Patent JP-H04132883-A (JP)
Title: Air-driven pump
Inventor: KONDO SHIGEO
IPC: F04B9/135
Filed: 1990-09-21
Abstract: PURPOSE:To further improve a noise eliminating effect and to increase an oil pressure delivery amount by discharging air from an exhaust port through an exhaust passage, communicated to a second cylinder chamber, to the outside of a cylinder tube and locating a noise eliminating element in the exhaust passage. CONSTITUTION:An air pressure in a first cylinder chamber C is introduced to a second cylinder chamber D through an exhaust port T', a bleeder T1 communicated to the exhaust port, an air passage 32 partitioned by a ventilation cover 31, and a suction port R once. The introduced air pressure is discharged through an exhaust passage 33 of a pump housing 12A and a noise eliminating element 34 to the outside of a cylinder tube 1. When, as noted above, the air pressure in the first cylinder chamber C is discharged, it is delivered in a second cylinder chamber D through the air passage 32 once. Therefore, air pressures on both sides of a piston 2 are balanced with each other, and even when the noise eliminating element 34 is attached to an exhaust end part 33a, the influence of a back pressure is not exercised thereby. Only through the repulsion force of a spring 10 for return, the piston 2 can be lightly and rapidly returned.

Title: Electron source manufacture
Inventor: TAKAHASHI MASAYUKI
IPC: H01J9/02
Filed: 1988-10-07
Abstract: PURPOSE:To enable the discharge of H2O to be controlled, and thereby to enable cathode performance to be kept stably for a long time, by giving hydrogen treatment to a body structure in contact with a cathode. CONSTITUTION:Each vibration-proof member 53 for a filamentary cathode 51 is heat-treated with H2 having no effect on an oxide cathode for having an insulating material layer 53b occluded with the H2 so that the insulating material layer 53b is allowed to discharge the H2 when the filamentary cathode 51 ls heated. In this manner, as the insulating material layer 53b is originally occluded with H2O, the H2 is discharged to have no effect on the oxide cathode even with heating of the vibration-proof member 53, by heat-treating the vibration-proof member 53 to substitute for the H2O the H2 that is a molecule smaller than the H2O and has no effect on the oxide cathode. Thus, also gas being discharged with a rise of temperature in the vibration-proof member 53 is being changed from the to to the H2, and therefore the cathode can be prevented from the deterioration of its performance.

Inventor: YAMANISHI KOGETSU
IPC: B21D45/00
Filed: 1992-08-28
Abstract: PURPOSE:To prevent the generation of defects by detecting the failure in taking out a work clogging a trimming punch. CONSTITUTION:An oscillating body 11 which is driven for oscillation by means of a link 17 synchronizing with a ram 3 is attached with a contactor 14 composed of a conductive material in an insulated state, and an energizing circuit is formed in which the contactor 14 itself is made a switch between the contactor 14 and the ram 3. When the take-out process of the trimmed work (a) is completed and the ram 3 is retreated to a specified position, the contactor 14 is advanced to a detection position X in front of the trimming punch 5. With the work (a) clogging the trimming punch 5 and remaining due to failure in separating burrs (c) for example, the contactor 14 is brought into contact with the work (a) and thereby an electric current flows through the contactor 14, which is detected by an energizing sensor 20 to give out a detection signal. Consequently, the existence of the failure in taking out the work (a) is detected.

Title: Output control circuit
Inventor: MAENISHI KOZO
IPC: H03K17/60
Filed: 1985-11-13
Abstract: PURPOSE:To operate momentarily and stably an element to be driven by connecting an impedance element for positive feedback between either of a constant voltage circuit and a switching element for output control and a supply voltage detecting element. CONSTITUTION:When a supply voltage Ein rises from 0V slowly to reach a prescribed value, a transistor TR 2 is turned on. At this time a TR 3 is held in the turn-off state and an element Z to be driven is not operated. A TR 1 is held in the turn-off state also. When the voltage Ein rises furthermore, a TR 1 is turned on. As the result, the TR2 is turned off and the TR 3 is turned on to apply a voltage to the element Z. In this case, the TR 1 is switched from the turn-off state to the turn-on state momently and stably independently of minute rise of the voltage Ein because positive feedback is applied from a constant voltage circuit B to the base of the TR 1 through a resistor R4 for positive feedback. As the result, momentary output to the element Z is performed. When the voltage Ein falls, output to the element Z is stopped momentarily.

Abstract: PURPOSE:To inspect with hight accuracy the adhesion defect and lack of adhesive of the adhered part of the pellicle for a photomask and a pellicle frame and the coating defect and unequal coating of the tackiness agent on the inside wall surface of the frame by adopting the simple method for selectively observing the distribution of the fluorescent light by irradiating the pellicle with excitation light. CONSTITUTION:The light from a light source L which emits the light of visible rays from UV rays is passed through a excitation filter Fe which allows the selective transmission of only the excitation wavelength lambdaex intrinsic to the adhesive or tackiness agent used for the pellicle film P with the frame. If the pellicle P with the frame which is an object to be inspected is irradiated with this excitation wavelength lambdaex, a part thereof is absorbed by excitation and a fluorescent wavelength lambdaem is emitted. The excitation wavelength lambdaex which is passed straight through the object P to be inspected and is scattered by the same and the fluorescent wavelength lambdaem by the adhesive or tackiness agent are emitted by being mingled with each other. Only the fluorescent wavelength lambdaem is selected by an absorbing filter Fb. the part where the adhesive or tackiness agent exists is selectively viewed in this way.

Title: Remote supervisory and controlling equipment
Inventor: SATO AKIRA
IPC: H04L12/40
Filed: 1985-11-15
Abstract: PURPOSE:To almost simultaneously switch all of the slave stations connected in the faulty transmission direction to another transmission direction when a transmission line becomes faulty, by providing a looped transmission line by means of two pairs of transmission lines and hybrid transformers between a master station and slave stations and switching the transmission direction on the slave station side. CONSTITUTION:When a call signal is issued from a master station 10 to the slave station 20, the master station 10 detects the fault of the transmission line. At this time, the terminal station 20 switches its transmission line switches 25a and 25b on condition that it is impossible to receive the call signal from the master station 10. Therefore, the call signal is inputted through a clockwise transmission line 202 and the information signal of the terminal station 20 is transmitted to the master station 10 through a counterclockwise transmission line 102. After the switches 25a and 25b are switched, a special signal is sent from a transmitter 26. At the slave station 30, the special signal is detected with a detector 37 and transmission line switches 35a and 35b are switched. Since the slave station which receives a call signal from a transmission line being judged as faulty switches all its transmission lines in such way, the terminal station can make normal transmission.
