the reception of the information service is stopped. On the other hand, when the extended number of times is not in excess of the count number, the next period is extended by a cycle period.

Filed: 1986-09-16
Abstract: PURPOSE:To reduce the size and to improve the performance by a method wherein a bipolar transistor is isolated by a groove and an emitter region and a base region of the bipolar transistor are formed in a self-aligned manner in relation to said groove. CONSTITUTION:E.g. an n<-> type silicon epitaxial layer 3 is formed on a semicon ductor substrate 1. A groove 4 whose cross section is U-shaped is made inside the silicon epitaxial layer 3 and the semiconductor substrate 1. In one region surrounded by this groove 4, e.g. a p-type base region 7 and e.g. an n<+> type emitter region 8 are formed in a self-aligned manner in relation to this groove 4. A collector region is composed of the silicon epitaxial layer 3 located below the base region 7. Through this constitution, it is not required to align a photomask which is used to form the emitter region 8 and the base region 7 in relation to the region for device isolation. It is, therefore, possible to reduce the size of a bipolar transistor and to improve the electrical characteristic of the transistor.

Filed: 1993-08-31
Abstract: PURPOSE: To obtain an image inside the head easily by arranging one pair of solenoid coils of zero pitch for the orthogonal phase detection in a helmet surrounding the head part of a patient in order to couple an MRI-RF signal. CONSTITUTION: Crossing phase detection is carried out by means of MRI by accommodating a head part 102 of a patient. A condition of the head 102 is checked from a gap 202 of a transparent window 200. There is arranged one pair of solenoid wires L10, L20 with zero pitch. Turned parts of respective wires connect dog legs. The turn parts are connected in series along a surface of a solenoid within an area extending in a preset axial direction. Returning coils minimize an area of equal returning loops, thus coupling by means of the returning loops are minimized. Furthermore, loops for crossing phase detection are directed mainly for coupling to a magnetic field orthogonally crossing a main magnetic field. Thereby, an MRI image within the head of the patient can be obtained correctly.
