Title: Magneto-strictive torque sensor
Inventor: NAKAMOTO AKIRA
IPC: G01L3/10
Filed: 1993-03-11
Abstract: PURPOSE:To improve the detecting sensibility of a magnetostrictive torque sensor even in the case where a magnetic aeolotropic part in a torque detecting shaft is set up to be at only one spot for composing a torque sensor. CONSTITUTION:A magnetic aeolotropic part 2 is formed at one spot on the outer periphery of a torque transmitting shaft 1, and a detecting coil 3 and an exciting coil 4 are arranged on the circumference of the magnetic aeolotropic part 2, and a torque detecting signal is obtained from the output of the detecting coil 3. A resistance 17 to fix exciting current is provided in series between the exciting coil 4 and a.c. exciting power source 5. Detecting voltage proportional to the product of the number of turns and exciting current is therefore output to the detecting coil 3. Thus the high detecting voltage can be obtained under the same exciting voltage by increasing the number of turns of the detecting coil 3, and a highly sensitive torque sensor is thereby obtained.

Title: Copying apparatus
Inventor: KIKUCHI HIDEO
IPC: G03B27/00
Filed: 1980-04-15
Abstract: PURPOSE:To assure the normality of copying operation by inhibiting automatic resetting to an initial state despite lapse of a fixed time upon ending of copying when there is a key input during warming up of a heater or the occurrence of abnormality. CONSTITUTION:A control circuit 7 executs a series of copying processes according to the information transmitted from a key input control circit 6. At the end of copying, a decision circuit 8 starts a timer circuit 9 and when the circuit 9 times up, the signal (f) is outputted, by which automatic resetting to the initial state of the ordinary copying mode in which the number of copying sheet is set at ''1'' is accomplished. On the other hand, a logic circuit 12 makes the signal (f) invalied when there is a key input during the warming up of the heater or the occurrence of abnormality and when the abnormality occurs after the key input, and makes the signal (f) effective when there is no key input within a fixed time after the completion  of said warming up or the cancellation of the abnormal state.

Title: Concrete form
Inventor: ASAMI KUNIO
IPC: E04G9/06
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent a molding face side from becoming rusty and at the same time, minimize surface contamination to mitigate an after-treatment by forming a coating layer of a transparent rust-inhibitive coating on the molding face side of a steel-made concrete form body. SOLUTION: A coating layer 2 of a transparent rust-inhibitive coating is formed on the molding face 1A side of a form body 1 of a steel-made concrete form. In this case, a highly heat-resistant lacquer coating is used which is quick- drying and easily applicable as a rust-inhibitive coating and allows wet on wet coat application, contributing to the formation of a hard and durable coat. This lacquer coating is applied a plurality of times to obtain the coating layer 2. In addition, a parting compound such as a dimethyl silicone oil is applied to the surface of the coating layer 2 according to necessity. Thus it is possible to inhibit rust to be generated on the molding face 1A side of the concrete form and at the same time, prevent an extraneous coating on the surface of a manufactured concrete product from becoming conspicuous and further, mitigate an after-treatment.

Title: Multi-step collector type electron beam tube
Inventor: KIMURA SHIYUNICHI
IPC: H01J23/033
Filed: 1978-04-27
Abstract: PURPOSE: To cool down the collector by conducting the heat occurring at plural units of collectors to the metal cylinder provided at the outer circumference the insulator component with the cylindrical insulator component provided between the collectors for support and electric insulation of the collectors used as the heat transmission line.  
     CONSTITUTION: The plate generates the heat since the electron beams are caught by voltage-applied collectors 7W10 owing to the dispersion of the velocity of the electron beams which are amplified through high-frequency circuit part 2. The generated heat is then conducted to cylindrical insulator component 12 soldered to the outer side surface of each collector and then conducted to the metal cylinder which is adhered to the outer circumference surface of component 12 to be then conducted to holding plate 6 (heat sink) via heat transmission support stage 13. Thus, the attachment of the heat sink to every collector can be omitted to simplify the structure. When the difference of the outer diameters is increased between each collector and component 12, the collector can be well insulated electrically to the earth point via component 12.

Abstract: PROBLEM TO BE SOLVED: To make the disposal after use simple and keep from increasing the waste by introducing a sheet with a specified thickness and a specific bursting strength which consists of polypropylene, polyethylene, their copolymer, or one of their mixtures and inorganic filler used against specific parts by weight of the resin. SOLUTION: As regards a resin A consisting of polypropylene, polyethylene, their copolymer, or one of their mixtures polypropylene homopolymer, ethylene- propylene copolymer, etc., may be referred to as examples. A sheet as the product should have a thickness of 0.01-1mm and a bursting strength of 0.01-5kg/cm<2> . To provide the sheet with a good push-through property an inorganic filler, consisting of talc, mica, alumina, etc., is indispensable and for this purpose it is important for the quantity of the addition of such an inorganic filler to be 5-150 pts.wt. based on 100 pts.wt. of the resin A. This constitution provides the lidding material with a good push-through property and enables simplifying the recycling after use and the disposal of the material as waste.

Title: Production of thin film and apparatus for production of the same
IPC: C23C14/24
Filed: 1992-03-10
Abstract: PURPOSE:To decrease the bumping of a molten metal and to produce the thin film free from surface defects by heating and melting a material for vapor deposition in a reducing atmosphere, thereby reducing the oxide existing in or on the material for vapor deposition to release oxygen. CONSTITUTION:A reducing gas is introduced from a reducing gas introducing pipe 31 into a space C covered with a covering wall 33 to make the space C to the reducing atmosphere. The transported front end of a supply material 22 is heated and melted by an electron beam 9B in the space C. The oxide included in the supply material 22 is reduced or cracked by the heating and the reducing gas and the oxygen is released as gas. Splashes 21b are blocked by the covering wall 33 and are prevented from arriving to the substrate even if the bumping is generated by the cracked oxygen and the splashes 21b are generated. While the molten supply material 22 is supplied by dropping the material to a region A, the vapor from the evaporating region B is deposited by evaporation on the substrate.
