Title: Photo detector
Inventor: TOMITA KOUJI
IPC: H01L31/10
Filed: 1977-10-20
Abstract: PURPOSE: To increase the sensitivity of external outputs and spectral sensitivity regions by providing a PN junction in the group III-V compound semiconductor layer introduced with isoelectronic traps.  
     CONSTITUTION: A PN junction 2 is formed by using the crystal containing isoelectronic traps 1. Or a thin metal layer 3 such as of W, Au or the like is deposited to form a Schottky barrier 4. If with such constitution light 5 is radiated in the PN junction 2 or Schottky barrier 4, the absorption of photons by interband spacings takes place, forming electron-hole pairs 6. At the same time, the absorption of photons by the isoelectronic traps 1 also takes place, producing excitons 7. Hence, in the region where internal fields are strong such as in the space charge region of the PN junction 2 or the barrier 4, excitons 7 decompose to electrons 8 and holes 9, and the electrons 8 flow into the N type layer 10 and the holes 9 into the P type layer 11, generating photo current. This causes the external output to be increased by as much as the photons absorbed by the traps

Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To obtain the protection relay system which is well balanced between measurement errors of a current and a voltage and simpleness of device constitution by varying frequency characteristics of a band-pass filter with an external indication. SOLUTION: A microcomputer 10 is equipped with an indicating means which measures the frequency of a measurement signal and indicates frequency characteristics according to the measurement result.

Title: Recording member for information
Inventor: MIYAUCHI YASUSHI
IPC: G11B7/2405
Filed: 1994-06-09
Abstract: PURPOSE:To decrease the crosstalk and to surely reproduce information such as data and address by making the reflectivity from marks of a preformat area and ROM area to be <=5%. CONSTITUTION:A ZnS-SiO2 protective layer 2 of about 90nm thickness is formed on a polycarbonate substrate 1 having 13cm diameter and 1.2mm thickness, on which a Ge22Sb22Te55Co1 recording film 3 of 30nm thickness is formed. The recording film is subjected to sputter etching with Ar ion to decrease the film thickness in the projection part of the fine rugged pattern of the recording film on an embedded mark to obtain of the recording film about 10nm average remaining film thickness on the embedded mark. Then, a ZnS-SiO2 intermediate layer 4 of 40nm thickness is formed, on which an Al-Ti reflecting layer 5 of 100nm thickness is formed. Then, a UV-curing resin layer 6 is applied to obtain a disk. Disks having the same structure are stuck to each other with a hot-melt adhesive 7. Thus, both of lands and grooves formed on surfaces of substrates 1, 1' can be used as tracks for information recording. Reflectivity from the preformat area in the adjacent track or embedded marks of ROM area can be decreased and the crosstalk can be decreased.

Title: Uncoiler
Inventor: OBARA MAKOTO
IPC: B65H18/04
Filed: 1980-09-16
Abstract: PURPOSE:To hold the position of an expanded drum of an uncoiler at an optional position, by detecting the position of a rotary cylinder, and by controlling this position of the rotary cylinder. CONSTITUTION:If the uncoiling process comes to an ending stage, and the residual number of turns of a coil 1 becomes small, the slip of a drum shaft 3 against the coil 1 gradually increases because of the reduced friction force between the drum shaft 3 and the coil 1. With this increase of the slip, a piston 11 of a rotary cylinder 10 also displaces. This displacement of the piston 11 is detected by a differential transformer 14 whose output is sent out as a feedback to a hydraulic circuit which then automatically controls the output pressure of a pressure control unit 15. Hereby, the oil pressure is controlled so as to always keep the diaplacement of the piston 11 due to the reduction of the number of turns through an uncoiling process at a prescribed position, so that the coil layers do not cause mutual slip and the coil 1 is not injured; as a result, a good uncoiling process is performed.

Title: Economizer for running energy of vehicle
Inventor: TOTSUKA SUSUMU
IPC: B60K17/04
Filed: 1980-09-13
Abstract: PURPOSE: To reduce the consumption of fuel and economize running energy, by dividing the gravity of an automobile and the load thereon into components in prescribed directions in the running of the automobile to perform the running on flat ground under the same conditions as running on a slope.  
     CONSTITUTION: When the gravity of load on a body 1 has increased or a cargo is jolted after shifting to running, the height of an axle 3 does not change but a chassis 2 is pushed down because a spring 11 is stiffer than another spring 7 and carries most of the gravity of the body 1. At that time, the gravity of load on a drive shaft 8 is transferred onto the axle 3 through a gear box 14 to apply such a force that the drive shaft 8 pulls the axle 3. Because of the action of the force, an automobile on horizontal ground is run by the same energy as required for running on a downward slope with a gradient angle of θ. The running energy is thus economized.

Title: Surface acoustic wave resonating type filter
Inventor: TAKEMA TAKEMITSU
IPC: H03H3/08
Filed: 1987-05-27
Abstract: PURPOSE:To improve the reflecting efficiency of the titled filter, by forming both ends of each conductor stripe forming a reflector in such a way that a connected and opened states are alternately formed successively at every stripe, with the states being reversed at every stripe against both ends of adjacent conductor stripes. CONSTITUTION:Both ends of each conductor stripe forming a reflector 2a are formed in such a way that a connected and opened states are alternately formed successively at every stripe, with the state being reversed at every stripe against both ends of adjacent conductor stripes. This reflector 2a thus formed is used as an impedance matching inductance element by electrically connecting the reflector 2a with interdigital electrodes 1 and connecting an input or output terminal with the reflector 2a thus connected. Since no area surrounded by electrode patterns exists when such constitution is used, an etching solution can uniformly penetrate into an etching area and the shape forming accuracy of the conductor stripes is improved. As a result, the reflecting efficiency is improved.
