Title: Gas laser oscillator
Inventor: KUROIWA AKIRA
IPC: H01S3/03
Filed: 1978-07-17
Abstract: PURPOSE:To improve efficiency in assembling work, by inserting into the gap between laser tube and cylindrical case a spring component of the structure such that a group of cut pieces of spring plate bent nearly 180 deg. is formed into a ring shape. CONSTITUTION:Spring material, such as phosphorus-bronze, is punched into finger- shaped pieces by press processing. They are bent nearly 180 deg. and a group of these pieces is formed into a ring shape, and thereby spring component 3 is constructed. This component is inserted into the gap between the inner surface of cylindrical case 1, made of aluminum pipe, and the outer surface of laser tube 2. By this, a force to expand inside the gap comes into play, and it is possible to integrate completely case 1 and laser tube 2. Thus, work efficiency is greatly improved by inserting this component only.

Title: Oil content measuring instrument for refrigerating cycle
Inventor: YOSHIMURA HIROSHI
IPC: F25B49/02
Filed: 1988-04-08
Abstract: PURPOSE:To easily measure the content of oil in a refrigerant by interposing a sampling container in a line which makes a bypass connection between a condenser downstream side and a compressor low-pressure side. CONSTITUTION:When the oil content is measured, an opening/closing valve 22a is opened in stationary operation to put a liquid refrigerant in the sampling container 20 by a prescribed amount, and its volume is read. Then when an opening/closing valve 22 is opened, the liquid refrigerant in the sampling container 20 boils and vaporizes at a constant speed with the suctional force of the low pressure side of a compressor 12, so that only the gaseous refrigerant is sucked to the compressor 12 through a constant-flow-rate valve 23. When the temperature of the liquid refrigerant in the sampling container 20 drops, a temperature sensor 28 detects that and turns on a temperature controller 27 to accelerate the vaporization of the liquid refrigerant. When the vaporization is finished, the opening/closing valve 22b is closed, the level of the oil remaining in the sampling container 20 is read on a scale, and the volumetric circulation rate of the oil to the refrigerant is found from the volume of the oil and the volume of the liquid refrigerant which flows in the container first.

Title: Controller for stepping motor
Inventor: MURAMATSU SHIGEKI
IPC: H02P8/12
Filed: 1990-04-02
Abstract: PURPOSE:To control a motor in a closed loop without using an encoder by comparing the frequency of a drive pulse detected by drive pulse detecting means for detecting the drive pulse to be supplied to a coil of a stepping motor with that of a reference pulse, and correcting the drive pulse in response to the frequency difference. CONSTITUTION:An analog-to-digital converter 6 detects an A-phase voltage at a predetermined threshold level to convert it into a pulse signal, and inputs it to a CPU of a microcomputer 1. The CPU applies a signal corresponding to a stored peak current value of a resistor 8 at the time of a predetermined rotating speed to a reference voltage circuit 2, which converts it to an analog signal, which is input to a comparator 3. The output decides the duty ratio of the drive pulse. A chopper 4 generates a pulse at a predetermined duty ratio in a predetermined frequency, and controls its rotating speed through a transistor 7. On the other hand, the output of a pulse generator 5 is applied to the base of a motor control transistor to control a rotating phase.

IPC: G11B5/127
Filed: 1989-04-08
Abstract: PURPOSE:To shorten the manhour of a manufacture and to execute an inexpensiveness by executing a first cutting work so as to be thicker by a specific thickness than a prescribed thickness, thereafter, executing a second cutting, and finishing a magnetic head core in the prescribed thickness. CONSTITUTION:Magnetic substance blocks 2 and 3 having a groove 1 for a coil winding made of a ferrite are integrated in forming a magnetic gap 5 by using a bonding glass 4. A cutting 7 is executed so that a magnetic head core block 6 obtained in such a way can remain thicker by several microns to scores of microns than the prescribed thickness. At such a time, a magnetic head core 8 after the cutting is bondingly fixed in a bottom part. Next, a cutting 9 is executed by using a grindstone to be thick only at a work allowance, and the magnetic head core 8 in a prescribed size is completed. Thus, since the work is completed on the same jig up to the core 8 completion, the manhour can be reduced, and the inexpensiveness can be executed.

Title: Arc welding method
Inventor: MORIYASU MASAHARU
IPC: B23K9/02
Filed: 1983-05-20
Abstract: PURPOSE:To perform profiling of a weld line with high accuracy by moving rotationally an arc by using a spiral wire, detecting and processing the current change during the rotation, determining the lateral deviation of the arc and controlling the position of a torch until the deviation is made zero. CONSTITUTION:An arc 8 is rotationally moved by using a spiral wire 70 and the signal indicating the change in welding current or voltage is passed through a filter having a cut-off frequency of about the rotating frequency of the arc. Whether the position where said change arises is forward F or backward B in the advancing direction is identified from the comparison of the 1st prescribed values past the filter with each other and whether the position where said change arises is on the left L or right R is likewise identified from the comparison of the 2nd prescribed values with each other, by which the lateral deviation of said signal is detected. The position of a welding torch is thus controlled until said deviation is made zero, by which the follow up of the weld line is accomplished. The automatic follow-up of the weld line with high accuracy with the arc itself as a sensor is thus made possible and there is no directivity in the detection. The above-mentioned method is applicable for a robot.
