Abstract: PROBLEM TO BE SOLVED: To adjust the flowrate of gas for controlling pressure in a vacuum container at a low level. SOLUTION: In a process where a substrate 1 is arranged between a cathode electrode 13 and an anode electrode 17 in a vacuum container 11 of a plasma CVD device 10, various kinds of gases are introduced from a gas supply source into the vacuum container 11 via a gas flowrate control device 23, a high-frequency voltage is applied between both electrodes from a high-frequency power supply 22 for generating a plasma, and a CVD film is deposited on the substrate 1, the detection voltage of a pressure detector 19 is compared with a setting one, and the gas flowrate control device 23 is controlled so that M/2 is subtracted from a total flowrate value M when the detected pressure is larger than the one, and the M/2 is added to the total flowrate value M of the gas when the detected pressure is smaller than the set one,  thus controlling the total flowrate of the gas to the vacuum container according to the comparison result between the detected pressure and set one, and hence controlling the pressure inside the vacuum container at a low level even when a variable conductance valve is omitted.

Title: Electric connector
Inventor: BIRII ERITSUKU ORUSON
IPC: H01R12/67
Filed: 1989-11-17
Abstract: PURPOSE: To easily hold a terminal in a connector and easily electrically engage one connector with another by providing the terminal which extends one contact leg out of each joint and keeps spacing to the side wall of a terminal storage hole. CONSTITUTION: A first portion at the axial inner end of a terminal 20 cooperates with the shoulder 70 of a corresponding connector housing 52. When the terminal is inserted into the hollow portion of the housing 52, the first portion the inner end is engaged with the shoulder to operate as a stopper means. In this way, all terminals can be correctly inserted into the housing 52. The terminals 20 correctly positioned are prevented from shift by the inside cooperation with the shoulder. A contact leg 6 is extended out of the second part at the axial inner end. Only one leg 6 is extended out of each axial portion and provided with an engagement portion 76 near the end. The engagement portion cooperates with the pin 80 of another connector for electric engagement between both of them.  As the leg 6 keeps spacing to the side wall of the opening hole 58 of the housing 52, the pin, if somewhat in disorder of array, is acceptable.

Title: Microwave heating device
Inventor: NODA TAKAMITSU
IPC: F24C7/02
Filed: 1987-11-27
Abstract: PURPOSE:To automatically perform zero-adjustment of a weight sensor by supporting a rotating shaft which has a turn table fixedly attached to its top end in such a manner that it is rotatable and axially movable up-and-down, and disposing a weight sensor in a position where the rotating shaft is detachably mounted. CONSTITUTION:A gear 12 is rotated reversely by a control device 19 to cause a meshing projection 11 to abut against an engagement slope 9 of an engagement recess 10 to lift a clutch. Because of the action, a rotating shaft 1 is separated from a weight sensor 6. At this time, a signal value W0 is converted to a digital value by an A/D converter 18 for storing in a microcomputer 19. Then, the gear 12 is again reversed by the control device 19 to cause the meshing projection 11 of the engagement recess 10 to move on an engagement slope 9 to move the clutch 7 downwardly. Because of this movement, the rotating shaft 1 is mounted on the weight sensor 6. A detection signal W from the weight sensor 6 is stored in the microcomputer 19. The microcomputer 19 then computes W-W0-Wt to determine the true weight Wt of foodstuff 4 based on the detected signals W0, W and the previously-stored gross weight Wt of the turn table 5, rotating shaft 1 and clutch 7.

Title: Speed shift operator for transmission
Inventor: MORI OSAMU
IPC: F16H59/02
Filed: 1988-11-28
Abstract: PURPOSE:To improve the quality of a speed shift operation, by making a constitution so that a lock pin may be put into/out of guide grooves at a shifter rod in linkage with a clutch operation, and forming a chamber at the tip portion of the lock pin and inclination surfaces at guide grooves. CONSTITUTION:When a clutch pedal 14 is stepped on and a clutch 6 is cut off, a lock pin 16 is lifted up from a guide groove 51 at a shifter rod 41 through a link mechanism 18, an arm 17, and the turning and movement of the shifter rod 41 become free. After a shifter arm 42 has been engaged with a predetermined shifter rail by means of a shift lever 40, the shifter rod 41 is made to move and then, shifting to a predetermined speed shift step is made. After the completion of a shift operation, the lock pin 16 is pushed down by the release of the stepping on of the clutch pedal 14, and insertion into a guide groove 52 or 53 is made. Accordingly, a premature shift operation before the cutting off of the clutch 6 does not occur. The operational force of the shift lever 40 is lightened due to a chamfer at the tip of the lock pin and the inclination surfaces 52a, 53a of grooves 52, 53.
