Title: Two-dimensional solid-state image pickup device
Inventor: NISHIZAWA JIYUNICHI
IPC: H04N5/335
Filed: 1983-02-22
Abstract: PURPOSE:To refresh picture element cells at each horizontal blanking period by connecting plural selecting lines to a refreshing vertical scanning circuit in a two-dimensional solid-state image pickup device comprising electrostatic induction transistors(TRs). CONSTITUTION:Picture element cells 1-1-m-1...1-n-m-n comprising the electrostatic induction TRs are connected to signal read lines 16-1-16-n and selecting lines 13-1-13-m to constitute the two-dimensional picture element cells. The read lines 16-1-16-n are connected to an output line 17 via switch SW TRs 11-1-11-n, which are selected by a horizontal scanning circuit 62. The selecting lines 13-1-13-m are connected to a readout vertical scanning circuit 63 via SW TRs 60-1-60-m turned on during the horizontal scanning period. Further, the selecting lines 13-1-13-m are connected to a refreshing vertical scanning circuit 64 via SW TRs 61-1-61-m turned on during the horizontal blanking period and turned off during the horizontal scanning period. Thus, a picture signal for the cells 1-1-m-n is read at the horizontal scanning period and refreshed during the horizontal blanking period.

Title: Pattern display unit
Inventor: KAWASAKI ITARU
IPC: G09G5/32
Filed: 1978-03-08
Abstract: PURPOSE:To secure the pattern display of a high degree of freedom by securing the display of each pattern position at the free area without being fixed with every minor section and thus ensuring the inter-character and inter-sentence selection to the easy-to-read arrangement pitch. CONSTITUTION:Picture position processor 3 performs the positional process for the picture pattern on CRT, and pattern memory 6 memorizes plural units of the picture pattern whose horizontal direction comprises S-units of dot and delivers S-units of dot with input of the pattern code corresponding to each picture pattern. In addition to these units, pattern disignation memory 4 is provided to the address corresponding to each picture section standard position on CRT to memorize the blank code corresponding to the blank code as well as the pattern code corresponding to the picture pattern in the form of the data. Then the arithmetic result of processor 3 is written into memory 4, and at the same time the data of memory 4 corresponding to the scanning line position on CRT through pattern designation sequence reader 5. Thus, the pattern display becomes possible with a high degree of freedom.

Title: Brushless motor for fan
Inventor: KAWAMOTO TETSUO
IPC: H02K5/18
Filed: 1991-02-21
Abstract: PURPOSE:To obtain a small and high output brushless motor for fan, in which driving circuit can be cooled efficiently, by feeding the air flow produced through rotation of fan to the fan and the heating source of the driving circuit, i.e., a power element. CONSTITUTION:A brushless motor is contained in a casing 16 comprising upper and lower semicylindrical bodies 17, 18. The semicylindrical bodies 17, 18 and a motor casing 8 constitute an air flow path. A fan 15 rotates as the rotor 1 rotates and thus produced air flow takes away heat from heat dissipation fins 8a, 8a. Since heat is also taken away from a power element 14f in a drive circuit 14, heat dissipation performance is further improved resulting in high output with reduced size. Furthermore, since the drive circuit can be disposed closely to a stator or a magnetic sensitive element, electrical connection is facilitated resulting in reduction of size and enhancement of workability in assemblage.

Abstract: PURPOSE:To prevent a characteristic of this capacitor from being deteriorated during formation and to lower the cost by a method wherein a dielectric ceramic layer is constituted of a material which contains a nonreducing dielectric powder and a low.-temperature sintering auxiliary agent and an internal electrode is formed of copper or a copper alloy. CONSTITUTION:The following are installed; a plurality of dielectric ceramic layers 14; a plurality of internal electrodes 16 formed between the dielectric ceramic layers 14 in such a way that their respective end edges are exposed alternately at both end faces of the dielectric ceramic layers 14; external electrodes 18 connected to the exposed internal electrodes 16 at both end faces of the dielectric ceramic layers 14. The dielectric ceramic layers 14 are constituted of a material which contains a nonreducing dielectric powder and a low- temperature sintering auxiliary agent; the internal electrodes 16 are formed of copper or a copper alloy. Thereby, they can be baked at a low temperature without deteriorating their characteristic even in a reduction rich atmosphere; their baking cost and material cost can be lowered.

Title: Method for producing wiring board to be subjected to wire bonding
Inventor: SHIBATA TAKAHIRO
IPC: H01L21/60
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To obviate the occurrence of peeling between a nickel-phosphorus alloy layer and a gold layer which is the front layer of a wiring board when the gold layer is subjected to wire bonding. SOLUTION: A metallized metallic layer 3 is integrally formed on an insulating substrate 2 and the nickel-boron alloy layer 4 is deposited and formed thereon by reduction electroless plating. The nickel-phosphorus alloy layer 5 is then deposited and formed thereon by reduction electroless plating. Sintering is executed at 600 to 700 deg.C and thereafter, the first gold layer 6a of the gold layer 6 is deposited and formed by the displacement electroless gold plating and further, the second gold layer 6 6b of the gold layer 6 is deposited and formed by the displacement electroless gold plating. The occurrence of peeling between the nickel-phosphorus alloy layer 5 and the gold layer 6 is averted when the gold layer 6 which is the surface layer of a package body 1 for electronic parts is subjected to wire bonding.

Title: Camera with focus detector
Inventor: KUSAKA YOSUKE
IPC: G02B7/34
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To accurately detect information related to the brightness of an object by inhibiting the detection operation of information related to the brightness of the object in the period when a pupil division means alternately opens and closes first and second apertures. SOLUTION: An operation means 5 not only intercepts light in parts other than apertures of a pupil division means 3 but also alternately opens and closes a pair of apertures in time division. A photoelectric conversion means 4 outputs a picture signal for opening of one aperture and a picture signal for opening of the other synchronously with alternate time-division opening and closing of the pair of apertures. A photometric means 27 cannot accurately measure light in the middle of operation of the pupil division means 3 because a luminous flux is limited by the pupil division means 3. Then, the operation means 5 inhibits the photometric operation of the photometric means 27 while the pupil division means 3 is operated. When the pupil division means 3 enters into the full release state, the photometric means 27 starts detection of information related to the brightness of the object.

Title: Operation device to stop engine
Inventor: KAWAI ISAMU
IPC: F02D11/04
Filed: 1979-03-07
Abstract: PURPOSE: To devise a perfect prevention from forgetting to cut off a main switch by providing the operation part of an engine-stop operation mechanism almost at the same spot with a main swtich, and interlocking the engine-stop operation by the operation part with the off-operation of a main switch.  
     CONSTITUTION: When an engine 2 is stopped for getting off a car, the engine 2 is brought into idling by operating a speed regulation lever 23 via a handle accelerator lever 25. Subsequently, when an operation part 16 of an engine-stop operation mechanism is pushed forward, a stop lever 10 can be operated to be turned backward through an interlocking link 13 and a stop rod 12 for stopping the engine 2. At this stage, by the pushing operation of the operation part 16, the top part of an interlocking part 20 rotates a rotation part 9 anticlockwise as sliding from the rear end to the front end on the interlocked part 22, and gives an off-operation to a main switch 6. Consequently, the main switch 6 can be off as soon as the engine is stopped.
