Title: Portable cutting device
Inventor: FUKUDA KEN
IPC: B23D45/02
Filed: 1990-11-28
Abstract: PURPOSE:To carry out cutting work without using a grinding stone, to reduce the size of a device, and to improve the workability and the precision in cutting size by providing a block, a screw slotting cutter, a motor, a table, a pressing mechanism, and a moving mechanism. CONSTITUTION:A material O to be cut is inserted into a groove of a table 14 at a desired cutting angle, and the material O to be cut is moved along the groove, while a clamp 18 is rotated and the material O to be cut is fixed to the upper part of a table 14 by a press plate 16. The table 14 is pushed in the direction of a cutting blade 3. The fluctuating of the position set at the time is inhibited since the position regulating is carried out when the table 14 is displaced from a cutting line by a guide shaft 10a and so on. The end of a screw shaft is put on the screw hole of a block 2a at a point just before the position where the material O to be cut is cut by the screw slotting cutter 3. By turning a handle 21, the screw shaft is screwed into the screw hole of the block 2a, and the cutting is carried out according to the rotational speed of the handle 21.

Filed: 1991-11-15
Abstract: PURPOSE: To reduce a stress of a track by allowing a ball to connect to tracks of an electronic circuit having a portion not sticking to the electronic circuit at a location of a connection region and its surroundings. CONSTITUTION: An electronic circuit 1 is disposed on a ball 10 fused and solidified, and the ball 10 is refused without bring close electronic circuits 1, 2 to each other. A connection of the electronic circuits 1, 2 is immediately established by resolidifying the ball 10. Preferably, a connection region 9 is made small to obtain the most spherical possible ball 10. Further, a width of a track 5 is made preferably smaller than a diameter of the ball 10 (e.g. 4-20 micron each).

Title: Transmission torque control device for rotation difference sensing joint
Inventor: KITAMURA KOICHI
IPC: F16D31/00
Filed: 1991-12-12
Abstract: PURPOSE:To ensure high responsiveness of transmission torque from a low relative rotation difference region to a high relative rotation difference region by controlling an orifice opening based on the target orifice opening calculation containing a correction term which is proportional to the derivative of the relative rotation difference, and inversely proportional to a relative rotation difference. CONSTITUTION:A relative rotation difference detecting means (d) detects a relative rotation difference between a housing and a rotor, a relative rotation difference-differential value calculating means (e) calculates the differential value, a target orifice opening calculating means (f) calculates the target opening based on the operational equation containing a correction term which is proportional to the differential value, and inversely proportional to the relative rotation difference, and a transmission torque control means (g) outputs a drive controlling command for obtaining the target opening to an actuator (a). When a variable orifice (b) of a rotation difference sensing joint (c) is set to a specified opening by the controlling operation, the delivery oil to an accumulator chamber is controlled in response to this to generate a joint-transmission torque which corresponds to the relative rotation difference. Thus, the flow rate is increased in a low relative rotation difference area, and an increase in the flow rare in a high relative rotation difference area is restricted by an amount of correction. The same responsiveness can thus be obtained over the whole area.
