Title: Job flow generation system
Inventor: KURATA YOJI
IPC: G06F9/06
Filed: 1990-09-06
Abstract: PURPOSE:To make a work time efficient, to average the quality of a job flow and to generate the job flow which is easy to be viewed by automatizing a job flow generation job. CONSTITUTION:A step pattern generation bit 7 generates the job flow of respective units based on information obtained in a step decoding part 5 and an input/ output device recognition part 6.

Title: Positive display device of liquid crystal light bulb
Inventor: KUBOTA KEIICHI
IPC: G02F1/133
Filed: 1983-12-15
Abstract: PURPOSE:To speed up a repeating display time by heating a liquid crystal light bulb by flash lamps to make the light bulb dispersed status, forming a transparent pattern on the light bulb by laser light and projecting the pattern by a projecting light source. CONSTITUTION:A liquid crystal light bulb 10 is irradiated by flash lamps 24, 25 and entirely dispersed to make the liquid crystal opaque.

Title: Semi-automatic chuck of pipe or the like
Inventor: IGAMI SHIGEOMI
IPC: B23B31/12
Filed: 1986-10-03
Abstract: PURPOSE:To make it possible to automatically chuck a pipe or the like and manually release it by forming the chuck edge of a chuck bar corresponding to the outer periphery of the pipe or the like into a circular arc increasing in order the degree of the projection thereof in the driving direction of a drive disk. CONSTITUTION:When a motor is started for driving a drive disk 3 in the direction of the X-axis with a pipe or the like P made to penetrate into through holes 5 and 6, since a chuck body 1 is in a stopped state, the shaft 10 of the end of the lever 8 rotating along with the drive disk 3 is separated from the centers of the through holes 5 and 6 in the guide hole 7 of the chuck body 1. Since, at the same time, a shaft 9 is rotated counterclockwise for interlocking a chuck bar 15, a chuck edge 20 projects from the hole edge 5a of the through hole 5 toward the center for generating the chucking force cutting into the outer periphery of the pipe P. And the body 1 is connected to the disk 3 and is moved along with the disk 3 at the same speed of the shaft in the direction of the X-axis, and the pipe P chucked by the chuck edge 20 also rotates in the same direction. Since the shaft 10 is forced to move in the direction of the X-axis in the hole 7 also in this rotation resulting in the counterclockwise rotation of the shaft 9, the chuck bar 15 also makes the edge 20 cut into the outer periphery of the pipe more and more.

Title: Surface-grinding machine in semiconductor production system
Inventor: MATSUSAKO YUJI
IPC: B24B37/04
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a surface-grinding machine in a semiconductor production system in which cost can be reduced by shortening the working time, while effectively projecting the lower surface of a semiconductor wafer SOLUTION: A table 10 is provided with air ejection holes 18a, 18b, and the upper surface of a wafer 1 is ground by means of a grinding blade 13 with the lower surface of the wafer 1 which is supported by the pressure of ejected air. When the air pressure is imparted with a gradient, the wafer 1 can be floated obliquely. The wafer 1 is abutted, at one end part (orientation flatness) thereof, against a stopper 11 and is secured in place. Since grinding work can be conducted without bringing the lower surface of the wafer 1 into contact with the table 10, the lower surface of the wafer 1 requires no surface protection, resulting in shortening of working time and cost reduction.

Title: Catalytic combustion equipment
Inventor: IWAI KAZUMI
IPC: F23R3/40
Filed: 1985-10-25
Abstract: PURPOSE:To obtain a combustion gas having NOx content nearly as low as that attained by a catalytic combustion, by mixing fuels required for a heat retainer located downstream a catalyst layer into combustion gas produced by a catalytic reaction at a preceding stage, and providing a means for controlling a flow rate of air mixed thereinto. CONSTITUTION:Premixing gases 3 are mixed and preheated in a premixing chamber 17 and led to a first stage of catalyst 7. As the catalyst 7 is preheated to above a temperature of activation, the premixing gas guided in react there and flow into a combustion chamber 18 in the forms of combustion gas. The temperature of combustion gas at that time is approximately equal to a temperature of heat resistance of the catalyst. A heat retainer 8 receives heat from the combustion gas generated by the first stage of catalyst when fuel is not supplied to the upstream side of said heat retainer and becomes a high-temperature member. To obtain a temperature of gas higher than a combustion gas obtainable by a catalytic combustion reaction at the first stage, fuels having such quantity that corresponds to a required temperature rise are supplied into the combustion gas through a fuel supply passage 10. In this case, amount of combustion air is made less than the theoretical amount of air required for the flow rate of supplied fuel or none of said air is supplied.

Title: Controller for brushless motor
Inventor: SUNAGA HIDEKI
IPC: H02P6/08
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain a controller for brushless motors which is capable of controlling rotational speed over a wide range of speed with accuracy. SOLUTION: Data table 11b is created in advance in which data table data An and Bn for reducing differences between actual rotational speeds and target values due to causes which steadily occur during running of a brushless motor is stored in relation to each unit speed range of unit speed range groups obtained by dividing the rotational speed range into a plurality of segments. When a target value Din for rotational speed is input, a data sampling means 11a samples data An and Bn from the data table 11b according to the input value. Drive controlling means (11c, 11d, 12e) corrects the target value Din using the sampled data An and Bn, and further controls driving of the brushless motor based on the corrected target value Dout. Therefore, the rotational speed of the brushless motor is controlled over a wide range from low speed to high speed with accuracy.

Filed: 1986-10-06
Abstract: PURPOSE:To perform focus detection regardless of power variation by comparing contrast values at two lengthwise positions of a line sensor with each other while holding an image forming lens inclined, and calculating a focus error. CONSTITUTION:While the image forming lens 8 slants to an optical axis 34, the combination of peak values of contrast waveforms outputted at >=2 lengthwise positions of the sensor 4 is different according to an in-focus, a front-focus, and a rear-focus state.

A driving circuit 40 is controlled according to the detection signal to stop a driving motor 39 for focus adjustment in the in focus state, rotate the motor 39 forward in the front-focus state so as to move an image forming lens 8 toward the sensor 4, or reverse the motor 39 in the rear-focus state to move the lens 8 away from the sensor 4. Consequently, the lens 4 is slanted temporarily by a solenoid 37 to make an automatic focus adjustment.
