IPC: G03B17/24
Filed: 1994-05-19
Abstract: PURPOSE:To provide a camera which enables either an autoprint or non-correct print mode to be set at good controllability as required. CONSTITUTION:A means for setting a print mode detects a print mode setting switch SW3 (S102), then assigns -1=autoprint or -1=non-correct print to a print mode setting flag FP (S103, S104), and assigns the flag FP to a print information flag F (S105). A variation means detects a print mode setting changing switch SW4 (S107) after the SW1 is turned on, and changes the print information flag F to -F (S108) if the switch SW4 is on, and causes it to be displayed on a display device (S109). Before a release SW2 is turned on, the print information flag F is cyclically inverted each time the SW4 is turned on by loops among S106-S110. After releasing (S111), the value of the flag F is magnetically recorded (S113) during film advancing, and the flag F is restored to the value of FP (S114).

Title: Manufacture of shape memory material
Inventor: KAIEDA YOSHIYA
IPC: C22F1/10
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To improve mechanical properties such as strength, ductility and fatigue life by applying the hydrostatic treatment to a shape memory material after performing the heat treatment for the shape memory. SOLUTION: The pressure to be applied to the shape memory material during the hydrostatic treatment is preferably the value at which the mechanical properties of the material are improved to a maximum. Though the mechanical properties of the material are improved proportional to the magnitude of the pressure, the effect of the pressure becomes not remarkable at the prescribed pressure compared with the previous effect. Thus, the pressure can be specified, for example, up to the yield stress of the shape memory material. The temperature during the hydrostatic treatment is preferably <= the temperature range where the shape memory material shows the shape memory performance.  Because the yield stress of the material becomes smaller as the temperature is lower in the above-mentioned temperature range, it is more favorable as the environmental temperature during the hydrostatic treatment is lower, but when the temperature is too low, the pressurizing medium is solidified or it becomes costly to drop the temperature, and the room temperature is preferable in a practical condition, and from the safety aspect.

Title: Permanent magnet rotor
Inventor: KOIKE YOSHIKAZU
IPC: H02K29/00
Filed: 1990-05-18
Abstract: PURPOSE:To improve magnetic balance so as to improve the generating characteristic of an electric motor by providing flowing easiness of magnetic flux different between the magnetic fluxes flowing in a rotor iron core and a magnetic pole piece. CONSTITUTION:A rotor iron core 1 consists of soft iron or high silicon steel such as a magnetic material of high relative magnetic permeability. A magnetic pole piece 3 is constituted of magnetic material of low relative magnetic permeability to consist of nickel or the like. Accordingly, in a magnetic pole where repulsive force is generated in the rotor core by same poles (S pole) of permanent magnets, a magnetic path is generated long but a magnetic material is provided with high relative permeability, so that magnetic flux density can be increased by allowing magnetic flux to easily flow. In a magnetic pole(N pole) generated in the magnetic pole piece, a magnetic path is generated short, but flux density can be decreased because of low relative magnetic permeability. Accordingly, magnetic balance between the rotor core and the magnetic pole piece can be attained.

Filed: 1980-09-17
Abstract: PURPOSE: To achieve high speed and high accuracy in hybrid luster scan type apparatus by sensing the moving speed or position of a table, and variably controlling the deflecting direction and deflecting position of an electron beam based on sensed data.  
     CONSTITUTION: The table 31 sequentially repeats the movement (L) in the Y direction and the step movement (l) in the X direction by a table moving device 32. The entire region of a specimen 10 placed on the table is exposed. A computing device 36 counts, computes, and measures the moving speed and position of the table 31 from the signal of a laser interferometer 34. Based on the measured value and the describing data inputted from a computer 37, the position, the direction, and the speed of the deflection scanning of the electron beam is computed. An electron beam deflecting device 38 is driven and the beam scanning is controlled by said computed results, and highly accurate describing is performed even at the accelerating and decelerating time of the table 31 without inclination in the exposing direction and position errors. Since unavailable time is eliminated in the high speed movement of the table 31, the high speed is substantially achieved.

Title: Optical inverter circuit
Inventor: YANASE TOMOO
IPC: H01L27/15
Filed: 1988-05-25
Abstract: PURPOSE:To obtain an optical inverter circuit with which information can be exchanged optically by a method wherein a common layer is used as the emitter layer of a phototransistor and the anode layer of an LED, and the base absorbing layer and the collector layer of the phototransistor and the light emitting layer and the anode layer of the LED are isolated from each other by element isolation. CONSTITUTION:If a light input X exceeding the threshold level of a phototransistor(TR) 25 is inputted to the TR 25, the TR 25 is in a conducting state. Then a current applied to a resistor 28 is increased and a voltage applied to the anode of an LED 26 is declined. If the resistance of the resistor 28 is so selected as to have the declined voltage lower than the threshold voltage of the LED 26, the LED 26 does not emit a light when the TR 25 is in the conducting state. If the light input is lower than the threshold level of the TR 25, the TR 25 is in a cut-off state and the current applied to the resistor 28 is decreased. Therefore, the anode side voltage of the LED 26 is elevated and the LED 26 emits a light when the elevated voltage exceeds the rising voltage of the LED 26. With this constitution, a light output whose state is opposite to the state of a light input can be obtained. If an N-P-N transistor 27 is employed as a phototransistor, the same function can be obtained.

Title: Cryogenic cooler
Inventor: KAMEI KEIJI
IPC: F25B9/00
Filed: 1989-05-24
Abstract: PURPOSE:To reduce the transmission of a vibration to a material to be cooled by deflecting a diaphragm by pressure chamber due to the slide of a displacer, circulating working fluid to transfer heat, and employing a flexible tube as the part of a circulation passage. CONSTITUTION:When pressure in a cooling chamber 35 is raised as a displacer 33 is moved to the side of a top dead center A, a diaphragm 37 is deflected to a pump chamber 39 side since it has flexibility. Since the pressure in the chamber 39 becomes high, a reverse flow preventive valve 55 is closed, cooled working fluid is fed in a flexible tube 53, and introduced into a head chamber 49. Then, as the displacer 33 is moved to a bottom dead center B side, the pressure in the chamber 35 is lowered, and the diaphragm 37 is deflected to the chamber 35 side. Accordingly, since the pressure in the chamber 39 is lowered, a reverse flow preventive valve 57 is closed, the fluid raised at its temperature is fed into a flexible tube 51, and returned into the chamber 39. Thus, transmission of vibration to a material to be cooled can be reduced.
