Also, when the ball case 5 is formed by connecting two half bodies, a plurality of spherical insertion shells 10 are formed, and one metallic ball 8 is inserted having a clearance 9 in each insertion shell 10. Then, when the piping 1 is vibrated, the ball 8 generates vibration of play due to collision in the insertion shells 10 and generates impulsive force. Therefore, the vibration energy of the piping 1 is converted into shock energy, and the vibration energy of the piping 1 is seemingly reduced, so that the vibration of the piping 1 can be suppressed.

Title: Electrophotographic copying method
Inventor: YUGE SHIZUO
IPC: G03G15/22
Filed: 1979-11-16
Abstract: PURPOSE: To prevent a white omission phenomenon at a high-density part by performing high-density development by applying a bias voltage of a magnetic brush processor in the high humidity environment with a transfer type electrophotographic copier that uses a high resistance magnetic toner.  
     CONSTITUTION: Conductive developing sleeve 7 of processor 6 is normally connected to earth terminal (a), but connected to terminal (b) of bias power source 10 to apply a bias when humidity is high. In such a constitution, the bias voltage is applied to the magnetic brush processor when the humidity is high to perform high- density development, so that a white omission phenomenon at a high-density part  can be prevented. When the humidity is extremely high, the electrostatic latent  image potential is decreased before the development and the bias voltage is applied  to magnetic brush processor 6, so that even when the humidity is very high, an  excellent copy is obtained.

Title: Round tooth tool
Inventor: KUBOTA SEIICHI
IPC: B26D1/24
Filed: 1988-06-17
Abstract: PURPOSE:To narrow the width of a thin knife peripheral surface that comes into contact with a cut material and improve the extent of sharpness as well as to simplify the repolishing by fitting a thin knife in an annular recess of a holder installed in a shaft, while installing an elastic member which presses this knife toward the opposite knife. CONSTITUTION:A knife N1 is formed annularly with a plate of 0.1mm-0.4mm in thickness, and a holder 1b, forming an annular recess 1a at the peripheral side of a shaft S1, is installed on this shaft S1. The knife N1 is fitted in this annular recess 1a, and this knife N1 is pressed to another knife N2 at the opposite side by an elastic member 2. Thus, since plate thickness of the knife N1 is 0.1mm-0.4mm, even if a flank is not formed on the circumference, width of a peripheral surface N1b of the knife N1 that comes into contact with a sheetlike cut material becomes narrowed, and thereby its sharpness is made so better. Moreover, even at time of repolishing the knife N1, it is merely enough to polish the peripheral surface n1b alone, so that repolishing becomes simplified.

Title: Clutch disk
Inventor: KONO SATOSHI
IPC: F16D13/64
Filed: 1988-06-17
Abstract: PURPOSE:To stably transfer a power by rotatably externally fitting an outer hub provided with a recessed part engaging with a gap in a rotating direction into an external protrusion formed on the outer periphery of an inner hub connected to an output shaft, elastically connecting both the hubs through a spring member and forming curing layers on external opposite surfaces of both the hubs. CONSTITUTION:At the time of connecting a clutch, an inner hub 21 and an outer hub 22 are relatively rotated by a prescribed angle, and then, the outer protrusion 21a of the inner hub 21 abuts against the engaging recessed part 22a of the outer hub 22 to stop the relative rotation of the inner hub 21 and the outer hub 22. Then, a rotating force is transferred from the outer hub 22 to the inner hub 21 through the engaging part. At that time, the rotating force is converged to the engaging part of the inner hub 21 and the outer hub 22, however, since a curing layer is formed on at least one of the externally opposite surfaces of the inner hub 21 and the outer hub 22 and an abrasion resistance is improved, a power is stably transferred for a long period.

Title: Head lamp change-over circuit
Inventor: ISHIKAWA KIMIAKI
IPC: B60Q1/02
Filed: 1980-10-25
Abstract: PURPOSE:To enable eyes of a driver to be adapted to change of distributed light in a front head lamp having a main lamp and sublamp changed over by supplying to the main lamp pulse current which receives the output a control voltage generating circuit to narrow its pulse width gradually after the change-over. CONSTITUTION:A sublamp SL is lit by changing over a dimmer switch DS to the sublamp side. At the same time, current IML flows in a main lamp ML correspondingly to the switching condition of a switching circuit SC which switches the current in a certan cycle. Continuity time in that one cycle is approximiately in proportional to the output voltage of a control voltage generating circuit SG. Also, input terminal 1 of the circuit SG is earthed by changing over the dimmer switch DS to vary change-over detecting to voltage into L. Thus, the output voltage is gradually lowered. When it becomes lower than a reference value, the switching circuit SC becomes nonconductive so that the main lamp ML is completely turned off.

Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To positively prevent the variation of the characteristics of an MOSFET by preventing fluoric ions or sodium ions from mixing in a channel region. SOLUTION: Fluoric ions or sodium ions never enter a nitride film 20 because the film structure of the nitride film 20 interposed between a gate electrode 22 and a gate oxide film 18 is dense. Accordingly, even if implanting energy of fluoric ions which is implanted into a gate electrode 22 is too high, for example, the fluoric ions never penetrate the nitride film 20 and enter the channel region. Sodium ions never penetrate the nitride film 20 and enter the channel region in the manufacturing process or under the using conditions thereafter.
