Title: Roller bearing and its manufacture
Inventor: MIZOGUCHI SHINGO
IPC: F16C19/22
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To reduce the coefficient of friction of the surface of a bearing part, and to prevent generation of the seizure even when the lubricating condition is bad by forming a sulphurized layer on at least one bearing part of a bearing ring and a rolling element. SOLUTION: In a shell type needle roller bearing having a shell 1 which is an outer ring of approximately cylindrical shape, a plurality of rollers 2 in contact with an inner circumferential surface of the shell 1, and a holder 3 to hold the rollers 2, the rollers 2 are brought into direct contact with the outer circumference of a shaft 4. A sulphurized layer is formed on the surface of the outer ring 1 and the rollers 2 through the heat treatment in the atmospheric gas containing hydrogen sulfide and nitrogen, and the sulphurized layer plays a role of the solid lubrication.  Even when the outer ring 1 and the roller 2 are formed of either high carbon chromium bearing steel, case-hardened steel, carbon steel for mechanical structure, and stainless steel, the coefficient of friction of the surface can be reduced by achieving the nitrosulphurizing treatment, and the seizure is prevented from being easily generated even when the lubricating condition is bad.

IPC: B41J2/515
Filed: 1991-07-03
Abstract: PURPOSE:To enhance the responsiveness of the first impact without generating any response inferiority to the displacement on and after the second impact by judging whether the printing for the first time is performed on reference to the printing pin data of printing timing before one and adjusting head driving pulse width in response to said judgment to perform printing. CONSTITUTION:When printing operation is started, at first, a carriage is moved and, next, printing timing is taken and, in the case of OK in printing timing, it is checked whether Bit corresponding to a printing buffer is 1, that is, whether printing must be carried out. In the case of OK, it is checked whether printing is carried out in printing timing further before one and, in the case of YES, a command is issued so as to carry out printing by short pulse width on and after the second impact or voltage lower than that at the time of the first impact. In the case of NO, a command is issued so as to start printing by the long pulse width for the first impact or voltage higher than the former.

Abstract: PURPOSE:To increase the initial driving current of the motor by adding a capacitor to a circuit wherein the rotation of the DC motor is controlled reversibly by using a transistor and by utilizing a charge current flowing through the capacitor. CONSTITUTION:When a signal is inputted in an input terminal 1, a switching transistor 3 is turned on, the by transistors 5 and 6 for driving the motor are turned on to rotate the motor 11 in the fixed direction, while at the same moment the charge current flows to the capacitor 13 to increase the base current of the transistors 5 and 6 for driving the motor, and thereby the initial driving current of the motor 11 is increased. And, when the signal is inputted in an input terminal 2, the current flows to the capacitor 14 through the same operations and the motor 11 is rotated in the reverse direction by the large initial driving current. Accordingly, by adding the capacitors 13 and 14, the starting of the motor 11 can be made smooth by the charging actions thereof.

Title: Wiretapping prevention device for output cable signal
Inventor: ITO TADASHI
IPC: H04B5/00
Filed: 1994-06-22
Abstract: PURPOSE:To easily and effectively eliminate radio wave leakage and to prevent wiretapping. CONSTITUTION:An interference signal line 4 is provided in parallel to an output cable 3 where the analog signal outputted from a signal converter 5 is transmitted. The clock signal that a signal converter 5 outputs is transmitted to the interference signal line 4 via a variable resistor 42. Thus, the radio wave of the analog signal leaking from the output cable 3 and the radio wave of the interference signal leaking from the interference signal line 4 are overlapped. At this time, the intensity of the radio wave leaking from the interference signal line 4 can be adjusted to a range which eliminate the radio wave leaking from the output cable 3 completely and does not exceed the reference of a radiation interference specification by the adjustment of the variable resistor 42. As a result, the radio wave by the analog signal leaking from the output cable 3 is effectively eliminated by the radio wave of the interference signal and the decoding of the contents is made impossible at the outside of the output cable 3.

Title: Method and device for inspection of pattern of printed wiring board
Inventor: TSUKAZAKI KOUICHI
IPC: G01N21/956
Filed: 1980-11-21
Abstract: PURPOSE:To eliminate the reflected light from the flat surface of resist and inspect a wiring surface accurately by applying only the irradiation light of incident angles in a 30 deg.-40 deg. range to the wiring surface. CONSTITUTION:The light out from light sources 21 passes through lenses 22 and form rays of incident angles in a 30 deg.-40 deg. range with respect to a wiring surface 2. The incident rays of incident angles in a 30 deg.-40 deg. range reflect on the flat surface of resist and form reflected rays of reflection angles in a 30 deg.-40 deg. range. Since these angles are larger than the angle of view of a lenses 24, these rays do not enter the lens 24. The copper surface of the wiring surface 2 is polished, and the rays incident at the incident angles thereof are reflected upward on the polished copper surface and image on an image sensor 25. The optical image formed on the image sensor 25 is converted to an electric signal which is converted to a binary signal of brightness and darkness in a binary coding circuit 28, after which it is compared and collated in a pattern comparator 30.

Title: Magnetic head supporter
Inventor: SAKO KENICHI
IPC: G11B21/20
Filed: 1983-09-05
Abstract: PURPOSE:To prevent a magnetic head from shaking in the card driving direction by using a fixed member containing support parts at the front and back sides of the card driving direction and a fixed elastic matter which presses the fixed member and having a spot contact between the elastic matter and each support part of the fixed member. CONSTITUTION:A fixed member 7 fixing a magnetic head 6 contains support parts at both ends. These support parts have pins 7b which are fitted to a small hole 5a and a slit 5b and projections 7a having ball-shaped tips which have contacts with the fit points of pins 7b. A magnetic head 6 can have rotation and up-down movements since these projections 7a are pressed by a plate spring 5. Thus the head 6 can keep a close contact with a magnetic card 8 which is inserted. In addition, the head 6 is not fixed directly to an elastic matter but fixed to the member 7 and pressed by the spring 5 which is separated from the member 7 and can have up-down movements. This prevents the rotation of the head 6 in the card driving direction and ensures satisfactory record and reproduction.
