Abstract: PURPOSE:To enhance watertightness accuracy by simply bonding resin members different in material quality without generating the lowering in bonding strength, by providing a wedge-shaped projection to the surface of the high m.p. resin member of two resin members having different melting points and applying heat to the low m.p. resin member at the temp. between the melting points of both resin members and pressing the projection to the surface of the low m.p. resin member. CONSTITUTION:The side surface shape of the projection 1a provided to the surface of a high m.p. resin member 1 is formed in an inverted wedge shape to recess 1b the joint of the projection 1a. A hot plate 5 is placed on the surface of the low m.p. resin member 2 on a receiving jig 4 and heat exceeding the m.p. of the resin member 2 is applied to the surface of the resin member 2. At this time, the temp. of the hot plate 5 is controlled so that temp. melting the resin member 2 is set so as to be lower than m.p. of the resin member 1. After a molten part 2a is generated on the resin member 2, the hot plate 5 is moved in a horizontal direction and a jig upper mold 3 is moved and the projection 1a is abutted to the molten part 2a to be pressed thereto. When the molten part 2a is solidified, the projection 1a bites into the molten part 2a in a wedge shape.

IPC: H01C7/00
Filed: 1993-06-08
Abstract: PURPOSE:To ensure appropriate resistance characteristics by firing simultaneously and integrally a board, a conductor layer, and a resistor layer containing a ruthenium compound of specified average particle size having a glass matrix containing bismuth oxide thereby preventing the ruthenium compound from being diffused into the glass. CONSTITUTION:A resistor layer and a conductor layer are arranged on a board and then they are molded integrally and simultaneously.

The conductive particle, i.e., the ruthenium compound particle, preferably has average particle size in the range of 0.01-0.4mum. Larger particle size increases noise and voltage coefficient and smaller particle size accelerates aggregation of resistor paste. The metal particles providing the basic composition of the conductor layer includes Ag particles or Ag alloy particles, for example. This composition realizes a wiring board having easily and accurately controllable resistance.

Abstract: PURPOSE: To provide a desired control over a heating power by a method wherein a flow rate of gas in respect to a combustion part is controlling by opening or closing an auxiliary valve to be operated by operating the knob.  
     CONSTITUTION: When the knob 8 is rotated up to a "high" position, gas flowed into the intermediate gas passage 29 is supplied to an expansion case 38 through both nozzles 35a, 35b due to the fact that the auxiliary valve part 37 is kept opened, and then injected into the combustion space through a gas conducting pipe 49. In turn, when the knob 8 is changed over to a "low" position, a depressing pressure of the lever 40 against the valve rod 39 of the auxiliary valve part  37 is released in cooperation with a rotation of the knob 8, so that the valve  body 37b closes the vave port 37a. Suuplying of gas to the combustion space is  performed only at one gas discharge part 35. Thereby, when the knob 8 is set  to a "high" position, a high heating power condition can be reaized and, in turn,  when the knob 8 is set to a "low" position, a low heating condition can be obtained.

Title: Writing and reading circuit of magnetic storage device
Inventor: SADA YUTAKA
IPC: G11B5/02
Filed: 1984-08-07
Abstract: PURPOSE:To prevent a transistor (TR) of a reading circuit from breaking down and to evade deterioration in characteristics by connecting a series circuit of a forward diode and a Zener diode between a power source and each head terminal, and connecting a resistance between the power source and each head terminal and between both head terminals. CONSTITUTION:A transistor TR209 is saturated and the potential at a terminal 222 drops in a write state wherein a magnetic head 220 has a break of wire to cause TRs 206 and 209 to turn on and TRs 207 and 208 to turn off. When the forward voltage of the diode is VF and the breakdown voltage of the emitter junction of a TR is BVEB, the Zener diode 225 breaks down if the voltage V1 of the head 222 ries up to -VF-BVES, so that the voltage V1 is clamped at -VF-BVES. An input TR218 breaks down when the potential difference between head terminals 221 and 222 attains to VF+BVEB, but the difference in breakdown voltage between the emitter junction of the input TR and Zener diode is small, so the input TR is protected securely. This circuit is therefore suitable for IC-implementation.
