Title: Machining shape display in electric discharge machining
Inventor: SAKAGAMI MAKOTO
IPC: B23Q17/00
Filed: 1985-04-05
Abstract: PURPOSE:To make the machining shape easily understood by an operator by displaying the machining shape on a Braun tube using machining shape data of top, bottom and speed command surface of a work derived from a program for numerical control in an electric discharge machining. CONSTITUTION:When a positioning command (X, U)=(X0, U0) is issued from a controller of an electric discharge machine, a wire 16 lies as shown in the figure. Since the coordinates required for graphic display are abscissas X1-X3 of the bottom plane (Z1+Z4 plane), top plane (Z4+Z5 plane) and machining speed command plane (Z2+Z4 plane) of the work 27 respectively, X1-X3 are derived from the values of X0 and U0. Therefore, after decoding a program for numerical control, machining handling routine in the machining program is called. From the obtained values of X, Y, Z, U, V, data required for graphics are derived to display the machining shape contour on the Braun tube of the display unit where each program for NC is 3-dimensionally checked.

Title: Multi step powder molding press
Inventor: KATAGIRI TAKESHI
IPC: B30B11/02
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent the crack with a proportional pressing method by positioning a punch, using a pressurizing end position stopper at the pressurizing end position. A control device of a fluid cylinder, which drives a movable punch corresponding to the dimension rate of each step part of a molding product, is installed, and the maximum pressure of the fluid pressure cylinder is set smaller than the final molding pressure. SOLUTION: In the case of the first powder part 591, an upper first punch 7 is pressurized by an upper ram against a bottom first punch 27 fixed. The second powder part 592 is pressurized by an upper second punch 8 and a bottom second punch while the upper and bottom second oil pressure cylinders are controlled to equalize the condensation with that of the first powder part 591. The third powder part 593 is controlled and pressurized in the same way. The upper second, bottom second, upper third, and bottom third oil pressure cylinders are controlled so that the lowering speed of the related upper and bottom punches satisfies a given rate relation against the dimension of each step part with respect to the bottom face of the first step part W1 of a molding product W as a basis.  Thus the 1st-3rd powder parts 591-593 have the same condensation, so the powder does not move to each other and the crack is prevented.

Filed: 1987-03-27
Abstract: PURPOSE:To position a semiconductor wafer by setting the orientation flat part of the wafer to a designated position by a calculation based on information from a noncontact sensor obtained by rotating one revolution the wafer. CONSTITUTION:When a semiconductor wafer 1 is contacted with a stopper 5, a motor 16 is stopped, a chuck 3 is raised, the stopper 5 is operated rightward of this paper, a pressure reducing unit 15 is further operated to scrape up the wafer 1 from a round belt 10, the chuck is then stopped, a pulse motor 6 is then rotated one revolution and stopped.

Title: Video disk player
Inventor: WATABE HIROSHI
IPC: G11B19/28
Filed: 1989-03-22
Abstract: PURPOSE:To discriminate the recording system of a video disk record with high efficiency in a process to increase the rotation of the disk record by identifying a reproducing signal in the neighborhood of the recording start point of the video disk record with constant angular velocity. CONSTITUTION:A recording system discrimination circuit 18, when discriminating the video disk record with constant linear velocity, inputs discriminated output to a disk servo circuit 7 and an access servo circuit 8. Therefore, the disk servo circuit 7 increases the rotating speed of the disk record D compulsively, and the access servo circuit 8 drives a pickup motor 4 on a pickup movable carriage. As a result, a pickup reproduces the video disk record with the constant linear velocity starting from the recording start point. Furthermore, when the recording system discrimination circuit 18 discriminates the video disk record with the constant angular velocity, reproduction from the recording start point can be performed by continuing the reproduction successively. In such a way, it is possible to discriminate the recording system of the disk record with high accuracy in the process to increase the rotation of the disk record.

A piezoelectric substrate 50 used for the voltage controlled oscillator is constituted of a buffer layer 52, a PZT thin film 53 and an Al electrode 54 on a Si substrate with oxide film 51. Since the voltage control oscillator incorporating a piezoelectric resonator can monolithically be manufactured in the semiconductor circuit of IC and the like, the resonator can be miniaturized. Thus, the voltage controlled oscillator which covers the frequency of the considerably large band and which is superior in an SN ratio can be obtained by using the PZT thin film or the PT thin film having a large electric machine connection coefficient and a superior Q characteristic.

Abstract: PURPOSE:To obtain an air conditioner for vehicle that can alleviate deceleration shock of the vehicle generated when a compressor is operated. CONSTITUTION:When it is detected by an acceleration detection circuit in an engine control circuit 12 that a vehicle is accelerated, a signal for forcibly making the capacity of a variable capacity compressor 3 to a minimum level, is sent to a capacity controller 4 by an air conditioning control circuit 15. When the vehicle is sufficiently accelerated until an ATM 2 is shifted up, deceleration shock is generated on the vehicle due to the shifting up, and the capacity of the variable capacity compressor 3 is increased by the air conditioning control circuit 15 at the same time as the shifting up, so as to alleviate the deceleration shock. As for the amount to be increased, the car speed of the vehicle when it is shifted up, engine rotational number, and the capacity to be increased based on gear ratio, are calculated, and by sending a signal to the capacity controller 4 so that the amount of increase thus obtained is increased in the capacity, the shock felt by a passenger will be constantly small.

All the speaker units 1 are driven at the same level in the same phase. Since the thickness of the sound absorbing members 4a, 4b or the sound absorbing member 5 provided to the front side of the speaker units is made thicker toward the circumferential part, a low frequency sound is sounded from all the speaker units 1 and a sound of higher frequency radiates from the center speaker units only. Thus, a strong weight function in the middle is applied to the sound of higher frequency, then the directivity speaker with a sharp directivity having a small side lobe over a broad frequency range is obtained.
