Patent JP-S60106281-A (JP)
Title: Interphone device with television
Inventor: SUZUKI HISANORI
IPC: H04M9/00
Filed: 1983-11-15
Abstract: PURPOSE:To increase the lifetime of an imge pickup tube by applying the rated voltage to the pickup tube instead of the voltage lower than the rated voltage only in case a call is given from a slave device. CONSTITUTION:When a detection signal is supplied to an input terminal (a) in a master device B through a call detection circuit, a talking detecting circuit, etc., a fixed current flows to a relay RY within a slave device A. Therefore a relay contact RYa1 is closed with a contact RYa2 switched respectively. Then the output of a constant voltage circuit E2 is applied directly to the heater and the grid of an image pickup tube V with no intervention of a resistance R8 and a VR1. In other words, the rated voltage is applied to an image pickup tube instead of the voltge lower than the rated voltage. This increases the lifetime of the image pickup tube.

Title: Device for estimating position of abnormality happening of distributing water pipe net
Inventor: TSUKIYAMA MAKOTO
IPC: G01M3/28
Filed: 1984-10-15
Abstract: PURPOSE:To detect abnormality of a pipe conduit the moment it happens by providing a device for calculating measured value variation vector outputting a sudden change coming out on an online pressure measuring instrument in process of measuring as a calculation vector when the abnormality happens in a distributing water pipe net. CONSTITUTION:The pressure measuring instrument 2 measures a joint of the distributing water pipe net 1 for every sampling time. The distributing water pipe net 1 can be expressed mathematically by the continuity of the flow rate and characteristic relation between the flow rate and pressure at the joint and if an imaginary joint which does not exist actually is set on the pipe conduit at the time of this mathematical expressing, the outflow from this imaginary joint is zero. Since the happening of the abnormality can be expressed as a rapid increase of the outflow from the joint, when the outflow of the joint corresponding to the happening position is increased to investigate the influence of the abnormality happening on a mathematical model, a change between the simulated pressure before inceasing and the simulated pressure after increasing is an increased amount of the simulated pressure due to the abnormality and this increased amount can be calculated with the joint to which the measuring instrument 2 is provided.

Title: Laminated metallic gasket
Inventor: YOSHINO NOBUO
IPC: F02F11/00
Filed: 1987-08-29
Abstract: PURPOSE:To make the service life of a gasket longer by installing a compensating plate in the specified thickness interposingly between two substrates formed with a bead each, while setting up each bead of these substrates in symmetrical form to the compensating plate, and constituting a compensating part in a way of superposing a combustion chamber hole side peripheral edge of the compensating plate on another combustion chamber hole side peripheral edge of a turnup substrate. CONSTITUTION:Thickness H of a compensating part 18 is larger than thickness (h), superposing a first substrate 4, a second substrate 6 and a compensating plate 8 all on one another, and that it is formed to compensate a space S on a deck surface to be produced around a combustion chamber 30 when a cylinder head 22 and a cylinder block 24 are clamped by a clamping bolt 28. That is to say, at this compensating part 18, it is formed to be thicker than the thickness (h) as much as a portion of thickness (c) of a compensating peripheral edge 8e of the compensating plate 8. With this constitution, the space S on the deck surface around the combustion chamber 30 is surely compensated, while uniform sealing pressure is made to act on the whole deck surface by the compensating plate 8 with the specified thickness (c). Accordingly, bashes on beads 14, 16 due to explosive power are prevented from occurring so that application life is thus prolonged.

Title: Automatic stamping device
Inventor: MORI GORO
IPC: G03G15/00
Filed: 1984-10-15
Abstract: PURPOSE:To prevent stopping position deviation by utilizing a motor, as a pulse motor, which rotates a rotation member which supports a printing surface. CONSTITUTION:A pulse motor 520 is synchronized with a pulse of an encoder 730 and is energized for its rotation in normal direction, starting counting of volume of rotation of the motor. When a driving volume reaches a fixed value PV, the printing surface comes immediately before the roller 572, therefore, an electricity is applied to a solenoid and the roller 572 is lifted, starting stamping accordingly. Energizing of motor 520 is continued for rotation in its normal direction thereafter, and if a sensor 536 is shaded, a printing tool returns to the home position, stopping the motor 520 and turning off the solenoid 578; and a locking electrical current of the level lower than the energizing electricity for rotation is applied to the motor 520. Thus, the rotation member is stopped and locked at its home position, and a position deviation is prevented.

IPC: G11B19/06
Filed: 1991-08-02
Abstract: PURPOSE:To prevent damage, etc., of jackets, to easily and surely select disk music and to facilitate correspondence between disks and jackets. CONSTITUTION:The index of music is recorded for example in chapter zero, which is a leading chapter of a disk 1, as one frame for one round, and the still reproduction of the index is performed while standing by for the play of the music. Consequently, in the case of selecting music, the confirmation of the music by means of the jacket, index, etc., is no longer necessary. Therefore, scrambling for the jacket by many people is eliminated, and even when the jacket is lost, there is no need to take out the disk that is being played or standing by each time since a need to confirm the label of the disk is eliminated. Furthermore, even when the number of disks is increased, the confirmation of the labels of the disks is not necessary; and while checking the state of the still reproduction of the index, combination with jackets can be dealt with.
