Title: Spiral composite pipe
Inventor: ENOMOTO SEIICHI
IPC: B32B1/08
Filed: 1991-01-16
Abstract: PURPOSE:To provide a composite pipe having a resin layer forming structure where peeling is extremely difficult to occur and improves durability by partially forming a given gap in a weld part to form a plurality of non-weld parts, and causing resin to leak in a hole formed by the non-weld parts. CONSTITUTION:A composite pipe is formed such that, in a state that a beltform metallic sheet 10 is spirally wound, adjoining side edges are welded together to form a metallic pipe 1 the inner peripheral surface of which is covered with resin. A plurality of non-weld parts 12 are partially formed in a weld part 11 of the metallic pipe 1 at intervals of a given gap, and covering resin is caused to lead in a hole formed by the non-weld part 12. An anchor effect is produced as a result of resin entering the non-weld parts 12 formed in the middle of the weld part 11. Anchor parts produced by leakage of the resin are scattered throughout the overall length of the pipe and in a peripheral direction. Even when partial peel of resin occurs, there is entirely no fear of expansion enough for closing of a pipe occurring, contraction of a resin pipe hardly occurs, and slip off of the resin pipe is also prevented from occurring.

Title: Schottky barrier diode with contact for evaluation
Inventor: KIKUCHI KENICHI
IPC: H01L21/66
Filed: 1979-01-12
Abstract: PURPOSE: To evaluate the portion for practical use by a method wherein a contact for evaluation is provided sufficiently near the contact for actual use to measure electrical characteristics.  
     CONSTITUTION: Items for evaluating a wafer before assembly are a performance  index Δn, inverse break-down voltage VB, resistance in series RS, junction capacity  Cj, etc. of each contact for actual use. These depend on the carrier density and  thickness of a semiconductor epitaxial layer. Although the density and thickness of  the layer are different according to the position, the difference is mild within the  wafer surface, for instance, each of the contact portions in the neighborhood of  about 100μm has almost the same values, and the electrical characteristics are  practically the same. Therefore, in addition to contact portions for actual use, a  Schottky barrier contact for evaluation is provided separately. If the evaluation of  the contact for actual use is made on the basis of the electrical characteristics, waste  of the cost for assembling chips can be saved.

IPC: G11B19/02
Filed: 1986-01-10
Abstract: PURPOSE:To simplify the constitution of a circuit and to reduce the cost of a device by changing the values of time setting capacitors and resistors by a switching circuit to be driven in accordance with a signal instructing a recording state. CONSTITUTION:At the start and end of a signal WG instructing the recording operation state, a monostable multivibrator circuit MM is driven. At the start of operation, a PNP transistor (TR) is turned on through an inverter G5 and resistors R5, R6. The time t1 is expressed by the equation of t1= K.C1.R2.R3/(R2+R3) when K is a constant. At the end of the operation, the PNP TR is turned off and the time t2 is expressed by t2=K.C1.R2. Thus, the circuit MM operates so as to switch the delay time setting constant by the switching circuit to be driven in accordance with the signal WG instructing the recording operation state, so that the number of parts can be reduced. When these circuits are to be constituted by integrated circuits, the number of circuit elements can be reduced.

Filed: 1978-01-17
Abstract: PURPOSE: To make it possible to accomplish the stable automatic focusing operation, while facilitating the adjustment of an optical system, by using a semiconductor laser as a light source to vibrate the same in the direction of the optical axis.  
     CONSTITUTION: The laser beam 2 from a semiconductor laser is condensed upon the surface of a video disc 4 by the action of an objective lens 3. The reflected light is into a light emitting portion of the laser 14 so that the resultantly varied output of the laser 14 is subjected to signal processing at 16, after it is optically detected at 8, thereby to effect a video reproduction. In this instance, the oscillator 11 excites a vibrator 9 so that the laser 14 is vibrated with a preset frequency f in the optical axis direction. As a result, the frequency f is inverted in phase in the displacement of the surface of the disc 4 from the focal point of the lens 3, and the lens 3 is moved in the direction of arrow A through an actuator 13 by the output which is produced by effecting the phase detection of the output of the detector 8 so that the focusing operation can be automatically.
