Title: Production of engine valve
Inventor: MORI KAZUHIKO
IPC: C21D9/00
Filed: 1989-03-17
Abstract: PURPOSE:To produce an engine valve having excellent wear resistance by forming an alloyed layer consisting of Cr, C and Fe and having a specified composition on the valve face of a heat-resistant steel valve main body with high-density heating energy and then applying specified heat treatment. CONSTITUTION:The alloying material powder contg. Cr and C is arranged on the valve face 2 of the valve main body 1 made of a martensitic heat- resistant steel. High-density heating energy such as laser light is then impressed on the powder to rapidly melt the alloying material along with the lower valve main body base material layer. The materials are alloyed, and an alloyed layer 3 contg., by weight, 20-50% Cr, 1-3% C and the balance essentially Fe is formed. The alloyed layer 3 is then heated at 400-700 deg.C for 5min to 5hr, and then quenched by water, etc. Consequently, the structure of the alloyed layer 3, in which a eutectic carbide is crystallized in the matrix consisting essentially of hard martensite, is formed. By this method, an engine valve having the valve face 2 consisting of the alloyed layer 3 having excellent wear resistance is obtained at a low cost.

IPC: B26B19/28
Filed: 1990-03-14
Abstract: PURPOSE:To inform to a user a fact that necessity for charge comes by displaying and informing to a user as to charging at the time of non-use, and also, displaying immediately a fact that a rotating speed of a motor by a motor rotating speed control means is switched from a controllable state to an uncontrollable state in the course of use. CONSTITUTION:While a light emission diode 20 of a control displaying part 23 is turned on in green, even if a fluctuation of a load occurs, a motor is always maintained at a prescribed rotating speed by a motor rotating speed control means, and shaving can be continued. When the light emission diode 20 is switched from green to red and turned on, it is warned that the rotating speed of the motor 6 by the motor rotating speed control means is becoming uncontrollable already against a fluctuation of a load. In this state, even if the light emission diode 20 is turned on in red, in the case of a usual use form, shaving of a once portion can still be continued. However, use of the next time is impossible in most cases, and when the light emission diode 20 comes not to emit light, urgent necessity for charge for preparing completely for use of the next time is warned to a user.

Title: Parallel error counter circuit
Inventor: SUDA YUKIO
IPC: H04L1/00
Filed: 1988-03-18
Abstract: PURPOSE:To save number of IC basic logic gates by applying one side error count means for the count of an error bit generating singly and counting the error bit generating simultaneously by a simultaneous error count means and counting the total error by logic calculation. CONSTITUTION:If an error bit takes place only at one side, an output of an OR circuit 50 changes to L and a one-side error counter 10a is counted. When the input of the OR circuit 60 changes to L simultaneously, the simultaneous error counter circuit 20a makes count. Then in order to count each state of the one-side error counter circuit 10a and the simultaneous error counter circuit 20a as the total error bit number for the output NANDing them by NAND circuits 30(1)-30(8), the NAND circuit 31 NANDs the result. Thus, the IC basic logic gates required to constitute the parallel error counter circuit based on ring counters in this way are nearly a half the IC basic logic gate number based on shift registers.

Filed: 1988-03-18
Abstract: PURPOSE:To prevent damage and sound by on-off actions and to maintain good linearity in a wide frequency range by using two semiconductor switches which are partly commonly connected to selectively connect a horizontal linearity correction coil to a horizontal deflecting yoke. CONSTITUTION:A photocoupler 5 turns off and FETs 4A, 4B turn off to prevent the correction coil 2B from acting when a transistor 7 is turned off by inputting an 'L' to the base terminal SC of said TR while the linearity of the horizontal scanning frequency of a personal computer connected to a display monitor is obtainable by using only the correction coil 2A. The TR 7, the coupler 5 and the FETs 4A, 4B are turned off by applying an 'H' to the terminal SC to connect both the coils in parallel and to make correction in the case of using the coils 2A, 2B. The FETs 4A, 4B and diodes 9A, 9B are selected between the capacity 3 horizontal deflecting yokes so that deflection current flows. The damage by the selection of the correction coils and the noise by the selection operation are thus eliminated.
