Title: Rotary scanning type position detector
Inventor: SAWAMURA HARUMICHI
IPC: G01B11/00
Filed: 1982-02-22
Abstract: PURPOSE:To make mounting on working points and working planes easy and to detect positions in a wide range by disposing a scanning signal transmitter which outputs rotating signals and >=3 pieces of scanning signal receivers on the sample plane and processing the received signals of the receivers arithmetically. CONSTITUTION:The rotary scanning signal of an angular speed omega of a rotating signal oscillator P is detected with the receivers D1-D3 fixed in the working plane of the P and the peak values of the output signals thereof are detected in a detection part H and are fed to a scanning angle detection part J. On the other hand, the angular speed signal from an output part K which applies the rotary scanning signal is fed to the part J, by which the vertical angles (angles of circumference) theta12, theta23 of DELTAPD1D2, DELTAPD2D3 are determined from the product  of the respective detected time differences DELTA12, DELTA23 and omega. The position of the point P is determined as the intersected point of the circles O12, O23 past the 3 points PD1D2 and PD2D3 in an arithmetic part C, and the position information of the point P is outputted to a position information output part S. The mounting on the working points and working planes is thus easy and the positions in a wide range are detected.

Title: Level control circuit
Inventor: SATOU KATSUYUKI
IPC: H03G11/00
Filed: 1980-03-07
Abstract: PURPOSE:To obtain a level control circuit than can realize a low power consumption and high-speed reading, by forming a voltage dividing circuit having a feedback function with the depression-type MISFET and others and limiting the voltage of a memory matrix input/output line at a certain level. CONSTITUTION:The common input/output line DCOM and anti-DCOM of the static memory cells 1a arranged in a matrix are connected to a voltage dividing circuit consisting of the depression-type MISFETQ17, Q18 and others that receive the voltage of the other end of the serial resistances R1 and R2 with one end connected to the source respectively. A feedback control is given to the conductance of each of the FETQ15 and Q17 which vary their bias diretions due to the variation of the voltage drop of the resistances R1 and R2 in accordance with the levels of the line CDM and anti-CDM corresponding to the storage contents of the selected cells 1a-. Thus the output impedance before the read signal is supplied to the voltage dividing circuit is increased to reduce the power consumption, and at the same time the input voltage is limited at a certain level by a low output impedance to realize a high-speed reading. Such level control circuit can be obtained.

Title: Boom of sailing device
Inventor: IWAMURA SATORU
IPC: B63B35/79
Filed: 1982-02-22
Abstract: PURPOSE:To make a bow-shaped boom into the minimum weight and a structure with rigidity in such a way that the boom is composed of two big and small pipes, and the small pipe is inserted only at its center part into the big pipe. CONSTITUTION:A boom 3 is composed of a big pipe 31 and a small pipe 32, the small pipe 32 is inserted only within the determined range of its center part into the big pipe 31, and they are overlapped and jointed to each other. The outer diameter of the small pipe is made almost the same as the inner diameter of the big pipe so that no play may be allowed at their joint parts, and both are joined with rivets etc. In consequence, extension of the sail gives bending moment to a bow-shaped boom 3, and the magnitude of said moment is made larger as it goes to the center part, but as the center part is made into a dual pipe, and its rigidity is made larger, it can sufficiently endure the movement, and because the both end sides subjected to a small bending moment are made of a thin pipe, increase of the weight is limited.

Title: Method of fabricating semiconductor element
Inventor: OKA NOBUTAMI
IPC: H01L21/316
Filed: 1979-03-13
Abstract: PURPOSE:To reduce reverse leakage current of a semiconductor element by coating a glass powder layer on the surface of a semiconductor substrate, calcining the layer in atmosphere containing steam to form a glass film thereon and thus eliminating air bubbles and pin-holes in the surface stabilizing film. CONSTITUTION:A lead or zinc series glass powder layer 4 is coated on the exposed surface 3 of the PN junction 2 of a semiconductor substrate 1. The layer is heated in mixture gas of nitrogen, oxygen containing steam or nitrogen and oxygen to melt and calcine the glass powder so as to form a glass film 34 thereon. Since the vapors form SiO2 on the silicon surface of the substrate at their melting time in this process, the wetness of the glass becomes good to preferably flow the glass on the surface of the substrate so as to eliminate air bubbles. The SiO2 on the surface of the substrate is finally molten in the glass film. Since negative charge of Al2O3 or PbO in glass is, on the other hand, neutralized with positive chage of the SiO2, leakage current is reduced.

Title: Reel mechanism of magnetic recording tape forwarding device
Inventor: NAKAO HISAHIRO
IPC: G11B15/44
Filed: 1980-03-07
Abstract: PURPOSE:To ensure an assured forwarding at a constant speed, fast winding and other actions of a magnetic tape by means of a two-way DC motor, by giving a control the attachment/detachment of the turning action between the 1st and 2nd rotary members via a cam member that works together with plural units of rolling members. CONSTITUTION:When the selection switch is set at the play action position, the DC motor 32 turns the flywheel 30 in the direction of the arrow C. Thus the driving velt 96 turns the rotary members 74 and 174 of the reel mechanisms 16 and 18 toward the arrows A and B respectively. In this case, the rotary member 64 of the mechanism 16 turns toward the arrow A along with the rotary member 74 by the function of the cam member 86, and at the same time the reel hub engaging member also turns. However, the cam member 186 of the rotary member 164 of the mechanism 18 does not turn with the member 174 by the function of the cam member 186. As a result, the magnetic tape is forwarded from the mechanism 18 to the mechanism 16 in a constant speed.
