Title: Tape end detecting device
Inventor: ANDO MASAHIRO
IPC: G11B15/08
Filed: 1986-06-23
Abstract: PURPOSE:To obtain a tape end detecting device with less part numbers at low cost by equipping an optical reflection member at the inner side pinching a tape and the light emitting and receiving elements installed at the position opposing to the optical reflection member of the external side pinching the tape and on which a light emitting part and light receiving part are set up via a light shielding member. CONSTITUTION:The light emitted from a light emitting element 4 according to the pulse signal generated from a pulse signal generater 15 transmits a light, since a magnetic layer is not formed on the part 14b of the start or finish which is the end of a tape 14. With the arrival of the end part 14b the light is reflected by the mirror 1 of the center, coming into a light receiving element 5 and the start and finish end of the tape are detected. The AC signal generated from a light receiving element 5 is fed to a tape running stopping circuit 17 after the DC conponent is removed by a DC component removing circuit 16. A package element 2 is made by arranging so that the light emitted from the light emitting element 4 may not be leaked directly into the light receiving element 5 with a light shielding plate 6.

Title: Emitter coupling logic circuit device
Inventor: NISHIMURA TAKASHI
IPC: H03K19/086
Filed: 1990-06-01
Abstract: PURPOSE:To reduce power consumption by providing a PNP transistor(TR) controlling a bias level for a current source for each current supply of a switching and emitter follower in response to an input logic level and an impedance element adjusting its level and current to the circuit device. CONSTITUTION:An ECL circuit device acts like a conventional ECL circuit when an input level is low. When the input level Vin reaches a level VH higher than a reference level VBB, an input TR Q1 is conductive and a TR Q2 transits to a nonconductive state. In this case, a potential of emitters of the TRs Q1, Q2 connected in common rises from VBB-VBE to a potential VH-VBF being a level VE decreased by a base-emitter forward voltage VBE. As a result, a base potential of a PNP TR Q6 rises and a current flowing to a resistor R6 generating a bias potential is decreased. Thus, the switching current and the emitter follower current are decreased to zero or equivalent thereto.

Title: Piezoelectric type acceleration sensor
Inventor: KUNIMURA SATOSHI
IPC: G01P15/09
Filed: 1989-06-08
Abstract: PURPOSE:To make it possible to make a structure simple and compact and to decrease cross talk by laminating a stage, a film-shaped piezoelectric body and a load body, constituting a sensor, and forming a driving battery as a part of the load body. CONSTITUTION:A sensor 11 is composed of a stage 12, a film-shaped piezoelectric body 13 and a load body 14. The piezoelectric body 13 is fixed to the measuring surface of the stage 12 which is orthogonal to a sensitive axis G. The load body 14 is fixed to the piezoelectric body 13. Thus an inertial mass part is formed. A circuit for processing the electric output from the piezoelectric body 13 is mounted on a circuit board 17. The circuit board 17 is attached to the lower surface of the stage 12. The load body 14 is composed of a driving button-type battery 23, a mounting plate 24 and a strip-shaped battery holder 25. The symmetrical axis of the load body 14 is made to agree with the symmetrical center of the piezoelectric body 13. In this constitution, even if acceleration other than the direction of the sensitive axis is applied, compressing force and tensile force having the equal magnitude act on the piezoelectric body 13. Therefore, cross talk is less. Since the processing circuit and the driving battery are contained in a package 15, the SN ratio is high, and the acceler ation in the direction of the sensitive axis G can be measured with the simple structure.

Abstract: PURPOSE:To obtain an efficient stepless speed change gear by driving a hydraulic pump by a power shaft of a planetary gear arrangement and rotating  and controlling the internal tooth rings by a hydraulic motor driven by a pump. CONSTITUTION:When a hydraulic pump 8 connected to a power shaft 6 is actuated to supply pressurized oil to a hydraulic motor 14, and a pinion 6 provided on an output shaft 15 of the hydraulic motor 14 is rotated from the stop condition toward a direction of E1, a ring-shaped gear 10 is rotated toward a direction D2.

Abstract: PURPOSE:To form a fine pattern having more stable reliability by forming a metal material on a semiconductor substrate by sputtering, etching a metal layer by wet etching, and then coating it with positive type photoresist. CONSTITUTION:An aluminum layer is formed on a semiconductor substrate having a step of a base by sputtering, and the surface is wet etched by an etchant in which suitable amounts of acetic acid and nitric acid are added to phosphoric acid. Then, the etchant etches the aluminum layer 11 along the particle lump in the aluminum to intensify grains like 13 on the aluminum layer to be relieved. When the grains 13 are exposed, scattering of the light is suppressed to eliminate reflecting notching at a positive type photoresist 12. Thus, notch, disconnection of aluminum wiring due to reflecting notching of the photoresist after the aluminum is photoetched can be prevented.
