Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To raise the transmission rate by detecting the error conditions of video signals and controlling audio signal output by the error of the detected result. SOLUTION: Packet data are spread and modulated by using spreading codes in the spread spectrum transmission circuit 106 of a slave unit 101, modulated to RF signals and radio-transmitted to the spread spectrum reception circuit 108 of a master unit 107. The digital audio data of the one-field unit of the output of the circuit 108 are written to an audio signal rate buffer 111 by the write control signals of the output of a memory controller 112. Read digital audio data from the buffer 111 are inputted to an output control circuit 114, and when it is judged that digital video data corresponding to the audio data are damaged in an error detection correction circuit 109, it is judged that a damage is also generated in the audio data. In this case, the circuit 114 controls the output to a speaker 115 of the audio data so as to hold or mute the audio data by normal data. The need of addition data for error detection and correction for audio signals are eliminated.

Title: Semiconductor device threshold voltage setting method
Inventor: AOKI HIROSHI
IPC: H01L29/78
Filed: 1990-10-31
Abstract: PURPOSE:To stabilize transistor features and improve yield by making the substrate impurity concentration and implantation dose dependence on gate film capacity almost equivalent. CONSTITUTION:In order to achieve the target threshold value Vt. a certain dosage (Ni) of an impurity with an opposite polarity to the substrate polarity is ion implanted in the substrate near the boundary with a gate oxide film. The amount of change ( Vt) in the threshold voltage Vt caused by this implantation is also dependent on the gate film capacity Cox constant and varies with the gate oxide film thickness tox. At this time, by setting the relationship between the impurity concentration Na and the dosage Ni to be equivalent to the gate film capacity Cox constant, since the Vt change is the opposite of the variation of the gate oxide film thickness tox variation, a Vt' higher than Vt and the  Vt change cancel out and the threshold value Vt remains constant unaffected by variations in the gate oxide film thickness tox.

Title: Air bag control device
Inventor: TAKAHASHI TOSHINORI
IPC: B60R21/16
Filed: 1994-10-31
Abstract: PURPOSE: To enable judgment even with the generation of such deceleration as to cause the speed change value to reach the threshold value in a short time due to impact such as a hammer blow acting upon the vicinity of an ECU without making the start judgment of an inflator for the specified time after the first change value becomes positive. CONSTITUTION: When the first speed change value V1 does not reach the threshold value TH4 even after operation carried out for the fixed time or longer in order to avoid actuation caused by the offset voltage of an acceleration sensor, it is so judged that deceleration is not caused by a collision, and judgment operation is reset (steps 130-136). With this action, when the time after the first speed change value V1 becoming positive, that is, the operation elapsed time (t), does not reach at least 6ms, an actuation judgment is not made. Accordingly, even when the speed change value V2 reaches the threshold YH2 due to large deceleration generated in a short time by impact such as a hammer blow applied close to an ECU, an air bag device is not actuated, so that the quality can be improved (steps 146-160).

Title: Liquid fuel combustion device
Inventor: ARAI YASUHIRO
IPC: F23D11/40
Filed: 1989-11-10
Abstract: PURPOSE:To improve combustion rate and achieve low noise by providing a fuel nozzle in a vaporizer, forming a primary air nozzle, encircling said nozzle, on the axis thereof, and forming the blow-off diameter of the nozzle into a variable one. CONSTITUTION:During high-load combustion, a large quantity of liquid fuel is forced into a vaporizer 2 through a fuel nozzle 3, while primary air from an air feed system 8 is blown thereinto through a primary air nozzle 4. Since the nozzle 4 has a variable diameter 6, a large diameter is automatically provided to achieve atomization of fuel. A heater 11 is heated to raise temperature in the vaporizer 2, so that the fuel is vaporized and blown off from a burner port 12 in the form of flames. A flame holding ring 13 is provided around the port 12 to stabilize the flames and recover combustion heat, whereby the vaporizer 2 is heated to minimize power consumption of the heater 11. During low-load combustion, the fuel feed rate is decreased, the air feed rate from the system 8 is reduced and the diameter 6 is made smaller to gain optimum static pressure and promote combustion efficiency. During high-load operation, the blow diameter 5 of the nozzle 4 is caused to increase as the air rate increases, preventing thereby the static pressure from rising abnormally high, resulting in avoiding generation of noise.
