Title: Structure of bracket for motor
Inventor: KOBAYASHI YOSHIAKI
IPC: H02K5/08
Filed: 1986-07-02
Abstract: PURPOSE:To prevent resin form blowing to the outside circumference of a faucet section, by keeping the clearance as required between the outside circumference of the faucet section and a mold when the resin is integrally molded into a bracket. CONSTITUTION:A recessed resin inserting section 6c of a front bracket 6 is formed so as to keep a wide large clearance beta from a faucet section 6a to the outside surface of an end face section 6b where the faucet section 6a projects. On this account, if a mold 10 is put over to the outside circumference of the front bracket 6, the tip of the mold is brought into contact with the outside surface of the end face section 6b in the state where the desired clearance alpha can be kept between the mold 10 and the outside circumference of the faucet section 6a. Thus, the clearance alpha between the faucet section 6a and the mold 10 can be made in the state where the resin flow is entirely blocked, so that the resin material 9 can be prevented from flowing into the faucet section 6a.

Title: Recording and reproducing device
Inventor: NARITA SHIYUUICHI
IPC: G11B33/10
Filed: 1982-09-07
Abstract: PURPOSE:To improve both operability and reliability and to reduce the cost, by setting a standby ON/OFF stop mode in response to the pushing frequency of an existing stop switch, and displaying said stop mode by an existing display element. CONSTITUTION:When a stop switch 7 is once pushed while a magnetic tape 17 is traveling, a pulse is applied to a microcomputer 16. Then the signal delivered from an output terminal 11 stops a capstan motor 28. Therefore the traveling of the tape 17 is stopped, and a rotary drum 19 revolves thereafter to make a standby ON mode. At the same time, driving circuits 8 and 14 work to make radiate display light emitting diodes 9 and 15 of stop and still modes, respectively. When the switch 7 is pushed twice, the signals are delivered from output terminals 10 and 12 in addition to the terminal 11. Then the revolution of a head motor 23 is stopped to release the press contact of a pinch roll 20. Thus a standby OFF mode is set, and therefore only the diode 9 lights. This improves both operability and reliability.

Abstract: PURPOSE:To minimize the generation of pressure fluctuation and to reduce the generation of noises by forming the upper and lower edges of a housing in a semispherical shape, and joining tidal currents in contact with the upper and lower ends of the housing without disturbance at the rear part. CONSTITUTION:When the water stream cuased by the tidal current in the sea comes into contact with upper and lower end parts 11e and 11d of a housing 11, the stream is divided into two directions along the surfaces of the upper and lower end parts because the upper and lower end parts 11c and 11d have the semispherical shape. The streams join at the rear part without disturbance. Therefore, the disturbance of the water stream a at the rear part of the housing is suppressed to the minimum degree, and the pressure fluctuation is also suppressed to the minimum degree. Thus, the generation of noises can be minimized. When housing 11 is constituted of the cylindrical main body and the semispherical sponges, which are added to the upper edge and the lower edge of the main body, the sponges are crushed and can be housed at the time of housing. The housing assembling state is made small, and the housing property can be improved.

Title: Thick film cloth fiber coating
Inventor: KITAMURA SHIGERU
IPC: B05D7/00
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To make executable a coating uniform in the thickness of a coating film in a short time and to improve the cracking characteristic and the adhesion strength, etc., with a steel material by fixing some sheets of the cloth fibers on the shop primer coating surface of the steel material with an adhesive, etc., and applying a coating material thereon. SOLUTION: The adhesion of coating at a corner part where the coating material 4 is hardly adhered or at a curved surface part where a uniform coating film is not obtainable, is improved and the coating film having an optional thickness is obtained with the cloth fiber, and the method is suitable especially for a super thick film specification. The method is applicable when the coating material is applied to a part where deformation is large such as curved surface part of a steel structure and a place where cracking is liable to generate and the corner part, etc., where the coating film is liable to peel.  And, the method is suitable to be used at the place where the steel is brought into contact with water, sea water and chemicals and liable to etch since the coating film is hardly peeled or cracked and at the place where a maintenance after coating is difficult since the coating film is large in durability. In this way, a strength, cracking characteristic and interlayer separation performance of the coating film are improved. Moreover, the number of days and the manpower required for coating are remarkably reduced.

Abstract: PURPOSE:To prevent seizure damage of the end face of a rotor and improve reliability by a method wherein a film layer (babitt metal for example) high in the initial fitting property thereof is formed on the end face in the axial direction of the rotor, in the screw compressor accommodating the rotor. CONSTITUTION:The film layer 9 high in the initial draping property thereof is formed on the surface of the end faces in the axial directions of the rotors 2a,  2b. Said film layer 9 is formed by a substance having a small friction coefficient such as tetrafluoroethylene, a substance having a good oil lubricating property such as carbon graphite or a soft metal such as the babbitt metal, for example. According to this method, there is no fear that the seizure damage is caused on the end face 8 of the rotor even if the same 8 is contacted with the inner surface of a casing 1, and the rotor may be assembled so as to have a minimum gap between the end face 8 of the rotor and the casing 1.

Abstract: PURPOSE:To accurately measure a flow velocity and its measurement depth by provid ing a main body which serves as a weight and has a streamlined outward shape with a flow velocity pulse generating means which generates pulses corresponding to the flow velocity and a depth measuring means integrally. CONSTITUTION:A current meter 14 is provided at the tip part of the flow velocity measuring head 10 and a level gauge 24 is provided in a storage part 23 formed nearby the gravity center position of the head 10.
