Title: Rotary magnetic head device
Inventor: OZAKI SHINJI
IPC: G11B5/02
Filed: 1988-01-22
Abstract: PURPOSE:To eliminate a transmission line, to obtain a suitability for a wideband signal transmission and, simultaneously, to cause an assembling work to be very easy by causing the conductive layer of a fixed transformer and the conductive layer of a substrate to be in contact by means of a pressing member engaged with a fixed cylinder. CONSTITUTION:A conductive layer 20 with a prescribed winding is provided on a fixed transformer 5 of a rotary magnetic head, and a second conductive layer 21 is provided on a substrate 1 to which the amplifier circuit of reproducing signals from magnetic heads 1a and 1b is mounted. The conductive layers 20 and 21 are made in contact through an elastic member 22 by a pressing member 23 engaged with a fixed cylinder 6, and an electric conduction is executed. Consequently, since the reproducing signals are impressed to the reproduction amplifier circuit in a head device, the transmission line can be widely shortened, a stray capacitance can be decreased, the suitability for the wideband signal transmission can be obtained, and simultaneously, since only the pressing is executed and a soldering is not executed, the assembly can be made very easy.

Title: Information transmitting method
Inventor: FURUKI HITOSHI
IPC: G06F11/30
Filed: 1982-01-29
Abstract: PURPOSE:To reduce the load of a computer to realize a high-processability information transmitting device, by dividing the data cycle from a remote supervisory and controlling device (master station) to a low cycle and a high cycle by the normal state and the urgent state to realize a high-efficiency transmission adapted to the computer processing. CONSTITUTION:In figure, the cycle of input data is 4 seconds (low cycle), and the processing time required for it is 100msec. At an emergency such as an accident, the input cycle is shorter and is changed to 2 seconds (high cycle). Here, power system data is taken as an example to explain this cycle. continous occurrence of emergencies is not considered because the emergency occurs once or less in a day; and if data of a breaker CB and a protection relay RY exist in the analysis of the accident, the cycle is shortened in two cycles because they can be analyzed. When the accident occurs under these conditions, the calculated load of the computer is about 2.7%. Consequently, the load of the computer is reduced to the approximate half.

Title: Electronically-controlled fuel injector
Inventor: MORI AKIRA
IPC: F02D41/14
Filed: 1984-01-25
Abstract: PURPOSE:To reduce a shock, by providing a means for changing the speed of the return from OTP control to normal control, depending on the condition of an engine, to prevent its torque from being sharply altered. CONSTITUTION:An electronically-controlled fuel injector is put under normal control in which a theoretical air-fuel ratio is used as an aimed value, or under OTP control which is performed to set the ratio of fuel to air at a larger value than the theoretical value. In a step S1, it is judged whether or not an OTP control condition is in the range of the execution of the OTP control. When said condition has sharply and greatly gone out of the range, a step 5 is taken to make an OTP increment value FOTP zero to stop the OTP control and perform based on a basic fuel injection quantity. When the OTP control condition has slowly gone out of said range little by little, the OTP increment value FOTP is diminished (steps S7, S8) to gradually shift the fuel injector from the OTP control to the normal control. The torque of an engine is thus prevented from being sharply altered, to reduce a shock.
