    摘要: A semiconductor test circuit includes an input terminal, a controller, a setting circuit, a command generator, a transmission path switching circuit and a comparator. The input terminal receives a serial data including a command code and a control data. The controller receives a control signal and outputs an internal control signal based on the control signal. The setting circuit receives the serial data and outputs it in response to the internal control signal. The command generator generates an interface signal based on the serial data received from the setting circuit. The switching circuit has ports, receives the signal from one of the ports and outputs the received signal to another one of the ports in response to the internal control signal and the command code. The comparator compares the interface signal received from the command generator with the signal received from the switching circuit.

    摘要: A fluid circuit module controls a fluid to be supplied to a movable element in an automatic transmission. The fluid circuit module is provided with a first body in which a first flow passage is formed, a second body in which a second flow passage is formed. A separation plate is set between the first body and the second body and has a deformation portion that is deformed and strained in accordance with the difference between pressures in the first flow passage and the second flow passage. A strain sensor is attached to the deformation portion for detecting a strain of the deformation portion. A control means controls a supply fluid to be supplied to the movable element on the basis of a detection result of the strain sensor.

    摘要: An electrically programmable and erasable non-volatile semiconductor memory such as a flash memory is designed into a configuration in which, when a cutoff of the power supply occurs in the course of a write or erase operation carried out on a memory cell employed in the non-volatile semiconductor memory, the operation currently being executed is discontinued and a write-back operation is carried out to change a threshold voltage of the memory cell in the reversed direction. In addition, the configuration also allows the number of charge-pump stages in an internal power-supply configuration to be changed in accordance with the level of a power-supply voltage so as to make the write-back operation correctly executable. As a result, no memory cells are put in deplete state even in the event of a power-supply cutoff in the course of a write or erase operation.

    摘要: A cam mechanism for a lens barrel includes an annular member which is linearly guided along an optical axis, and having a cam follower on an outer peripheral surface; a cam ring having a cam groove on an inner peripheral surface including a photographing section and an accommodation section, the cam follower being engaged in the cam groove; and a biasing device for biasing the annular member forward to normally press the cam follower against a front cam surface in the cam groove. A rear end portion of the cam groove is open at a rear end surface of the cam ring to serve as the accommodation section, and the cam follower is disengageable from the front cam surface in the cam groove against a biasing force of the biasing device when the cam follower is engaged in the accommodation section.

    摘要: A semiconductor device having a first circuit block supplied with a first operating voltage, a second circuit block supplied with a second operating voltage, a voltage generating circuit for generating a third operating voltage in response to the first operating voltage, and a third circuit block supplied with the third operating voltage. Preferably, the third operating voltage is generated such that the first operating voltage is increased to a fourth operating voltage by a voltage-up converter, and then the fourth operating voltage is dropped to the third operating voltage by a voltage down-converter. Hence, a power supply operating internally stably in spite of use of a relatively fluctuating voltage can be provided even in the case where a power-supply voltage is dropped.

    摘要: A semiconductor IC device is designed using a memory core with a plurality of I/O lines, a transfer circuit module and a logic library which are produced beforehand and stored in a data base. The memory core and a logic circuit are arranged so that their I/O lines extend in the same direction. A transfer circuit including plural stages of switch groups is arranged between the I/O lines of the memory core and the I/O lines of the logic circuit. Switches forming each stage of switch group are formed between the I/O lines of the memory core and the I/O lines of the logic circuit. When one stage of or a small number of stages of switch groups are turned on, the I/O lines of the memory core and the I/O lines of the logic circuit are turned on, thereby forming a desired transfer pattern. The memory core is constructed by the combination of functional modules such as an amplifier module, a bank module and a power supply module. In the bank module are arranged row-system circuits which operate independently of each other and a multiplicity of I/O lines which extend in a bit line direction.
