Title: Leased circuit backup device
Inventor: OGAWA YASUYUKI
IPC: H04Q3/00
Filed: 1984-12-07
Abstract: PURPOSE:To make a circuit selecting control information transmitting part of a center side backup device unnecessary by measuring the time required for detecting an incoming of a calling signal to a terminal side from a center, converting this time to circuit selecting control information, and switching one circuit of a leased circuit to two circuits of an exchange by this control information. CONSTITUTION:In case a fault is generated in leased circuits 7-9, relays 6a, 6b of an exchange circuit switching part 6 of a center side backup device 1 are switched to the side of telephone sets 3, 4 respectively. Subsequently, a switching control part 15 of a terminal side backup device 12 is called by the telephone set 3. The control part 15 detects an incoming of a calling signal of the center, returns a calling signal incoming confirming tone and starts a time counting. Subsequently, the same operation is executed by the telephone set 4, and the time counting of the control part 15 is stopped. In case of a fault of the circuit 7, a switching part of the leased circuit 7 of a terminal side leased circuit switching part 14 is switched to an exchange side by the control part 15. The center switches a switching part of the leased circuit 7 of a leased circuit switching part 5, to a switching part 6 side, and also switches the switching part 6 to the leased circuit switching part 5 side.

Title: Manufacture of semiconductor device
Inventor: FUKUDA TADASHI
IPC: H01L21/316
Filed: 1987-10-14
Abstract: PURPOSE:To decrease a width of a field oxide film for realizing a highly integrated semiconductor, IC, by selectively oxidizing a silicon carbide pattern with a mask resistive to oxidation so that the field oxide film thus formed has a part buried in a semiconductor substrate, said part having approximately vertical end faces. CONSTITUTION:Using a resist film pattern as a mask, an Si3N4 film 7, a CVD- SiO2 film 6 and an SiC layer 5 are patterned sequentially to provide first and second SiC layer patterns 5A and 5B. Then, using these SiC layer patterns 5A and 5B as a mask, an ordinary selective oxidation process is carried out. On the surface of an n-type collector region 3 thus exposed, a first Selectively oxidized film 8 is formed such that its bottom is rooted in the n-type collector region 3. This process can be performed without the selectively oxidized film 8 penetrating into the interface between the SiC layer, patterns 5A, 5B and the n-type collector region 3 like a bird's beak, and the end face E1 of the first selectively oxidized film 8 contacted with the lower regions of the SiC layer patterns 5A and 5B can be formed approximately vertical. Thus, the base region and the collector contact region can be designed in a small area without any margin and a highly integrated element can be realized.

Title: Electronic blackboard
Inventor: SUZUKI TETSUYA
IPC: H04N1/00
Filed: 1989-10-05
Abstract: PURPOSE:To improve the convenience of use of an electronic blackboard by adding/subtracting a revised value to/from an initial size of writing board so as to calculate the size of the writing board after the revision when the size of the writing board is revised after the initial size of the writing board is calculated. CONSTITUTION:The size of a writing area 20 formed between two frames 11, 12 varies from a minimum area shown in caption 20a in Figure (A) into a maximum area shown in caption 20b in Figure (B). That is, the size of the writing area is variable by a 1st and 2nd frames 11, 12. When an electronic blackboard is set to the initial state, that is, started, the size of the writing area set at that time is obtained and when the size of the writing area is revised after some description is made onto the writing area, the revised area is obtained by adding/subtracting the revised value to the original size of the writing area. Thus, the size of the writing area after the revision is calculated and the operability of the electronic blackboard is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a focusing characteristic measuring device of an optical pickup and/or an optical disk, etc., capable of measuring the characteristic of a focusing state with high accuracy by a simple circuit. SOLUTION: An arithmetic processing part 12d controls an offset supplying circuit 23 and applys an offset voltage on a control signal of a focusing servo. The arithmetic processing part 12d detects the error rate of reproducing data in the state that the focal position of a laser beam is deviated by an offset amount. The arithmetic processing part 12d successively changes an offset voltage, repeats the processing and detects the error rate. The arithmetic processing part 12d approximates the relation of error rate to the offset amount by a quadratic curve. The offset amount having the smallest error rate is found from the approximated equation.

Filed: 1990-09-27
Abstract: PURPOSE:To prevent the generation of cracking of a high hardness metallic layer by forming a soft metallic layer having plural streaks at specified intervals of soft metal having higher elongation than that of high hardness metal on the surface of base material and performing cladding by welding by crossing the high hardness metal. CONSTITUTION:The soft metallic layer 2 is first formed on the surface of the base material 1 and the plural bars 3 are formed at the specified intervals on this soft metallic layer 2. Afterward, the high hardness metal is then clad by crossing the above-mentioned bars 3 and the high hardness metallic layer 3 is formed. At this time, cooling is started immediately after the high hardness metal is clad and heat stress in accordance with shrinkage is generated. However, the heat stress in the vertical direction and the heat stress in the horizontal direction are relaxed by the soft metallic layer 2 of the lower part of the soft metal and the bars 3 of the soft metallic layer, respectively. Accordingly, the generation of cracking of the high hardness metallic layer 3 can be prevented. In addition, since the whole surface of the base material is covered by the high hardness metallic layer 3, excellent wear resistance can be given.
