Title: Cylindrical piezoelectric ceramic element
Inventor: TAKAHASHI SADAYUKI
IPC: H01L41/09
Filed: 1984-07-13
Abstract: PURPOSE:To obtain a clamp element which can be driven with a low voltage and produced at a low cost and with high productivity, by providing a plurality of internal electrodes in the axial direction of the cylinder at predetermined spaces with piezoelectric ceramics interposed therebetween; connecting every second layer of the internal electrodes with external electrodes on both end faces of the cylindrical element; and providing an insulator on the inner and outer peripheral surfaces of the element. CONSTITUTION:A plurality of piezoelectric ceramics elements are layered with internal electrodes 6 interposed therebetween to form an integral element. The internal electrode layers exposed on the end faces of the element are covered with insulators 8 at every second layer. External electrodes 9 are provided thereon to electrically connect the internal electrode layers in parallel with each other. The ceramics portions are polarized in the directions indicated by the arrows. When a voltage is applied between the external electrodes so as to accelerate the polarization, the ceramics are extended circumferentially of the cylindrical element, accordingly in the radial direction, proportionally to the magnitude of the applied voltage. The smaller the space between the internal electrodes is, the more approximates the shape of the ceramics between two internal electrodes to a rectangular parallelepiped, and therefore the more uniformized is internal field strength of the ceramics is. Thus, the longitudinal effect strain is uniformized, and a cylindrical laminated piezoelectric ceramics element can be obtained with high reliability.

Title: Reciprocating motion guide device
Inventor: TERAMACHI HIROSHI
IPC: F16H25/22
Filed: 1987-06-11
Abstract: PURPOSE:To lightly carry out reciprocating motion without causing a shaft to rotate by using said shaft in which a spline groove is superposed with a screw groove in the same zone in a reciprocating motion guide device used for the arm of an industrial robot, etc. CONSTITUTION:As a motor M is rotated, a ball-screw nut 6 is rotated via gears 28, 29 to convert the rotation of the motor M into the reciprocating motion of a shaft 4 via a ball screw groove 2. Since a ball-spline outer cylinder 7 which is fitted in a ball-spline groove 3 is keyed and is in a fixed condition in the rotating direction, the shaft 4 is guided by the spline groove 3 and reciprocated without rotating. Balls 5 which are interposed in between the ball-spline outer cylinder 7 and the shaft 4 are guided and held by a holding device 12. Thus, since the shaft 4 is prevented from rotating by means of the outer cylinder 7, the transfer of an object which is loaded on the end of the shaft 4 can be stably carried out, while also enabling the loading of even a lopsided load.

Title: Roller conveyor
Inventor: HATOUCHI GOKICHI
IPC: B65G13/071
Filed: 1990-06-04
Abstract: PURPOSE:To make the whole size of a roller conveyor compact and maintain a power transmission part continuously in the constant state by providing a deflectable body to be in and out of contact with a roller by expansion/contraction, and also a fluid supply/discharge passage opened into the deflectable body from a supporting shaft through a cylinder member. CONSTITUTION:A solenoid valve 96 is switched over to connect an air supply hose 98 to a supply/discharge hose 95, and a rubber tube 70 is expanded under the pressure of air supplied from a fluid supply/discharge passage 73 to bring a contact part 70d into contact with the lower part of a roller 31. At this time, a chain 41 is continuously driven by a motor 45, so that a cylinder member 68 is rotated around a supporting shaft 66 through a sprocket 69 engaged with the chain 41. Further because of the tube 70, rotated integrally with the cylinder member 68, being in contact with the roller 31, the roller 31 is also forced to be rotated integrally, and thus a pallet 48 is conveyed. When the solenoid valve 96 is switch to cut off the hose 95 from the hose 98, pressure in the tube 70 is released, so that the contact part 70d moves inside by the elastic force of an elastic part 70c and is separated from the lower part of the roller 31. The forced rotation of the roller 31 is not therefore generated, and thus the conveyance is stopped.

Title: Optical recording medium
Inventor: TAKAHASHI MASAHIKO
IPC: G11B7/24
Filed: 1990-06-06
Abstract: PURPOSE:To obtain an always specified recording sensitivity by using a material having the temp. characteristics of a thermal conductivity as an underlying layer or protective layer or intermediate layer. CONSTITUTION:If the thin film of such a material which has the small thermal conductivity at room temp. and has the thermal conductivity increasing with an increase in temp. is provided in contact with a recording film, the thermal conductivity of the underlying layer is larger on the inner periphery where the temp. rise is larger and, therefore, the heat generated in the recording film is rapidly transferred to the underlying layer and the temp. rise of the recording film itself decreases. On the other hand, the thermal conductivity of the underlying layer is smaller on the outer periphery where the temp. rise is smaller an, therefore, the heat generated in the recording film is hardly transferred to the underlying layer. The recording sensitivity nearly constant over the entire surface of the disk is obtd. in this way.

Title: Circuit and method for detection of reactive clock signal
Inventor: RANII ERU PAAKAA
IPC: H04L7/033
Filed: 1992-05-12
Abstract: PURPOSE: To monitor the frequency of an input clock signal and to detect an invalid clock signal based on its deviation from a reference signal. CONSTITUTION: A phase locked loop(PLL) monitors the frequencies of redundant and input clock signals and when one or the other gets invalid, these signals are switched. Therefore, even when one input clock signal is turned faulty, a PLL 10 continues the normal operation. When two input clock signals 1 and 2 are turned faulty, until any one input clock signal is recovered, an internal reference signal maintains the PLL 10 in a nominal operating frequency and the loop quickly re-establishes the phase lock. In order to discriminate validity, the input clock signal is sampled and stored by the reference signal through a prescribed method.  When the sample values of respective input clock signals after a sample period have the same logic state, these input clock signals are valid but when one of sample of input clock signals after the sample period has a different logic state at least, the input clock signal is invalid.
