Title: Exhaust gas recirculation device of engine
Inventor: HAYAMA NOBUHIRO
IPC: F02B29/02
Filed: 1982-02-03
Abstract: PURPOSE:To suppress an increase of engine speed and prevent occurrence of an overrunning condition, by increasing an amount of exhaust gas recirculation (EGR) when an actual engine speed is larger than the engine speed correspondingly set to an accelerator operated amount. CONSTITUTION:An accelerator operated amount signal detected by an accelerator sensor 10 is received to calculate open and close timing of an intake valve 7 in accordance with an operational condition, and a timing cam 8 is operated to open and close the valve 7 with prescribed timing and control an intake recirculation amount. At a maximum accelerator operated amount, the valve 7 is early closed as shown by a curve A in the drawing to decrease the recirculation amount and increase a charge amount, while at a minimum accelerator operated amount, the valve 7 is late closed as shown by a curve B in the drawing to increase the recirculation amount and decrease the charge amount.

Title: Encapsulation molding tool
Inventor: HATTORI KAZUO
IPC: B29C45/14
Filed: 1987-01-27
Abstract: PURPOSE:To facilitate encapsulation-mold with no generation of flash even when the thickness of an insert fluctuates by a method wherein each floating force provided on a bottom force is resiliently energized toward a top force side. CONSTITUTION:A bottom force 2 consists of a bottom force molding part 8 and a keep plate 9. Floating forces 4, 4... are mounted to respective openings 10, 10..., which are provided on the bottom force molding part 8. Each substrate 15 is insertedly set in each cavity 3 of the bottom force so as to be pinched by abutting the underside of the substrate 15 against the top surface of the floating force 4, and the top surface of the substrate 15 against the underside of the top force 1, and encapsulating resin is poured in the recess 16 of the substrate 15. In this case, if the substrate 15 is thinner, the floating force 4 is pushed up by the resilient force of a spring 5, while if the substrate 15 is thick, the floating force 4 is pushed down, resulting in allowing to prevent the resin, which fills the recess 16, from producing flash at the top surface of the substrate 15 through a gap generated between the top surface of the substrate 15 and the top force 1.

Filed: 1978-02-20
Abstract: PURPOSE: To form the 3-color fluorescent film by the dam-print system by using the dam-shaped  glass funnel with the fluorescent substance pattern formation area processed into the groove.   
     CONSTITUTION: Resist pattern 2' is formed on glass panel 1; dam shape 3' of about 20μm deep  is etched via the solution containing HF as the main component; and the resit is removed after  washing by the water. The convexpart of the dam features about 60μm width, about 80μn bottom width and 74mm length, and 720 pieces of such dams are arranged in the x direction with  140μm pitch. And the area of the pattern measures 100× 74mm. Then the paste mixed with the  graphite powder is coated only to the convex part of the dam to form black matrix pattern 4.  Then the RGB color fluorescent substance paste of about 1000 poise is filled by printing and with  positioning to each dam 3'. Owing to the controlling effect of the dam, the printing is given at the  fixed area with no color mixture caused even if the positioning may be shifted by about 30μm.  After this, the filming, the Al deposition and the burning are carried out in sequence. With this  method, a high-accuracy is ensured for each color with no mixture to each other, the pattern  accuracy is within 10μm, and both the luminance and the picture quality are excellent.

Filed: 1984-02-01
Abstract: PURPOSE:To make raster displace in the upper/lower of vertical directions without increasing DC by supplying DC to a load circuit through a vertical deflection coil and current limit resistance and by deciding a raster position. CONSTITUTION:A current limit resistance 10 is connected in parallel with a coil 9 and a connection point P1. of the resistance 10 and capacitor 8 are connected through a resistance 4 to an output of a DC power source device 2. A power source terminal of a small signal circuit 3 is connected to the coil 9 and a connection point P2 of a capacitor 5. Where the DC superimposed on the coil 9 is 40mA so as to displace the raster, for example, in the upper direction, 10mA is shunted by the resistance 10 so as to flow 50mA in the circuit. In this way, the device effectively uses the current flowing in other circuits, thereby enabling displacement of the raster without any current increase of the device.

Abstract: PURPOSE:To provide the oxide piezoelectric material having low dielectric constant and ready sintering with large coupling coefficient ratio by setting x=0.01-0.10, a=0.05-0.35 in (Pb1/2Caa)[(Me1/3Nb2/3)xTi1-x]O3 basic composition. CONSTITUTION:In the basic composition of (Pb1-aCaa)[(Me1/3Nb2/3)xTi1-x]O3, where Me signifies any of Mg and Zn, the value of the coupling coefficient Kp in the expanding direction becomes higher than 5% even if a<0.05 or a>0.35, and spurious is frequently generated. If a>0.35, the dielectric constant becomes higher  than 300, which is disadvantageous in the application of the high frequency. If  x<0.01, the effect of Pb(Me1/3Nb2/3)O3 for decreasing the sintering temperature of the porcelain is not presented. If x>0.10, the Kp is increased. 0.05-2.0wt%, of any of Mno, NiO and Fe2O3 is added to improve the sintering and polarizing properties of the porcelain.

Title: Method of tapping
Inventor: KITANI NOBUYUKI
IPC: G05B19/18
Filed: 1984-02-03
Abstract: PURPOSE:To enable high-accuracy tapping, by using a tapping tool rigid enough not to expand and contract, to solve a problem arising from inertial rotation. CONSTITUTION:For threading, a spindle or a tapping tool 4 is quickly moved to an initial point Pi, simultaneously along two axes X, Y while the tool is rotated at a constant speed. After the tool 4 is moved to an aimed position Pe, a spindle reversing instruction is applied to rotate the spindle backward. While the spindle is rotating forward due to inertia, the tool 4 is moved to a point Pm in the direction of depth synchronously with the rotation of the spindle, by distributed pulses. After the rotation of the spindle is reversed at the point Pm, the tool 4 is moved up to a point Pr by distributed pulses. After the tool 4 is moved to the point Pr, a pulse distribution operation based on the pitch of the thread is terminated. According to this method, a problem arising from inertial rotation is solved to enable high-accuracy tapping.
