IPC: B65H7/02
Filed: 1980-10-09
Abstract: PURPOSE: To promote the running capacity of medium by bringing a detection lever in contact with the medium only for detecting the remaining of the medium.  
     CONSTITUTION: A detection lever 9 composed of a main body 10, projections 11, and supporting parts 12 and 12' is pivotted by pins 13 and 13' on levers 14 and 14' pivotted by shafts 15 and 15', and the lever 14 is constructed to be turned by a magnet 16 via an operation rod 17. When medium 4 runs in a medium running part 1 shaped by guides 5 and 6, the operation rod 17 is drawn back to raise the detection lever 9 by levers 14 and 14', and projections 11 are released from holes 7 and 8 to be positioned on the guide 5. For detecting remained medium, the operation lever 17 is thrusted out to push down the detection lever 9, and projections 11 are made to detect the medium for operating a detection element 18 by the lever 14' when no medium is detected. This construction permits to attain the expected purpose as the detection lever 9 is perfectly prevented from being in contact with the medium 4 during the running of the medium.

Title: Slide surface constituting body
Inventor: GUNJI TAKAHIRO
IPC: C23C30/00
Filed: 1994-05-31
Abstract: PURPOSE:To improve slide characteristics by specifying the area rate and a hydrogen content amount of the square conical metallic crystal of a slide surface. CONSTITUTION:A slide surface constituting body 4 being a metallic crystal aggregate having body-centered cubic structure has a slide surface 4a, which has the area rates A of hexagonal and triangular conical metallic crystals 6 and 7 being set to A >=40%. Thus, the adjoining substances of, for example, the hexagonal metallic crystal 6 are brought into a state to cut through each other, and the slide surface 4a has a number of very fine root parts 8 forming an oil reservoir. Meanwhile, an H (hydrogen) content amount of the metallic crystal aggregate is set to H>=0.01wt.%. This constitution improves hardness of the hexagonal conical metallic crystal 6 and makes it possible that a part of H is present in a crystal. During slide, the tip side of the hexagonal conical metallic crystal 6 is prevented from plastic deformation and sheared and worn in a direction crossing the direction of height owing to brittleness occasioned by inclusion of H. As a result, oil holding ability by the root part 8 is ensured and since face-to-face slide occurs, a friction factor is reduced.

Title: Paper terminal detection in terminal device
Inventor: YOSHIDA KAZUHIRO
IPC: G06K15/16
Filed: 1988-06-09
Abstract: PURPOSE:To facilitate the control for the replacement of output paper by comparing the numerical value of a register for holding number-of-output data having to emit near-end information with that of a counter for counting the push-down number of times of an output demand key to transmit near-end information to a center apparatus on the basis of the coincidence output of both of them. CONSTITUTION:The total length of a volume of hard copy paper and the length of paper used at a time are preliminarily measured and the data of a chance having to emit near-end information is together inputted from a keyboard and a setting means 11 sets said data. An operation means 12 calculates the output number of times having to emit near-end information on the basis of the set data to allow a register 113 to hold this value. When a terminal device is used and a user pushes down the output demand key on the keyboard in order to require hard copy, a counter 114 counts up the push-down number of times of the key. A comparing means 115 alway compares the value of the counter 114 with the value of the register 113 and outputs a coincidence signal when both of them coincide with each other. The coincidence signal is inputted to an information means 116 and near-end information is transmitted to a center apparatus 2 automatically.

Title: Flowmeter
Inventor: MIZUGUCHI KOUJI
IPC: G01F1/708
Filed: 1978-11-20
Abstract: PURPOSE: To make unnecessary the calibration of actual flow, by reducing the drift, through the production of vacuum gap in the flow pass by using the ultrasonic waves and through the direct measurement of flow speed of fluid by the detection of passage of vacuum air voids.  
     CONSTITUTION: The ultrasonic wave oscillator 12 is provided in the pipe 11, and the first and second electrodes 13, 14 are placed with a given distance toward the flow direction at the pipe 11 of the down stream. With this constitution, if the electric good conductor such as sodium flows toward the arrow in the pipe 11, when ultrasonic waves are produced from the ultrasonic wave oscillator 12, local vacuum voids are produced in the fluid. This vacuum void moves in response to the flow of fluid and the passage is detected at the electrodes 13 and 14. Further, the flow can be measured by the time difference passing through the electrodes 13 and 14 and the distance between the electrodes. Thus, the flow speed is directly measured and correct flow measurement can always be made.

Title: Gas laser device
Inventor: KUZUMOTO MASAKI
IPC: H01S3/038
Filed: 1989-06-06
Abstract: PURPOSE:To perform stabilized electric discharge between electrodes by reducing the thickness of dielectric which covers discharge electrodes on opposite sides as it approaches the center, but increasing the thickness as it approaches the ends. CONSTITUTION:When an attempt is made to apply voltage to an electrode 21 in a power supply 7 so that a space electric field reaches a breakdown valve of laser gas, electric discharge is produced in a space. The surface of a discharge section 22a of a dielectric 22 on the power supply side is designed to be curved. The thickness of the dielectric 22 is reduced as it approaches its center while the thickness is increased as it approaches its ends so that it may come into close contact with the convex surface of the electrode 21 on the discharge side. Therefore, the electric field is weaker as it covers the ends of he metal and electrode 21, which minimizes the effect of edge of the electrode 21 and makes constant the distribution of power density so that homogeneous discharge power distribution may be obtained between the discharge sections 22a of the dielectric 22. Therefore, it is possible to obtain stabilized discharge at high power density. At the same time, a total thickness B of a non-discharge section 22b of the dielectric 22 is formed to be greater than the thickness of the discharge section 22a in the central part, which reduces the capacitance of the non-discharge section 22b. On the other hand, as for the discharge region, the discharge power density is not reduced between the discharge sections 22a and 22b, which makes it possible to prevent the drop in the efficiency of laser oscillation.

IPC: F25B49/02
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To enable screw connection and reduce a mounting space by disposing a fusible plug in which a low melting point material is filled between a refrigerant sealing hole communicated with a cooling cycle at all times and an external part. SOLUTION: There is formed a vent hole 21 between an atmosphere side, i.e., an external part and a refrigerant sealing hole 13 communicated with the inside of a cooling cycle when a charge valve 10 is mounted on the cooling cycle. A low melting point solder 22 is filled in the vent hole 21 which is melted at a relatively low temperature. Further, a screw part is formed in an internal surface of the vent hole 21, and a contact part with the low melting point solder 22 is made uneven whereby a sealing property upon normal operation is ensured and a heat reception surface is ensured. When a refrigerant is sealed in the cooling cycle, a screw part 17 is connected with a refrigerant supply nozzle, and a pin 14a is pushed with screwing of the screw to open an opening/closing valve of a valve core 14 for supply of the refrigerant.  When any abnormality is produced in the cooling cycle and temperature and pressure become abnormal, the low melting point solder 22 is melted with heat thereof, and hence the vent hole 21 is communicated with the outside to release the refrigerant with the pressure.
