In this case, the base material 10 is not decarburized because the layer 11 is present and the formation of a decarburized layer is prevented. Therefore, the coating 12 is formed on the base material 10 densely and uniformly as well as adherent force thereof can be made high and crack or peeling of the  coating can be prevented in a cooling process after the coating 12 is formed. In addition, the intermediate layer 12 can be formed from titanium nitride according to  chemical vapor deposition.

IPC: G03G15/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To lower the moment of inertia at a stopping time, shorten the time until coming to a constant velocity rotational motion state, even if the moment of inertia at a rated rotation is the same, and miniaturize a motor or the like for making its weight light as well as reduce in cost. SOLUTION: A container 10 has a hollow disk-like shape, is mounted on a rotation axis which is perpendicular to a machine for rotating around the rotation axis. Inside the container 10, several spherical bodies 12 are stored. The spherical bodies 12 not being affected by force other than gravity, they position at random in the container 10, when flywheel is stopped. However, when the container 10 rotates around the rotation axis, a centrifugal force is added, then the spherical bodies 12 move circumferentially for being arranged annularly along the inner surface of a circumferential wall 10a of the container 10. Thereby, the flywheel will have a larger moment of inertia at a rated rotation than that at a stopping.

IPC: H04B10/00
Filed: 1986-05-26
Abstract: PURPOSE:To switch an optical-fiber transmission line to a new line for switching without interrupting a communicating state, by directly producing by working light branching and coupling devices to the currently used line and controlling the optical signal level by making the branching ratio variable. CONSTITUTION:Light branching and coupling devices 21a and 21b are directly produced by working at a job site by stress-cutting the optical fiber of a currently used line 10 without producing any axial shifting and inserting probes 22a and 22b for branching into spaces between end faces while the intervals between the end faces are finely adjusted and, at the same time, the optical signal level is controlled by making the branching ratio variable. Therefore, the level change of optical signals is controlled during the working process of the currently used line 10 and switching process to this switching line 14 and the AGC function of the transmitter side can sufficiently be utilized. Regarding the delayed time difference of the optical signals caused by the line lengths before and after switching, synchronism can be maintained to an optional transmitting speed, by temporarily converting the optical signals into electric signals by using a temporary switching line 13 and utilizing the variable delayer 32 of an electric system.

Title: Semiconductor device
Inventor: SHIROTA SHOZO
IPC: H01L21/60
Filed: 1987-05-15
Abstract: PURPOSE:To prevent device outage by a method wherein a well opposite to the substrate in the type of conductivity is formed, corresponding to a bonding pad, in a semiconductor substrate. CONSTITUTION:A semiconductor substrate 1 is kept at OV when it is of the P type and a well 6 therein is of the N type. Accordingly, even in the presence of a leak between an aluminum bonding pad 4 and the well 6 due to performance-degrading cracks or the like in a field oxide film 2 or in an insulating layer 3, there will be no current flow. It is because a voltage of only 0-5V will be supplied to the well 6 and this results in a reverse direction voltage application. The semiconductor substrate 1 is kept at 5V when it is of the N type and the well 6 is of the P type. Even in the presence of a leak between the pad 4 and well 6 due to cracks in the field oxide film 2 or in the insulating layer 3, there will be no current flow. It is because a voltage of only 0-5V will be supplied to the well 6 and the N-P junction between the semiconductor substrate 1 and the well 6 will be exposed to a reverse direction voltage only. This design prevents a semiconductor device from defective performance or outage.

Filed: 1979-09-19
Abstract: PURPOSE: To make execution of a program loop high-speed, by giving a loop structure to the instruction buffer group as a ring counter and by closing the loop of the instruction buffer group when the program is detected.  
     CONSTITUTION: In case that the branch instruction enters into buffer B and it is forecasted that branch conditions are satisfied in the branch condition deciding circuit, loop deciding circuit 4 is set.

When the branch instruction reaches the last instruction buffer, it is decided by branch deciding circuit 20 whether branch conditions are satisfied or not. As long as it is decided that branch conditions are satisfied, loops of the instruction buffer group and the operand address register group are continued.
