Title: Parts setting chuck
Inventor: MIYAZAKI TOMOTOSHI
IPC: B23P19/04
Filed: 1987-11-05
Abstract: PURPOSE:To locate each of parts at a home position all the time by holding and positioning each part in the almost rectangular direction to the moving direction of a push rod with each two-set of holding members doing relatively parallel movements each via each link member. CONSTITUTION:When parts setting chucks 11, 12 fixed to a base 13 are moved onto a parts feeding position, a connecting slider 35 is lowered via a spring 35b with a piston 30 going down, and comes into contact with a topper 55. At this time, a slide base 39 and a guide 40 both also go down via a shaft 38, whereby respective link members 43 are pulled with one another by a spring 53, moving each holding member 42 in the opening direction, whereby these holding members come into a state of making electronic parts 15 holdable. Next, when the piston 30 goes up, the electronic part 15 is held by these four holding members 42, and then it is attracted and held by a suction pin 33a of a push rod 33. Thus, the electronic part is held without any strain and, what is more, an accurate location to the push rod can be done.

Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To suppress generation of manual shifting mode which the driver does not intend with an automatic transmission of such a configuration as including an Auto range to make change-over of a shift position automatically and a manual range to make changing over manually. SOLUTION: In the manual range selecting position, a shift lever is furnished with a shift-up switch 53 and shift-down switch 54 which are turned on when contacting pieces 54a are pressed with a swing of a front and a rear cam 51 and 52.

Title: Starting/stopping control circuit for power source equipment
Inventor: WASHIO TOSHIFUMI
IPC: H02J1/00
Filed: 1990-10-18
Abstract: PURPOSE:To prevent the burning of a connector contact caused by a rush current by making a voltage generation circuit to generate a start signal on the basis of an electric current supplied from a battery through a ground line so as to actuate a power generating section in a power source unit when the power source unit is connected to a back wiring board while the start switch of the unit is turned on. CONSTITUTION:A power source unit is connected to a back wiring board(BWB) 10 through a connector diagram. When the unit is connected to the board 10, an electric current (i) starts to flow from G line to -48V (or 24V) through the BWB 10, R1, Dz1, and R2. Then the potential at a transistor Q1 is turned off and the collector of the transistor Q1 becomes equal to that of the G line, namely, 0V. The potential becomes level '1' and, when the level '1' is used as a power source start signal, various kinds of power supply voltage generating sections are started in the power source unit. Therefore, even when the power source unit is connected to the BWB 10 while a start switch 13 is turned on, no rush current flows and burning of a connector can be prevented.

Title: Controlling mechanism of facing drum
Inventor: YAMASHITA KEIICHI
IPC: B23Q5/40
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To cope with high speed operation by solving such problems as defective positioning accuracy of a tool rest, which is caused by errors due to a backlash of each gear in a conventional differential speed changer, and as noises attributed to the rotation of each gear. SOLUTION: In a controlling mechanism in a facing drum, a facing drum 4 is attached to the tip end of a main spindle 3, a tool rest 6 is engaged with the drum 4 in such a manner that it (6) is able to move on the end surface of the facing drum and in the radial direction via a feed shaft 21, and the feed shaft 21 is inserted into the main spindle 3 in a freely rotatable manner, so that the position of the tool rest 6 can be changed owing to a difference in rotational phase between the main spindle 3 and the feed shaft 21. In this case, when the position of the tool rest 6 is to be fixed, a main spindle motor 1 is driven so that both main spindle 3 and feed shaft 21 rotate at the same speed constantly, while a feed servomotor 30 is stopped. When the tool rest 6 is to be moved, the servomotor 30 is driven regardless of the rotation of the main spindle motor 1 so that the feed shaft 21 is moved by the quantity as required. In other words, the main spindle motor 1 and the servomotor 30 are constituted independently.

IPC: H04J14/00
Filed: 1992-09-08
Abstract: PURPOSE: To dispense with any construction process except for processes required for providing an optical waveguide to be connected by coupling a wavelength selective mode converter and a mode splitter, not dependent on any wavelength. CONSTITUTION: A mode converter 3 utilizes the fact that it is selective, concerning not only a special waveguide mode but also concerning that waveguide mode with the special wavelength of an optical signal. Therefore, this mode converter 3 is selective in the wavelength. On the other hand, a mode splitter 5 utilizes the fact that it does not depend extremely on any wavelength. Then the mode splitter 5 is made into asymmetric junction. Thus, the optical signal of wavelength having fixed polarization and the optical signal of the other wavelength can be separated or coupled.
