Abstract: PURPOSE:To allow the control of steering power without impairing reliability, even when a steering power control motor is driven and controlled using two arithmetic units having different performance. CONSTITUTION:This control device is equipped with a main CPU 100 and a sub-CPU 101 respectively operating and outputting drive and control information on a motor 4 to control force for operating a steering wheel, as well as performing fault diagnosis for each other and the device itself on the basis of the operation result, and a motor drive circuit 107 for outputting a drive signal to the motor 4 on the basis of the drive and control information from both CPUs 100 and 101. Furthermore, each of the CPUs 100 and 101 has a transmission and receiving means for sending and receiving the signal of the fault diagnosis result to and from each other, and a signal interruption means for shutting out drive and control signal from the operating section of either CPU 100 or CPU 101, when the fault of either of the CPUs 100 and 101 is identified from the received diagnosis result.

Title: Ultrasonic diagnostic apparatus
Inventor: OGASAWARA TATSUO
IPC: A61B8/00
Filed: 1990-02-06
Abstract: PURPOSE:To obtain a uniform ultrasonic image without uneven brightness with a correction of sensitivity of each ultrasonic raster to be constant by measuring an intensity of a received echo signal for each ultrasonic raster to control an amplification factor of the received echo signal according to the results of the measurement. CONSTITUTION:An echo signal C received with a probe 4 from an object to be inspected is an echo signal within an acoustic lens 19 and it is obtained as each ultrasonic raster is generated. An intensity of the signal is measured by sampling it at a timing of a sampling pulse D for AGC with an AGC controller 1. An AGC voltage F corresponding to the results of the measurement is outputted. The voltage F is added to an STC voltage G with an adder 2 and applied to an amplifier 14 as AGC-STC voltage H. The amplifier 14 is so controlled that an amplification factor of the echo signal reduced for each ultrasonic raster to be outputted from a long amplifier 13 according to a level of the voltage H when the voltage H is large and it increases when the voltage H is small. The output echo signal of the amplifier 14 is applied to a monitor 17 through a detector 15 and a DSC 16 to be displayed as ultrasonic image.

Title: Heat exchanger
Inventor: TAKITANI KOICHI
IPC: F28F1/40
Filed: 1988-02-05
Abstract: PURPOSE:To prevent the occurrence of the unstable flow of fluid to be heated and to improve heat transfer efficiency, by a method wherein a heat transfer promoting body to increase incurring of a pressure loss is inserted in a preheat area in a heat transfer pipe, and a heat transfer promoter to decrease a pressure loss to a value lower than that of a preheat area is inserted from a nuclear boiling area to an superheat area in a state to be connected to the aforesaid heat transfer pipe. CONSTITUTION:Water entering a heat transfer pipe 1 flows an annular passage, having a narrow flow area, formed between the heat transfer pipe and the outer peripheral surface of a solid round rod 34 situated in a preheat area. The mass velocity in a pipe of water is increased, a pressure loss is increased to promote heat transfer of a heat transfer surface. Water is heat-exchanged with liquid sodium to increase temperature, and flows an annular passage 39 in a preheat area. The water flows a helical flow passage 40 between the heat transfer pipe and a twist tape 36 located in a range of from a nuclear boiling area to a superheat area, a mass velocity in the pipe is decreased, and an increase in a pressure loss is decreased. Thus, the nuclear boiling area having a high heat transfer rate is lengthened, a film boiling area having a low heat transfer rate is shortened, and a heat transfer rate is improved. Further, since a pressure loss in a range of from the nuclear boiling area to the superheat area is decreased and a pressure loss in a preheat area is increased, the generation of an unstable flow in the heat transfer pipe 1 can be prevented.

Title: Manufacture of recording medium master disk, and recording medium
Inventor: MASUHARA SHIN
IPC: G11B7/00
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To prevent a synchronizing signal from being distored by first optical beams by exposing only the portion corresponding to grooves by second optical beams and wobbling the second light beams in accordance with the synchronizing signals when exposing the area where the synchronizing signal is recorded. SOLUTION: A fin clock mark 6 for generating the clock to control a disk revolving speed is recorded on an optical disk as address information. The mark 6 is formed by weaving a first side wall 4a of a groove 4 by the first optical beams and a second side wall 4b of the grove 4 by the second optical beams. In the area where the mark 6 is recorded, other address signals are formed larger than an amplitude t2 of the weaving formed on the recorded wall 4a. Thus, even through the amplitude amount of the clock mark 6 is equal to that of the conventional fine clock mark, the amplitude of the reproduced signal correspond to the marks 6 is made larger.

Title: Automatic stopping circuit of tape recorder
Inventor: TAMAI RIYUUJI
IPC: G11B15/093
Filed: 1982-02-19
Abstract: PURPOSE:To stop a tape recorder automatically, by turning off its power source when a transistor (TR) which detects potential variation of a capacitor charged or discharged according to the rotation of a reel shaft, performs inverting operation, or when the power supply voltage is higher than a prescribed voltage. CONSTITUTION:According to the rotation of a reel shaft 1, contacts 2 and 3 are short-circuited intermittently and the capacitor (C) 10 is charged and discharged alternately. On detecting variation in the potential of the C1 attending the rotation stop of the shaft 1 the TR6 for detection is turned on. Once an overvoltage is applied to a power source line 6, a bias voltage is applied to a control TR23 through a TR15 for power supply and the emitter and base of a TR16 for power souce control to turn on the TR23. Therefore, the emitter power voltage of the TR6 drops and the TR16 is turned on. Further, a TR15 is turned off through the TRs 12 and 16 to cut off power supply to an electric circuit 14. Thus, a detection part is prevented from malfunctioning and the supply of an overvoltage is inhibited to stop the tape recorder automatically.
