Title: Cathode-ray tube
Inventor: KOJIMA TOSHIKUNI
IPC: H01J29/88
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To solve the problems in the conventional device that the deflection power of an electron beam increases accompanying the reduction in the full- length of a cathode-ray tube, the angle of incidence of the electron beam on a color selection mechanism becomes acute, and miss-landing due to doming, magnetic field and the like increases. SOLUTION: An electrostatic lens is formed with setting different potentials without generating a discharge, a charge and the like because a mixture of aluminum oxide and titanium oxide or ruthenium oxide is used for an inner conductive film inside a cathode-ray tube. A track of an electron beam is designed at will.

Title: User identification system
Inventor: SAKAMAKI MASASHI
IPC: G06F1/00
Filed: 1990-10-04
Abstract: PURPOSE:To prevent an illicit access cause by the leakage of a password by registering previously not only the password but the character input interval. CONSTITUTION:A conincidence deciding device 6 decides the coincidence between the character input intervals of passwords as well as the coincidence between the passwords. A monitoring device 3 monitors the character input intervals as the time when a user inputs a password to a terminal equipment 2. Meanwhile the input character intervals are ciphered and registered previously by a registering device 7. Then the coincidence is decided by a coincidence deciding device 6 between the registered character input intervals and those of the password inputted by the user. Thus the grant to an illicit access caused by the leakage of the password only can be evaded.

Title: Nozzle piece for cleaner
Inventor: OSHIMA IKUO
IPC: A47L9/06
Filed: 1987-10-22
Abstract: PURPOSE: To prevent the lowering of a dust suction force because of a drop in vacuum by making an adjusting body stick out into a suction groove interlocking a protruding action of bristles from the bottom surface of a suction port to reduce the sectional area of an opening at an end in the suction groove. CONSTITUTION: When bristles 17A and 17B are made to stick out from the bottom surface of a suction port body 11, an adjusting body 34 which is provided integrally on a brush body 15 is made to stick out into a section groove 31 to prevent the lowering of vacuum degree. The adjusting body 34 closes a front half or a rear half of the suction groove 31 to allow the reducing of the opening sectional area of the suction groove 31. As a result, the adjusting body 34 has a plane formed flush with the bottom surface of the suction port body 11 without completely closing the opening 32 at the end part of the suction groove 31. This suppresses the swelling of a tatami (rush) mat or the like by a suction pressure with the tip part of the adjusting body 34, thereby preventing the narrowing of the sectional area of the opening of the suction groove 31.

Title: Optical logic integrated element
Inventor: OKOCHI SHUNSUKE
IPC: H01S5/00
Filed: 1987-10-22
Abstract: PURPOSE:To obtain a NOR gate having a large extinction ratio by laminating a photodetector on the upper part of other part than the waveguide of a semiconductor laser, and providing an electrode terminal being common to the semiconductor laser and the photodetector. CONSTITUTION:A NOR gate of an optical input/output is obtained by laminating a phototransistor on the upper part of other part than the waveguide of a semiconductor laser, and applying a prescribed bias of positive and negative to an electrode terminal 12 being common to the semiconductor laser and the phototransistor, and a semiconductor laser (n) side electrode 14 and an emitter electrode 13, respectively. Subsequently, a current source which is connected to the common electrode terminal 12 is controlled so that an injection current to the semiconductor laser becomes a little larger than an oscillation threshold current. This state is a state of no-input, and with respect to an optical input '0', an optical input '1' of the semiconductor laser is obtained. Next, when an optical input exists in the phototransistor, a current flows between a collector and an emitter, the current injected to the semiconductor decreases, the oscillation stops, and the output goes to '0'. In such a way, an extinction ratio can be made large.

Abstract: PURPOSE:To prevent deficiency of a region in a contact hole at the time when dopant ions is implanted, by depositing a conductive thin film on a contact hole which has been formed previously and implanting dopant ions through the conductive thin film. CONSTITUTION:Following to the formation of a contact hole 23, a conductive thin film 24 is formed. Dopant ions 25 are then implanted through the conductive thin film 24 in the contact hole 23.

Title: Control circuit
Inventor: HIROSAKI YOSHIHIKO
IPC: H02H3/16
Filed: 1992-10-06
Abstract: PURPOSE:To prevent a high impedance relay from its unnecessary operation by arranging a Zener diode, which impedes operation of the high impedance relay before generating predetermined voltage, between a signal contact and the high impedance relay. CONSTITUTION:Characteristic voltage of a Zener diode 5 is set to a voltage value of 50V or more, for instance, 55V 1/2 the control voltage. Accordingly, at the time of generating a complete earth in a point A, voltages applied to an earth detecting relay 2 and a high impedance relay 4 are respectively 50V. However, the high impedance relay 4 is not actuated because it is connected through the Zener diode 5 of voltage characteristic 55V, and only the earth detecting relay is actuated to generate an alarm. That is, the high impedance relay 4 is actuated by only voltage of 55V or more, and by only the drive voltage via a signal contact 3. In this way, unnecessary action of the high impedance relay 4 can be prevented.
