Abstract: PROBLEM TO BE SOLVED: To deeply form a scribing line without the occurrence of chipping, etc., and to smoothly guide a cutter to a work with a scribing device for forming the scribing line on the work surface prior to work breakage. SOLUTION: The cutter 30 is mounted at the bottom end of a holder 20.

A guide member 35 is mounted at the holder 20. The guide member 35 has a bridge part 35b floating from the holder 20 and is formed nearly to a U shape. The right and left half parts each of the bridge part 35b are provided as the guide parts. The guide parts incline with the relative moving direction of the cutter 30 and guide the cutter 30 at the time of feeding the cutter 30 to the work.

Title: Air valve
Inventor: KITAMURA MASAAKI
IPC: F16K24/04
Filed: 1989-04-21
Abstract: PURPOSE:To prevent an exhaust port from being closed by a floating valve during the period of time for exhausting a plenty of air by providing a plurality of air vent holes for the circumference of the inlet port of a float ih the air valve equipped with the floating valve which opens/closes the air vent holes by vertically moving the float. CONSTITUTION:A plurality of air vent holes 14 is provided for the circumferential section of the air inlet port 13 of a float 2. When fluid in a pipe line does not flow in a valve box 1, an exhaust port 10 is opened by a float valve 3 with the float 2 moved down so that a plenty of air in the pipe line is exhansted out to atmosphere. When fluid in the pipe line flows in the valve box 1, the float valve 3 is pressed onto the exhaust port 10 with the float 2 raised up, the overflow of fluid to atmosphere is thereby prevented. when a plenty of air is exhausted with the float 2 lowered, air sometime flows into a gap between the lower surface of the float 2 and the bottom section of a lower valve box 7, an air vent hole 14 however sets said air free above the float 2. By this constitution, the floating valve 3 thereby will never close the exhaust port 10 while the float 2 is raised upward by air pressure.

Title: Driving device of fuel injection valve
Inventor: KATSU MASAHIKO
IPC: F02D45/00
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To suppress dispersion of a fuel injection characteristic due to a change of the characteristic of a piezoelectric element and a dimensional tolerance by learning and correcting a closing valve signal or an opening valve signal so that a difference of load fluctuation amount which is a difference of load at the valve closing time and load at the valve-opening time and a preliminarily set load fluctuation set value may be eliminated. SOLUTION: In a controller 5, a load measuring part 51 calculates a learning correction value ΔVo1d and a correction value Va of driving voltage V, based on detection voltage V 2s according to load Fvs at the valve-closing detected by time a load sensor 7 and detection voltage V 2i according to load Fvo at the valve-opening time. A driving part 52 performs an opening and closing driving of an actuator 10 by a driving voltage difference ΔV (Vs-Vi) based on these learning and correction valves. In this case, Vs and Vi are preliminarily set closing valve voltage and opening valve voltage, respectively. The correction valve Va is calculated from a difference of load fluctuation amount ΔF (Fvs-Fvo) and a preliminary set load fluctuation amount set value ΔF0.  Fluctuation of a fuel injection characteristic due to secular changes can be suppressed and the secular changes of a dimensional tolerance can be absorbed.

Filed: 1988-04-27
Abstract: PURPOSE:To change a substrate conveyance speed without causing changes in the thickness and optical properties of a film and also deterioration in productivity by regulating the erosion area of a target under specific conditions without changing the sputter power density of a target. CONSTITUTION:In a sputtering device of a substrate passing system, film formation is carried out while changing the substrate conveyance speed.

Filed: 1987-04-24
Abstract: PURPOSE:To prevent the consumption of a battery by using a motor for switching filter which selects focus detecting light beam and motor for winding and rewinding a film in combination and preferring the actions of winding and rewinding the film. CONSTITUTION:A control circuit 208 makes the motor 203 rotate in a first direction according to the command of a first command means 205. And a filter driving means 204 makes either of two filter elements 202 advanced ahead of a focus detecting element 201. Meanwhile, the circuit 208 makes the motor 203 rotate in a second direction according to th4e command from a second command means 207. Thus, a film driving means 206 winds or rewinds the film 209. When the command is issued from the means 207 while the means 204 is actuating, the circuit 208 makes the motor 203 rotate in the second direction so as to preferentially execute the winding or the rewinding. Thus, convinience in a main reflection mirror for single-lens can be improved and the consumption of the battery can be prevented.

Title: Sweeping circuit for oscilloscope
Inventor: ICHIJO HIROSHI
IPC: G01R13/24
Filed: 1986-05-07
Abstract: PURPOSE:To obtain a sweeping speed at any time, by running an output current of a control current source to a capacitor composing a sweeping circuit to charge so that the output current value thereof is made programmable while the output current value is measured. CONSTITUTION:When an increment/decrement counter 14 is set to a maximum possible set value under the calibration of the sweeping speed, the maximum of a current (i) and a current i2 flows through a D/A converter 16 as reference current. Under such a condition, when the set data of the sweeping speed is altered, an output current i1 of the converter 16 varies with the alteration thereof. As this current i1 charges a capacitor 2, the gradient of a saw tooth wave of a sweeping output is changed to accomplish a switching of the sweeping speed. Then, when a clock pulse is applied to the counter 14, the output current i2 of a converter 15 changes corresponding to a count value of the counter 14. Now when the maximum of the current i2 is set smaller than the current (i), the counter 14 is decremented to make the sweeping speed variable within the speed corresponding to a set sweeping speed data for the converter 16. Thus, the measuring of the altered value of the sweeping speed can be done with the counter 14.
