Title: Optical torque detecting device
Inventor: TANAKA KUNIYOSHI
IPC: G01L3/08
Filed: 1990-05-30
Abstract: PURPOSE:To widen the range of lighting to moire stripes and to widen the measurement range of the torque of a rotary shaft by lighting the moire stripes, which move in proportion to the torque of a rotary shaft, uniformly on the whole in its moving direction. CONSTITUTION:When the torque is applied to the rotary shaft 7, a torsion bar 3 twists in proportion to the rotary torque. When an inner cylinder holder 11 rotates at the same time, the moire stripes 13 move in the twisting direction. Namely, the inner cylinder holder 11 rotates in the twisting direction of the torsion bar 3 and then the moire stripes 13 move. Light from a line filament lamp 23 is converted by a lens 29 into parallel light, which transmitted through a part where the moire stripes 13 are not formed, reflected by a reflecting plate 31, and transmitted through the moire stripes 13 to project an image of the moire stripes 13 on a detection sensor 27. The obtained signal is processed to detect the torque from the movement quantity of the moire stripes. Thus, the lamp 23 is used to widen the lighting range and the parallel light is projected on the moire stripes, so the measurement width of the torque, i.e. dynamic range can be widened.

IPC: H04N1/32
Filed: 1979-10-29
Abstract: PURPOSE:To enable to confirm the transmitted code at the transmission side, by transmitting the identified code from the reception side and displaying it at the transmission side. CONSTITUTION:Protocol is made between the transmission and reception sides at the transmission, a mu-CPU1 reads out the isentification code at the transmission side from an ROMB10 and output is made from an MODEM interface 9 to an MODEM6. On the other hand, the identifying code is transmitted from the reception side and this is displayed on a display unit 12. Predetermined opposing codes are stored in an ROMB10 and the reception side code is stored in an RAMB11 at the same time with the communication time. The page counter of an RAMA3 is sequentially incremented at the transmission side every transmission of original for one sheet's share. At the last of communication, a mu-CPU1 moves the value of page counter of an RAMA3 to an RAMB 11 for storage. Since the facsimile operation like this is made while confirming the reception code of the display unit 12, the original can never be mistransmitted.

Abstract: PURPOSE: To readily set the low resonance frequency of a pickup to the best value by using the composite material of short fibers of silicon carbide fibers and a binding agent such as of synthetic resin, light metal, light metal alloy or other.  
     CONSTITUTION: Plural silicon carbide fibers 4 of about 8 to 10μ in diameter are made to short fibers of about 2 to 3mm. these are then mixed in a thermosetting resin such as epoxy resin 5 or the like by desired mixing ratio and are heat- and pressure-molded to a desired shape, e.g., a head shell 7 of a section L type having a cartridge mounting part 7a provided with holes 6 for mounting of a pickup cartridge and an arm mounting part 7b mounted with the output line junction connector of the cartridge and mounted to the pickup arm. Since the head shell formed thereby is of a small specific gravity and high rigidity, its low resonance frequency may be readily set at around 10Hz and since it has large internal loss, it permits the improvement of vibration attenuation characteristics and the enhancement of the transient characteristics of the pickup.

Title: Gas laser generating device
Inventor: SUZUKI MINORU
IPC: H01S3/097
Filed: 1987-06-05
Abstract: PURPOSE:To enable an electrical energy necessary for the laser oscillation to decrease by a method wherein an auxiliary electrode is provided to the outside of a discharge tube on one primary electrode side and the auxiliary electrode is connected to the same potential as the other primary electrode. CONSTITUTION:One primary electrode 2 inside a discharge tube 1 and an auxiliary electrode 4 outside the discharge tube 1 are arranged facing toward each other, and the auxiliary electrode 4 is connected so as to be the same potential as the other primary electrode 3. As a discharge power source voltage V makes the voltage increase drastically before a glow discharge starts, the voltage change with time (dv/dt) is large, but once the discharge starts, the voltage becomes constant, which is a glow discharge voltage, so that dv/dt is made small. The auxiliary electrode 4 is separated from the primary electrodes 2 and 3 by the wall of the discharge tube 1 and the impedance between them is an electrostatic capacitance, wherefore an auxiliary current is supplied only when dv/dt is large. As mentioned above, an auxiliary current is made to flow between the primary electrodes 2 and 3 and the auxiliary electrode 4 when the discharge starts, so that a power consumption is decreased.
