Title: Scanning stylus of pickup
Inventor: KUDOU TOSHIYUKI
IPC: G11B9/07
Filed: 1982-07-26
Abstract: PURPOSE:To prevent the reproduced output characteristic of a scanning stylus from an actual influence due to a virtual electrode before the scanning stylus reaches its mechanical limitation in a video disc player, by molding the 1st projection part to remove electrode metal dispersed and adhered to the lower end part of the 1st side of a base material and also molding the 2nd projection part to guide the scanning stylus to a grinding groove easily. CONSTITUTION:Since the 1st and 2nd projection parts 4, 6 are molded after fitting the electrode metal on the surface 8 of the scanning side, the dispersed metal adhered to the periphery of the scanning surface 7 is removed at the time of said molding. The electrode metal is not adhered to the 2nd and 3rd sides 42, 62. Since the 5th ridgeline 44 is arranged on the upper part of the 2nd shoulder part 61 in the 2nd side 42, the 1st side 25 is not adjacent to the scanning surface 7 even at the arrival of the life of the scanning stylus to be abrased by the 2nd projection part 6, so that significant electrode action is not generated even if the dispersed metal exists on the 1st side 25.

Title: Amplifier type load converter
Inventor: YOSHIDA TAKAO
IPC: G01G3/12
Filed: 1983-07-20
Abstract: PURPOSE:To facilitate maintenance and make it possible to reduce the total cost to a large extent, by forming a strain yielding part, whose cross sectional area is made smaller than other parts, and facing strain transmitting parts, amplifying and transmitting the strain, and using an inexpensive material. CONSTITUTION:A strain yielding part 4, whose cross sectional area is smaller than the other parts, is formed in the intermediate part between a load applying part 2 and a mounting table part 3. The outer parts of the slits 6 and 7 are split and strain transmitting parts 8 and 9 are formed so as to face each other. Strain detectors 10 are fixed to the transmitting parts. The strain, which is yielded in the strain yielding part 4, is amplified and transmitted to the strain detectors 10 through the transmitting parts 8 and 9. Thus the converter, whose sensitivity is 5-10 times that of the conventional load converter, can be obtained. Therefore, an inexpensive material, whose strength is low in the range wherein the load and the strain are proportional, can be used. At the time of failure, only the detector 10 can be replaced, and the total cost can be reduced to a large extent.

Title: Reducing method of contact resistance
Inventor: TAINO NOBUYASU
IPC: H01L21/768
Filed: 1981-08-20
Abstract: PURPOSE:To reduce contact resistance as well as obtain an ohmic contact, by implanting impurity ions in the vicinity of the contact area between a high- melting metal and Si through the high-melting metal. CONSTITUTION:An SiO2 film 3 is opened on an N-layer 2 of an Si substrate 1, and an Mo film 5 is deposited thereon by the CVD method. After P ions are implanted through the Mo film 5, a heat treatment is applied thereto at about 900 deg.C. Thereby, the resistance between the N-layer 2 and the Mo is remarkably reduced, and there is no possibility that the contact resistance value rises or the contact changes to a nonohmic contact thereafter. Accordingly, heat treatment can be applied even after making the contact. In other words, the thus obtained ohmic contact can advantageously cope with various manufacturing processes of the device.

Abstract: PROBLEM TO BE SOLVED: To suppress the deformation or cracking frequently occurring at the time of drying and improve the productivity by supporting lower ends of both lateral faces of a tile body with a receiving tool, bringing warm air shielding pieces into contact with both the lateral faces and feeding the warm air from the perpendicular direction relatively to the lateral faces. SOLUTION: A receiving tool 20 is a platy form and the top surface of the receiving tool 20 is composed as a horizontal plane so that the lower ends of the lateral faces of a tile body W can horizontally be supported. A pair of warm air shielding pieces 30 are stood in the longitudinal direction on the top surface of the receiving tool 20 with a kept interval corresponding to the width of the tile body W. The warm air shielding pieces 30 are capable of suppressing the feed of warm air in a drying furnace when placing the tile body W on the receiving tool 20. The warm air shielding pieces 30 are capable of suppressing the deformation of the tile body W due to the own weight in addition to the shielding of the warm air.  Furthermore, a warm air regulating piece 40 integral with the receiving tool 20 is installed under the tile body W placed on the receiving tool 20 to weakly regulate the flow of the warm air fed to the back surface side of the tile body W.

Title: Inverter
Inventor: TSUCHIYA AKIRA
IPC: G05F1/44
Filed: 1978-10-25
Abstract: PURPOSE: To prevent the saturation of an inverter transformer and raise its reliability, by using a differential current transformer to detect an exciting current due to the saturation of the core of the inverter transformer and turning off an inverter.  
     CONSTITUTION: DC power is applied to the primary side of an in erter transformer  1 while the polarity of the DC power is changed over. An exciting current due to the saturation of the core of the inverter transformer 1 is detected by a differential current transformer 6 and rectified by a rectification circuit 7. The rectified current is converted into a voltage by a resistor 8. The voltage is compared with a reference voltage 10 by a comparator 9. The reference voltage 10 corresponds to the value of the exciting current at the maximum level of magnetic flux density. When the value detected by the differential current transformer 6 exceeds a reference value, the output of the comparator 9 is inverted and the turn-off angle of a gate drive circuit is controlled so that an inverter 4 is turned off. This results in preventing the saturation of the core of the inverter transformer and improving its reliability.

Abstract: PROBLEM TO BE SOLVED: To precisely display a track data such as link on a map by correcting the geometric coordinate value of a track data to be stored as occasion demands. SOLUTION: Whether the position of a link stored in a RAM is within a prescribed range or not is judged (step SQ3).

Filed: 1978-10-27
Abstract: PURPOSE: To improve electric properties of semiconductor elements through removal of residual material of a photosensitive resin, a low temperature gas plasma treatment is performed after electrodes have been formed by lift off method using the photosensitive resin.  
     CONSTITUTION: The oxide layer 11 on top of impurity-diffusioned silicon wafer 10 is coated with a photosensitive resin 12, and selective etching process is used to form an electrode window in the surface. Then, an evaporated aluminum film 15 is deposited and heated in an innert gas to permit the photosensitive resin 12 to be decomposed to carbonaceous material. An adhesive tape is used to remove unwanted aluminum, leaving a formed electrode 16. The procedures allow insufficiently decomposed substances 17 of the photosensitive resin to remain on the substrate, which is then removed by the use of a low temperature gas plasma treatment. In this manner, the process can provide the semiconductor element with an enhanced electric properties, production yield, and reliability.
