Title: Thermocouple for measuring molten metal temperature
Inventor: SHIINA HARUO
IPC: B22D17/22
Filed: 1994-04-21
Abstract: PURPOSE:To provide a thermocouple for measuring molten metal temperature with faster response. CONSTITUTION:A thermocouple C is manufactured in order to measure the temperature of molten metal injected into a mold 15. The thermocouple C is provided with a heat resistant electrical resistor 2 whose one end face 10 is in contact with a molten metal M and a pair of wires 3 and 4 whose one end parts are exposed at the one end face 10 by penetrating them in the insulator 2 respectively. The molten metal M is used for a high-temperature joint part between the one end parts in the wires 3 and 4. Thus, when the molten metal M reaches the one end parts of the wires 3 and 4 of the thermocouple C, the temperature of the molten metal M can be measured quickly and accurately by the thermocouple C.

Title: Method for electron beam exposure and apparatus used in said method
Inventor: FURUKAWA YASUO
IPC: H01L21/027
Filed: 1980-06-18
Abstract: PURPOSE:To control the amount of exposure without changing the conditions of an electron gun, by applying a high frequency voltage on an electron beam deflection device, vibrating the electron beam at a right angle, passing the beam through a screening plate having an opening, and controlling the pulse width of the pulse shaped beam. CONSTITUTION:The high frequency voltage is applied on the reflecting plates 11 of the electron beam exposing apparatus, and the high frequency alternating field is formed. The electron beam 2 is deflected by the electric field and vibrate as shown by an arrow 16. The electron beam 2 passes through a screening plate 14 when the beam moves from A to B. When the electron beam exceeds B, it is screened by the screening plate 14, and is not sent out. This state continues until the  beam moves from B to C and B again. The electron beam passes the opening 17 when it moves from B to A and to D. The beam is not sent out when it moves from D to E and D again. In this method, the electron beam is transformed into a pulse shaped beam, and the amount of exposure can be readily and precisely controlled without changing the conditions of the electron gun.

Abstract: PURPOSE:To make parallel processing of data storing operation in a memory from the outside and accessing operation from a processor to the memory possible, by providing a circuit which retreats the processor in accordance with a control signal from the outside when both the operations concur with each other. CONSTITUTION:When data writing in a memory RAM is performed from an ex- ternal device EXT, the output of a terminal EACT is ''L''. If a processor MPU accesses the memory RAM under this condition, the output of the output terminal RDYD of a clock generator CG is supplied to the waiting terminal RDY of the processor MPU so as to cause the processor MPU to wait until a writing signal terminal WR becomes ''L'' and the terminal EACT becomes ''H''. This data processor is set in such a way that, when the processor MPU starts accessing of the memory RAM just before a terminal SACT becomes ''L'', a data enable terminal DE goes to ''L'' and the writing is terminated before a data storing operation in the memory RAM from the external device EXT is completed.

Title: Power failure monitor device and system
Inventor: MURAKAMI HIDEYUKI
IPC: H02J13/00
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To attain the easy application even of a system where the number of signal lines is physically limited or the installation is difficult for an exclusive cable itself by detecting a power failure to a monitoring object device based on the signal level of a time division signal specifying position given from the monitoring object device. SOLUTION: If the supply of power is cut to a device B, the supply of power is also cut to a power monitoring part 14 and a serial bus in interface 15 contained in the device B. Thus, the part 14 and the interface 15 cannot actively operate and the potential of a serial bus cable 16 becomes deficient. A serial bus interface 13 of a device A, i.e., a monitoring main body device is designed based on fail-safe and accordingly the signal of monitoring information corresponding to such as unsteady state is raised to an H level. Thus, the monitoring information which are given to a power supply cut detection part 11 from a power monitoring part 12 are consecutively set at H levels. As a result, a power supply cut state of the device B is detected.

IPC: B60K23/04
Filed: 1980-06-20
Abstract: PURPOSE: To improve the steering operation by simplifying the change operation to differential-lock front and rear wheels or only the front wheel or others.  
     CONSTITUTION: In a normal state, since front and rear wheel differential lock pedals 46 and 47 are not stepped on, front and rear wheels on the right and left are  respectively and independently driven for rotation. When slipping bigins, when the  front and rear wheel differential lock pedal 47 is stepped on, a wire 52 and a rod 54  are pulled together, and front and rear wheel differential lock gear mechanism 11  and 27 are together changed into the state of differential lock, consequently preventing the slipping. When the front wheel differential lock pedal 46 is stepped on for  turning a machine body, the wire 52 is pulled, and only the front wheel differential  lock gear mechanism 11 is brought into the differential lock state. Then, the front  wheel is prevented against alipping, and the turning operation of the machine body  can be sufficiently assisted by rear wheels driven for rotation independently to each  other.
