Title: Address conversion system
Inventor: WADA EIJI
IPC: G11C11/34
Filed: 1986-12-26
Abstract: PURPOSE:To switch conversion conditions in a short period by performing address conversion by using plural address conversion tables selectively, and registering different conversion conditions in respective address conversion tables previously. CONSTITUTION:An address signal A outputted by a pattern generation part 1 and a table select signal S are used as address information signals to access a random access memory 3. Therefore, information is read out of an address determined by the address signal A of one address conversion table 4 signified with the table select signal S and outputted from the random access memory 3 as an address signal B after address conversion. When address conversion conditions need to be switched, a central processing part 2 resets a table select signal S for signifying a necessary address conversion table 4 in a register 5. Consequently, the table select signal S is set in a short period and the interruption time of inspection for switching the address conversion conditions is extremely short.

Title: Remote control transmitter
Inventor: MURAKAMI TETSUO
IPC: H05K3/30
Filed: 1989-11-30
Abstract: PURPOSE:To offer a remote control transmitter being possible to test it in the state of completing a printed board by fixing beforehand a liquid crystal display panel alone on the printed board with a mounting bracket and by enabling the test of the transmitter in the step of a unit, i.e., in the state of completing the printed board and before incorporating it in an upper and a lower case. CONSTITUTION:A mounting bracket 14 can store a liquid crystal display panel 13 and a connector 16, and a leg 14a of the mounting bracket 14 is inserted into a rectangular hole 11a of a printed board 11. Then, the leg 14a protruding from the rectangular hole 11a is twirled and the liquid crystal display panel 13 is fixed singly on the printed board 11. Backlash between the printed board 11 and the mounting bracket 14 is prevented by absorbing the backlash corresponding to the tolerance through a taper 14b formed on the leg 14a at the time of torsional rotation. The liquid crystal display panel 14 can be mounted on the printed board 11 in a body, without using an upper and a lower case for holding the liquid crystal display panel as usual. Thereby, the liquid crystal display panel can be tested easily in the step of a unit, i.e., before incorporating it in the upper and lower case and can be replaced with another simply when failing.

Further, in the protecting extinguishing region, extinguishing liquid is discharged in a nearly conical-shaped injection pattern 35 from the injection heads 31-34. Accordingly, in the main extinguishing region, extinguishing liquid reaches a fire place without loosing the speed energy, and extinguishment is carried out speedily and surely. In the protecting extinguishing region, extinguishing liquid is injection-discharged so as to surround the main extinguishing region by the heads 31-34. Accordingly, the spreading of the fire to the periphery can be prevented.

Abstract: PURPOSE:To simplify the structure of a mannual valve by arranging the same such that it supplies oil to a first speed hold hydraulic clutch at a first speed retaining position thereof and connects a first oil path to a third oil path connected with the first speed hold hydraulic clutch. CONSTITUTION:A first speed retaining position of a mannual valve 9, communication to both a second oil path L12 to forward and reverse hydraulic clutch C4 and a first oil path L11 communicated with a specified shift valve 10 is disengaged, while the path L11 is connected to a third oil path L16 communicated with a first speed hold hydraulic clutch CH. A transmission system of higher step than the first step at the time of high speed running operation is established by the cooperation with other shift valves 101, 102 by controlling supplied and discharged oil, and a first speed transmission system is established by supplying oil to the clutch CH when the speed of vehicle is decreased. It is thus possible to simplify the structure of a mannual valve by composing the oil path additionally connected to the valve for supplying and discharging oil to the first speed hold hydraulic clutch of only the third oil path.

Filed: 1988-12-12
Abstract: PURPOSE:To lessen voltage rise of a lamp and decrease change in the light color by forming at least part of a current supplying element from a shape memory alloy, and thereby keeping the distance of a light emitting tube from the current supplying element amply after the lamp is completed. CONSTITUTION:A transparent light emitting tube 2 consisting of quartz, etc., having electrodes 3a, 3b at the ends is accommodated in a transparent outer tubing 1, and in its inside mercury or metal halide is encapsulated together with a gas such as argon or neon-argon for starting.

Title: Sputtering device and sputtering method using the same
Inventor: KAWAGUCHI TADAO
IPC: H01L21/203
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To allow deposition having an un-deposition region in the prescribed region on the surface of a work with a single apparatus and the deposition over the entire part of the surface by making a means for retaining the prescribed region of the surface of the supported work freely movable forward and backward of the surface of the work and fixable to an arbitrary position in the advancing and retreating directions. SOLUTION: If the un-deposition region is necessary at the end of the surface of a semiconductor substrate 1 supported by a substrate susceptor 2, a substrate retainer 4 is held at all times at the position shown by a broken line and the end of the surface of the semiconductor substrate 1 is retained as the un-deposition region and in this state the deposition treatment is executed without activating ejector pins 21.  On the other hand, if the entire part of the surface of the semiconductor substrate 1 is subjected to the deposition, an ejection driving cylinder 22 is driven to rise the ejector pins 21 during the deposition to push up the substrate retainer 4 to the position shown by a solid line, by which a clearance is generated between the semiconductor substrate 1 and the substrate retainer 4 to allow the film to infiltrate to the end on the surface of the semiconductor substrate 1 during the execution of the deposition treatment. The deposition over the entire part of the surface of the semiconductor substrate 1 is thus embodied.
