Title: Method for growing semiconductor thin film
Inventor: OKAMOTO AKIHIKO
IPC: H01L21/205
Filed: 1987-10-01
Abstract: PURPOSE:To reduce fluctuation of conductance and to improve controllability of thin film growth, by employing such structure as material gas in a gas conduit is maintained in molecule flow. CONSTITUTION:Gas material is discharged through a gas lead-in port to a substrate 11 under vacuum so as to grow a semiconductor film. The gas material in a gas conduit between a needle valve 5 or a mass flow controller and the outlet of gas lead-in pipe 1 is maintained in molecule flow. Consequently, conductance of the gas lead-in pipe 1 depends only on the thermal motion speed of gas and does not depend on the viscosity coefficient and the average pressure of gas. When compared with the case where gas in the gas lead-in pipe 1 is maintained in viscous flow, fluctuation of conductance is suppressed and controllability of film growth is improved.

Title: Semiconductor switching element
Inventor: NISHIZAWA JUNICHI
IPC: H01L29/744
Filed: 1987-10-02
Abstract: PURPOSE:To enable high speed switching without increasing ON-voltage, by making the width of an anode short region in an anode short structure narrower than the interval between mutually adjacent anode regions. CONSTITUTION:An anode (anode region) 11 composed of a P<+> type semiconductor layer, and an anode short region 12 composed of an N<+> type semiconductor layer are alternately arranged on an anode electrode 9 in the manner in which the width w2 of the anode short region 12 becomes narrower than the interval w5 between the mutually adjacent anodes 11 (w2<w5). That is, between the anode short region 12 and the anodes which are adjacent on both sides of the anode short region 12, gap regions 13a, 13b composed of N<-> layers are arranged. Therefore, short resistance can be made large at the time of turn-ON, and small at the time of turn-OFF, As a result, turn-ON and turn-OFF are rapidly performed, and further the injection amount of hole is large even in the state of ON. Thereby enabling the high speed switching without increasing ON voltage.

Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain a highly hydrophilic highly biocompatible molding by forming on the surface of a molding a hydrophilic layer comprising a polymerizable compound having a hydrophilic group except a heparin residue and a polymerizable compound having a heparin residue. SOLUTION: The polymerizable compound (A) having a hydrophilic group except a heparin residue is a polymerizable compound having a hydrophilic group such as a sulfone group, a quat. ammonium group, or a carboxyl group, and the polymerizable compound (B) having a heparin residue is a heparin derivative of the formula (wherein R is a direct bond, -O-, -CONHCH2CH2O-, or the like; and Hep is a heparin residue). A hydrophobic photopolymerizable composition is molded into a shaping, and the shaping is brought into contact with a hydrophilic liquid containing components A and B and irradiated with an actinic light, whereupon the shaping is cured, and the hydrophobic compound and the hydrophilic compound are copolymerized at the interface between the shaping and the hydrophilic liquid to chemically bond molecules of the hydrophilic compound to the surface.  No photopolymerization reaction takes place in the hydrophilic liquid except the interface of contact. The surface- hydrophilic molding does not suffer from swelling.

Title: Unmanned traveling device
Inventor: TAKIGUCHI YUJI
IPC: B62D1/24
Filed: 1986-10-21
Abstract: PURPOSE:To ensure the uniform drive of a traveling device within a room with high efficiency without using any guide line nor any effect caused by the recesses/projections of a wall surface, etc., by producing the lateral displacement control output so as to secure the set distance value from the wall surface to give it to a steering means for control of both front and rear steering wheels and at the same time giving no said control output at the time of control of inertia navigation. CONSTITUTION:The distance sensors 3 and 3' are attached to the side face of an unmanned traveling device main body 2 to detect the wall surface along the traveling direction. Thus, the relative angle between the main body 2 and a wall 1 is obtained together with the distance between the body 2 and the wall 1 based on the detection outputs of sensors 3 and 3'. Then DELTAy is approximated to a traveling reference 5 so that said relative angle DELTAtheta is set at zero with the distance from the wall surface kept constant as long as the relative angle is kept within the prescribed value. While the main body 2 is driven straight by the inertia navigation based on the gyro output data in case the relative angle is larger than the prescribed value, the distance measurement is impossible or the distance measurement data 3a and 3b of both sensors 3 and 3' have large changes.

IPC: B62J17/00
Filed: 1987-10-03
Abstract: PURPOSE: To increase the air flow velocity from a rear end blowout port by branching the front part of a ventilation duct to a vertically forked form, and opening its front end air intake port toward the front of a body so as to face a fairing surface. CONSTITUTION: The front part of a lower ventilation duct 26 to be integrated into a fairing is vertically branched to provide an upper branch cylinder 27 and a lower branch cylinder 29. Thus, two air intake ports 28, 30 can be formed to catch a running wind through them. Therefore, even if the opening are of each intake port can not be extended in the structure of the fairing, the substantial air intake area of the lower ventilation duct 26 can be increased. Consequently, the air having a high flow velocity can be taken out from a first air blowout port 32 and a second air blowout port 33. When a cutoff valve 36 is closed, particularly, a higher air velocity can be provided from the air blowout port 32.

The spring 12 is supported so that the position perpendicular to a line SA parallel with a seat slide angle passing through a hip point HP and dropped from the hip point HP to this perpendicular direction can become a center 14. Namely, the spring is supported on the frame 13 so that a front side dimension (a) can be coincident with a rear side dimension (b). Thus, since the hip point is almost coincident with the bending center of spring of the seat cushion, forward sliding is not generated.
