Title: Driving circuit
Inventor: HATAKAWA MAMORU
IPC: H03K17/62
Filed: 1982-09-13
Abstract: PURPOSE:To drive much loads with a small amount of power consumption, by connecting in series plural parallel circuits consisting of loads and switching elements and connecting these series circuits to a power supply to give the ON/ OFF control to the switching element. CONSTITUTION:A TR.TRi conducts with conduction of a switch Si. The light sent from each light emitting diode PDi is received by a phototransistor PTi for a photocoupler PCi. The signal sent from a joint between the PTi and a pull-up resistance RSi1 is supplied to a sequencer 1 via a line li. A TR1 is broken when a switch S1 is turned off, and a diode D1 and a light emitting diode PD1 are turned on. Therefore a TR PT1 conducts, and a signal of ''L'' is supplied to the sequencer 1. The TR.TR1 conducts when a switch S1 conducts, and a signal of ''H'' is supplied to the sequencer 1. The load current IL flowing to diodes Di and PDi can be reduced although the number of units is increased for the input circuit related to the switch Si since the base current IB1 of the TR.TR1 is very small. As a result the generation of heat due to a resistance RL, etc. can be suppressed.

Filed: 1982-09-16
Abstract: PURPOSE:To make the device thin in thickness, by designing the construction that the thickness of the device is only with the thickness from a DC motor directly coupled with a drive hub to a flat part of a plate spring fitted with a cone. CONSTITUTION:The cone 5 is fitted to the flat part 15 of the plate spring 13 and the thickness is not increased by plate spring 13, because the support of the plate spring 13 is lower than the flat part 15 with a tapered part 15. Since a cone lift arm 17 pressing the plate spring 13 presses the cone with its weight projection 24 by using te tapered part 16, the base 18 is taken as almost the same height as that of the flat part 15, and the cone lift arm 17 does not increase the thickness especially. The cone lift arm 17 is made thin with the pressing and the strength is ensured with a folding piece 22 bent downward. The stroke of the arm 17 itself is reduced and a door having a large stroke is used and the arm 17 is operated with the interlocking of them, then no hindrance is caused.

Filed: 1987-06-29
Abstract: PURPOSE:To make the next process operations smooth by connecting the tail of a hollow wire to a pressure air supply source, pressing a floating core in this hollow, and preventing the cut end of the hollow wire from larger deformation at the time of shearing. CONSTITUTION:A shearing die 4 and a supply hole 3 are provided at a shearing frame 1, and a long hollow wire a is inserted in the supply hole 3. A floating core 32 is set in this hollow wire slidably with air-tightness caused by an O-ring 33, and put in contact with a stationary core 30 of a swing plate at shearing, and with a slide plate affixed to the swing plate at swinging. From a pressure air source pressure air is supplied into the hollow wire a, and the floating core 32 is pressed to the stationary core 30 at the time of shearing. Accordingly retraction of the floating core caused by deformation of the cut end is prevented by the pressure force even though shearing force is applied to the hollow wire a. Thus deformation of the cut end is suppressed minimum to eliminate risk of generation of otherwise possible troubles at the next stage due to hooking etc.

Title: Magnetic recording medium
Inventor: YANAGIDA TAKAFUMI
IPC: G11B5/848
Filed: 1993-06-30
Abstract: PURPOSE:To obtain an excellent surface property by forming an upper layer from a magnetic coating material having 30wt.% solid content concn. and 100-500% creep deformation at 20+ or -1 deg.C liquid temp., and a lower layer from a magnetic coating material showing 20-1000% creep deformation on a supporting body. CONSTITUTION:The used magnetic coating material shows good dispersibility when the solid content concn. NV is 30wt.%, and thereby, creep deformation is also specified by using this NV as the reference. By specifying the creep deformation of the coating material for the upper layer and lower layer to 100-500% and 20-1000%, respectively, surface properties of the upper and lower coating layers are improved. Since the upper layer is designed for short wavelength and the lower layer for long wavelength, the dry film thickness of each layer is matched to the wavelength. The dry film thickness of the upper layer is preferably 0.01-0.5mum, and if it exceeds 0.5mum, recording density in a long wavelength region is decreased and the effect of the laminated structure is not obtd. When the dry film thickness of the upper layer is 0.01-0.5mum, sufficient recording is performed both in long wavelength and short wavelength.
