Title: Manufacture of composite vane for compressor
Inventor: OKUNO MICHIO
IPC: F04C18/356
Filed: 1989-02-20
Abstract: PURPOSE:To efficiently manufacture a composite vane having satisfactory adhesion with a wear-resistant member and a light-weighted member by polishing and cleaning each surface of the wear-resistant member and light-weighted member, and, after superheating, press-fitting these member to each other into the integrated form by a pair of hollow type rolls having different peripheral speeds. CONSTITUTION:A compressor composite vane 6 is formed of a wear resisting member 1 forming at least the center part of a sliding surface particularly requiring wear resistance, and a light-weighted member 2 forming other surfaces. In the manufacture of the composite vane 6, the respective surfaces of the wear-resistant member 1 and the light-weighted member 2 are first polished and cleaned. Then, the wear-resistant member 1 and the light-weighted member 2 are superheated to the respective determined temperatures, and then fed to a hollow type roll 5 formed of upper and lower rolls having different peripheral speeds to press-fit these members to each other into the integrated form. Hence, a lengthy product of the composite vane 6 having a satisfactory adhesion with the wear-resistant member 1 and the light-weighted member 2 is efficiently manufactured.

Title: Deceleration instructing point detection system for elevator
Inventor: MIURA MORIYUKI
IPC: B66B1/50
Filed: 1978-04-05
Abstract: PURPOSE: To improve the maintenance property and the accuracy of detection of position, by using a pulse counter.  
     CONSTITUTION: A perforated tape 13 is provided in an elevator duct in the moving direction of a gondola 8 and a proximity switch 15 is attached to the donlola so that a pulse generator is formed. The pulse generator is connected to a microcomputer 20 through a buffer register 17, an updown counter 18 and input/output  regiters 19a, 19c. When a perforated hole 14 is detected by the proximity switch 15,  a pulse is generated. The pulse is added to the content of the updown counter 18 when the gondola is moving up. The pulse is stored into an input/output register 19b when the gondola is moving down. A central processing unit 23 compares data in a read-only memory 21 with the number of pulses stored in the register 19 and corresponding to the position of the gondola to apply a deceleration instructing signal 27 to a driving unit when the gondola can be decelerated and stopped. Therefore, the number of mechanical contacts for switching is greatly reduced and the accuracy of detection of the position depends on the spacing between the perforated holes 14.

Abstract: PURPOSE:To improve operability by setting a correction value as the minimum Y coordinate value in case of designating partial print image display by a designation means, and performing the partial print image display behind a row designated by a cursor. CONSTITUTION:The display picture number of the row designated by the cursor is calculated, and the minimum Y coordinate value and the maximum Y coordinate value are calculated from a calculated display picture number, and for example, when the display picture number is a first picture, the minimum Y coordinate value and the maximum Y coordinate value as shown in figure are calculated. When a partial print image is selected, the row to which the cursor belongs is designated as the minimum Y coordinate value, and the frame of document size is displayed on a display unit, and only the range within from the minimum Y coordinate value to the maximum Y coordinate value is displayed compressively. In such a way, since the partial print image behind the row designated by the cursor can be displayed, it is possible to display a print image from a designated row immediately, thereby, the operability can be improved.

IPC: H04N5/52
Filed: 1988-02-25
Abstract: PURPOSE:To eliminate ghost surely by comparing the quantity of a positive threshold value, a negative threshold value, and a prescribed tap gain of a transversal filter, decreasing the attenuation of the attenuation means when the tap gain is larger than the positive threshold value and increasing the attenuation of the attenuation means when the tap gain is smaller than the negative threshold value. CONSTITUTION:A comparator circuit 21 supplies a pulse of high level to a set terminal S of a flip-flop circuit 23 when the main tap gain C0 is larger than the positive threshold value A1. Moreover, a comparator circuit 22 supplies a pulse of high level to a reset terminal R of the flip-flop circuit 23 when the main tap gain C0 is smaller than the negative threshold value A2. A Q output of the flip-flop circuit 23 is supplied as a control signal of attenuation to a variable attenuator 13. The attenuation of the variable attenautor 13 is set to a small value when the Q output of the flip-flop circuit 23 is at a high level and when the Q output is at a low level, the attenuation is set to a large value. Thus, even a large negative ghost is surely eliminated and the dynamic range of an A/D conversion circuit is effectively utilized.

Title: Insulating paste composition
Inventor: FUKAI MOTOHARU
IPC: H01G4/12
Filed: 1989-02-20
Abstract: PURPOSE:To enable a ceramic compact to be calcined without an insulating paste composition being left on the surface of the substrate, without causing expansion of a width of a low dielectric constant region after the calcination and still with improvement of insulating properties by using an insulating paste composition containing Al2O3, SiO2 and Bi2O3 in specific proportions. CONSTITUTION:An insulating paste composition contains 40-95mol% Al2O3, 3-50mol% SiO2 and 2-20mol% Bi2O3. A ceramic compact is coated with such insulating paste composition before it is subject to primary calcination. Since the insulating paste is diffused in a substrate before grain growth is started in the material, it is possible to suppress the grain growth in the compact coated with the paste and to prevent expansion of a region having a low dielectric constant after the calcination. Thus, the area of the part having high dielectric constant can be kept and the ceramic compact can be utilized efficiently.
