Filed: 1985-03-13
Abstract: PURPOSE:To improve wear resistance by using Fe3O4 and Fe for the essential components of columnar structural particles and specifying the ratio of Fe with respect to Fe3O4. CONSTITUTION:A vertical magnetic recording medium is constituted by laminating a magnetic layer 3 consisting of the columnar structural particles 1 oriented perpendicularly to the substrate plane and gaps 2 on the substrate 4. The essential components of the columnar structural particles consist of Fe3O4 and Fe, in which the ratio of Fe with respect to Fe3O4 is >=7.5% and <100% by weight. The ratio dw/dv between the film thickness dw by weight and film thickness dv by volume of the magnetic layer is made >=0.44 and <=0.93. The thickness of the magnetic layer is preferably in a 0.05-2.0mum range when a head touch and the forming speed of the magnetic layer are taken into consideration. Gas having small chemical activity such as gaseous nitrogen is introduced simultaneously in addition to oxygen into a vapor deposition atmosphere and the pressure of the vapor deposition atmosphere is set under a high pressure in the stage of forming the magnetic layer. The vertical magnetic recording medium having high saturation magnetization and excellent wear resistance is thus obtd.

Filed: 1983-03-24
Abstract: PURPOSE:To facilitate control of an emitter resistance by changing the relation between the emitter resistance of a transistor for an emitter follower and the conductance of an oscillating circuit for a proximity switch. CONSTITUTION:A transistor TR4 of an emitter follower is provided in parallel to a TR1. The collector of the TR4 is connected to the collector of a TR3 of a current mirror circuit 5, and the emitter of the TR4 is connected to an end of a variable resistor R. The other end of the resistor R is connected to the emitter of the TR1, and the mobile terminal of the R is earthed. The resistance values are defined as Re1 and Re2 between the earth of the R and the emitters of TR1 and TR4 respectively. The TR3 and TR4 of such an oscillating circuit function as transistors at the positive and negative feedback sides respectively. Therefore the conductance is set as Gi=-(1/Re1-1/Re2) when the oscillating circuit is viewed from the side of a resonance circuit. Then the conductance Gi is set at 0 with Re1=Re2, and no oscillation is generated unless the Gi value is positive. Thus the resistance value is controlled within a range of Re1>Re2, thereby facilitating control of the detecting position.

Title: Driver circuit, low noise driver circuit and low noise low vibration driver-receiver circuit
Inventor: CHII RIAN CHIEN
IPC: H03K17/687
Filed: 1992-03-06
Abstract: PURPOSE: To realize an OCD circuit that utilizes reduced output voltage which switch for minimizing an OCD output noise. CONSTITUTION: N-channel and p-channel transistors(TRs), configuring an OCD circuit 10 as a couple of complementary field effect TRs connected in non- inverting series circuit arrangement boost a driver output up to a positive power supply voltage smaller than a threshold voltage drop across the n-channel TR and decrease the output within a threshold voltage of a ground level with respect to an inverse circuit transition, so as to reduce vibration of the output. An n(p) well of the p(n) channel TR is connected to an output node, to eliminate a base effect of one or both the TRs. Since the rise time and the fall time of the output signal is controlled by the OCD circuit 10, collapse due to power supply is reduced.

Title: Production of metal piece continuous body of easy separation
Inventor: GOKAN TAKANARI
IPC: B21D28/10
Filed: 1979-04-20
Abstract: PURPOSE: To obtain the captioned product such as easy-to-open can cap without requiring bonding or the like of metal pieces by giving shearing pre-strain to a metal plate at the stroke below its thickness and further giving the shearing pre-strain in the opposite direction at said stroke.  
     CONSTITUTION: An upper blade 2 and lower blade 3 are disposed on both sides of a metal plate 1 with a clearance G being made small or zero. The lower blade 3 is fixed and only the upper blade 2 is moved perpendicularly downward. The metal plate 1 between the both blades is pressed and fixed by a clamp 4. Thence, when shearing pre-strain is given to the metal plate 1 at the stroke L below its thickness, an easy-to-separate region 5 is formed. This easy-to-separate region 5 receives strong shearing strain and the crystal grains are crushed to become fibrous. Hence, this portion is work-hardened but if shearing stress or the stress close thereto is given thereto in the direction opposite from the strain having been given, it is readily ruptured and separated by small stress such as hand.

Abstract: PURPOSE:To prevent the kitchen dust from forming mud so as to be discharged into the drain and shortens the dust crushing time by forming the stationary blade of the kitchen disposer to project partially and cubically from the inner peripheral surface, and thus providing a clearance between the rotary blade. CONSTITUTION:A belt-shaped and annular stationary blade 15 is projected partically on the inner peripheral surface to form a cutting part 15b so that the distance between the adjacent parts 15b will be larger than that of adjacent cut-off parts 15a. The kitchen dust pressed against the inner surface of the stationary blade 15 enters the clearance between the cutting part 15b and the cut-off part 15a to be crushed by both the rotary and stationary blades 37 and 15. Thus, in this crushing structure wherein the crushing diameter Y' is large and the cutting part 15b is projected inside, the clearance between the rotary and stationary blades 37 and 15 prevents the dust from forming mud when crushed. According to this disposer, the dust can easily enter the cutting part 15b and the disposing time can be shortened.
