IPC: G11B15/68
Filed: 1984-04-03
Abstract: PURPOSE:To cope quickly with a fault or the urgent insertion and addition of reproduction transmission by using the rest ones of plural producers based on the storage contents of a memory means which stores the desired number of reproducers that are designated as the spare reproducers among those reproduces. CONSTITUTION:An automatic tape cassette supply selection reproducer M uses all VTR81-84 and usually uses three of these four VTRs with a remaining VTR defined as a spare VTR. This spare VTR is used in case either one of three VTRs has a fault or the transmission numbers are interrupted. When the VTR84, for example, is designated as a spare one, the rest VTR81-83 are usually used. At the same time, a memory means 50 stores that the VTR84 is defined as a spare one. If the VTR83, for example, has a fault, this VTR83 is replaced with the spare VTR84 under the control of a control means 24. Then this replacement is stored to the means 50.

Abstract: PURPOSE:To prevent the fracture of a pin made of a shape material to be provided to a die for die casting as a result of repeated die casting, by subjecting said pin to a surface hardening treatment then coating any among TiC, and ZnC thereon by a PVD method. CONSTITUTION:A die casting pin 4 provided so as to project from a bottom die 1 of a die for die casting consisting of a top die 2 and the bottom die 1 is made of a shape material such as SKD 61 similarly to the top and bottom dies.

Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an optical element switch device where the occurrence of a shock is prevented and heat generation is suppressed at the time of switching an optical element by driving the movement of a moving member by a motor and converting a rotary operation into a linear operation during a driving transmission route to the moving member. SOLUTION: When a crank 8 rotates with the rotary shaft 91 of a pulse motor 9 as the center, a roller 7 moves in an oblong hole 62 of a plate 6 while it turns in the longitudinal direction. Since a balancer is installed in the other end part of the crank 8, the balance of the crank 8 is kept with the rotary shaft 91 of the pulse motor 9 as the center. A straight line connecting the center of the roller 7 at one end part of the crank 8 and the center of the rotary shaft 91 of the pulse motor 9 becomes parallel to a direction where a moving block 3 moves Namely, since power is supplied to the pulse motor 9 only when a prism 1 and a prism 2 are switched, the rise of the temperature of the pulse motor 9 can be suppressed to be low.

IPC: G01B21/00
Filed: 1994-03-11
Abstract: PURPOSE:To output a position detection signal at a desired timing at any cycle of a requiring signal, by detecting the cycle of the signal requiring a detection value from an external system, determining a timing of a position detection instruction based on the data and outputting the position detection signal with the timing. CONSTITUTION:A microcomputer 21 decides whether or not a detection value- requiring signal DRQ is a first one when the signal is input. If the signal is the first one, the time is read and preserved. The microcomputer 21 then waits for a signal DRQ to be input again. Although an interpolation process is root indispensable at the first time, the process result can be utilized to calculate a velocity for the next time, etc., if the interpolation is carried out, from the first time. When the signal DRQ is input, for the second time and afterwards, the time is read and a displacement detection value Pb detected immediately before the signal DRQ is input is output to a serial communication interface 22. The interface 22 outputs the input displacement detection value Pb in the form of serial data TXD to an external system 31.
