Patent JP-S6062683-A (JP)
Title: Gear pump
Inventor: NAGAO TADASHI
IPC: F04C2/18
Filed: 1984-03-05
Abstract: PURPOSE:To rotate a gear smoothly without sacrifice of pump efficiency, by projecting a shaft for supporting the gear from the bottom wall of gear chamber while forming a ceiling wall at the position slightly lowered to the inside at the opposite side from the gear shaft inserting side. CONSTITUTION:A shaft 13 for supporting a gear 5 is projected from the bottom wall 8 of gear chamber 6 while ceiling wall 5a is formed at the position slightly lowered to the inside at the opposite side from the gear inserting side, where the length of the shaft 13 is set not to contact with the ceiling wall 5a. Consequently, even when the body case 1 and the gear 5 are made of highly shrinkable synthetic resin, the supporting structure of gear 5 is simplified through cantilever to enable simplification of assembling. While since fastening deformation force due to the liquid pressure to be produced under usage can be compensated by the ceiling wall 5a, the gears 4, 5 can be rotated smoothly without sacrifice of pump efficiency.

Abstract: PURPOSE:To provide an ultrasonic dimensional monitor which is able to improve the operation efficiency and machine a workpiece so well into a desired finishing size. CONSTITUTION:Ultrasonic waves out of an ultrasonic probe 1 installed in a cutting oil feeding nozzle 2 are propagated to a round bar 4 in making cutting oil flowing out of the nozzle 2 as a medium, and it is reflected at a surface 4a and a bottom surface of the round bar 4, while it is amplified by a pulser- receiver amplifier 7 as each of second and third reflected waves and inputted into a signal processor 8 which detects each input time of these inputted second and third reflected waves and measures a time difference T between respective peak values of both of them, thereby calculating a diametral size of the round bar 4.

Title: Production of thin film magnetic head
Inventor: IWANO YASUHIRO
IPC: G11B5/31
Filed: 1994-03-14
Abstract: PURPOSE:To improve the mass-productivity by forming a metal thin film on a magnetic film in such a manner that the etching rate of the metal thin film for an etching liquid is enough smaller than that of the magnetic film and chemically etching the magnetic film with this metal thin film as a mask. CONSTITUTION:When a pattern of the magnetic film 12 is formed, a metal thin film 13 is formed between the magnetic film 12 and a photoresist 14 in such a manner that the etching rate of the film 13 for an etching liquid is enough smaller than that of the magnetic film 12, and the film 13 is used as a metal mask. By this constitution, adhesion strength of the photoresist to the magnetic film 12 which is weak when only the photoresist is used is improved. Therefore, the amt. of side etching during etching can be decreased. Thus, a production method of a thin film magnetic head excellent in accuracy of the track width and massproductivity is realized.

Abstract: PURPOSE:To shorten the operating cycle of an ultrasonic sensor as well as to make the positional detection of an obstacle to be conducted accurately, by operating plural ultrasonic sensors simultaneously with every interval proportionate to a measurable distance of each ultrasonic sensor. CONSTITUTION:In the case where this system is put into operation to detect an obstacle in the way of the left side of a large-sized vehicle 1, ultrasonic sensors 2 are set up at regular intervals on the left side of the large-sized vehicle 1, controlling each of them by a processing unit 3, and the detected obstacle is displayed by a display unit 4.

Likewise, a rotor forms a metal film 202 thereon after having been roughly processed and then is processed for finishing. A device employing this ceramic material is not subjected to an obstable in the operation by an effect caused by the change of an environmental temperature.

Abstract: PURPOSE:To automatically detect the position of the line of sight only when the position of the line of sight is required to be detected and also to improve the responsiveness of a line of sight position detector by providing a means deciding the start of the detection of the line of sight. CONSTITUTION:A CPU 218 judges whether the detection of the line of sight is started or not based on a specified decision condition. The specified decision condition is, for example, whether the eye of a photographer is brought into contact with a finder 203 or not. When the eye of the photographer is brought into contact with the finder 203, the CPU 218 resets the timer of a power source, and the timer starts counting. And the position of the line of sight of the photographer is detected by a circuit 210 detecting the position of the line of sight. When the half-pressing switch SW1 of a releasing button is pressed, the CPU 218 fixes a focal point detecting area and a photometric area to the position of the line of sight detected by the circuit 210. The position of the line of sight of the circuit 210 is not locked at this time, and the working of the circuit 210 is not stopped.

IPC: F23N1/00
Filed: 1983-03-15
Abstract: PURPOSE:To provide an adequate closure capability and to stabilize the pressure control characteristics by disposing a magnetic plunger having a permanent magnet inside a solenoid valve and bringing the magnetic plunger in contact with a valve body through a slide pin. CONSTITUTION:A magnetic plunger 24 having a permanent magnet 23 in it is inserted into a solenoid 20. The magnetic plunger 24 is supported by two leaf springs 33. The magnetic plunger 24 is brought in contact with a vlave body 16 through a slide pin 29, and the valve body 16 is biased toward the first vlave seat 14 by magnetism of the permanent magnet 23.

Title: Method and apparatus for measuring evaporated quantity of low-temperature liquified gas
Inventor: FURUTO YOSHIO
IPC: G01F17/00
Filed: 1990-02-27
Abstract: PURPOSE:To measure the quantity of evaporation highly accurately in a short time maintaining pressure at the downstream side of a flowmeter for measuring the evaporated quantity of low-temperature liquified gas at a constant pressure which is higher than the fluctuating range of atmospheric pressure. CONSTITUTION:A gas container 7 and a control valve 8 are connected at the downstream side of a flowmeter 6. Helium vapor which is passed through the flowmeter 6 once enters into the gas container 7. Thereafter, the vapor is discharged into the atmosphere through the control valve 8. A pressure sensor 9 is attached in the container 7. The detected value is inputted into a control unit 10. The pressure in the unit is set at a value which is higher than the upper limit of the fluctuating range of the atmospheric pressure, e.g. by about 10 - 20mmHg. In the unit 10, the preset value and the detected value are compared, and the difference is outputted. The opening degree of the control valve 8 is adjusted with the output. Thus, the pressure in the container 7 is kept at the preset value. As a result, the pressure in the container 7 is maintained at the constant pressure that is higher than the fluctuating range of the atmospheric pressure. Therefore, the flowmeter 7 can measure the flow rate without the effect of the fluctuation of the atmospheric pressure.
