Title: Drive mechanism employing electro-mechanical transducer
Inventor: OKAMOTO YASUHIRO
IPC: H02N2/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a drive mechanism which maintains a stable friction between a drive member and a moving member coupled by friction. SOLUTION: The drive shaft 16 of the actuator 10 of a moving stage 30 is connected and fixed to one end of a piezoelectric device 17 and a slider block 18 is coupled with the drive shaft 16 b friction. The moving stage 30 is composed of a base 31, the actuator 10 provided on the base 31 and a table 34 connected to the slider block 18 with a linking member 35. As the trench parts 18b of the slider block 18 are so formed as to be point-symmetrical with respect to the axis of the driving shaft 16, a load which is applied to the slider block 18 from the table 34 through the linking member 35 is applied uniformly to the drive shaft and hence an angular moment caused by the load does not exist, friction which is newly produced between the drive shaft 16 and the slider block 18 by the load does not exist.  With this constitution, stable friction between the drive member and the moving member which is coupled with the drive member by friction can be maintained.

Title: Melting furnace
Inventor: WATANABE OSAMU
IPC: F27B3/04
Filed: 1984-03-09
Abstract: PURPOSE:To supply a prescribed amt. of molten Al without using a pump in the stage of utilizing segregation and solidification to refine Al in primary and secondary refining lines by melting the solidified Al to be supplied to the secondary refining line in a specifically constructed furnace. CONSTITUTION:Molten Al contg. impurities is segregated and solidified as high- purity Al around a rotary cooling body in plural crucibles of a primary line. Such molten Al is again melted and the Al having the higher purity is segragated and solidified around the rotary cooling body in the crucible of the secondary line by which the molten metal is refined. The Al segregated and solidified in the primary line is charged into a melting furnace 23 through an inlet 27 and is dropped by a sloped base 29 into a melting chamber 22 where the molten Al is heated to melt by a burner 30. The molten Al is admitted into a molten metal holding chamber 21 adjacent to said melting chamber. When the molten Al heated and held to and at the prescribed temp. by a burner 25 attains the level in the tap hole 24 of the chamber 21, the molten Al is made to overflow through the hole 24. The automatic supply of the molten Al by each prescribed amt. to the secondary refining line without using a pump is thus made possible.

Title: Voice/modem switching type adpcm coding system and equipment therefor
Inventor: SHIOKA MASAFUMI
IPC: H04B14/06
Filed: 1988-02-29
Abstract: PURPOSE:To reduce the hardware or software required for the changeover of voice/MODEM and to reduce the cost by transmitting a switching code to the reception side in the detection of a MODEM signal. CONSTITUTION:An input signal 110 is retarded by a predetermined time by a delay circuit 120 comprising a shift register or the like. The delay time is selected by taking the time required to detect a MODEM signal detector 130. When a MODEM signal is detected by the MODEM detector 130, an ADPCM coder 140 is switched from the voice into the MODEM application and a selector 160 is thrown to the position of 'switching code' and a code independently of the predetermined ADPCM coding is inserted to a transmission line as a switching code. Thus, the cost of the reception side is reduced.

Title: Detecting device for flowing-in of refrigerant
Inventor: SESHIMO YUTAKA
IPC: F25B49/02
Filed: 1978-04-18
Abstract: PURPOSE: To grasp the correct state of refrigerant continuously by inserting and laying a pressure sencor part into a compression member suction side refrigerant pipe in a refrigerating air-conditioning cycle.  
     CONSTITUTION: When gas-shaped refrigerant is passed through a refrigerant pipe 5, liquid-shaped refrigerant 9 is dashed to a sensor part 7 as being mixed with the gas-shaped refrigerant 8. Since the liquid refrigerant 9 has a larger mass, its impulse gives a greater shock to the sensor part 7 than the gas refrigerant 8. This force is converted into an electric signal in a pressure converter 10, and output through an integrator 11. Thus, by adding this output to a liquid compression alarm circuit, a capacity control circuit, and a discharge control circuit in a refrigerating air- conditioning cycle, the compressor can be protected, and the setting of excessive overheat degree can be unnecessary for avoiding the lowering of the appraisal index of economical efficiency.

Title: Combustion control device
Inventor: TABUSE HIROYUKI
IPC: F23N5/20
Filed: 1980-04-09
Abstract: PURPOSE: To simplify arrangement of the circuit and increase a level of safety by a device wherein the failure of ignition within a setting time is stored into a memory circuit, and hence a safety timer circuit will not be operated again until it is manually reset.  
     CONSTITUTION: A blower 1 is started upon demand for heat, and predetermined prepurge timing and subsequent ignition trial timing are set based on that starting point by using a safety timer circuit 3. As soon as only the ignition trial timing is operated by means of a relay K1 to open a pilot valve V 2 , an ignitor IG is operated. Meanwhile, when a flame detection circuit 4 detects a flame by means of a relay K2, the ignitor IG is stopped in its operation and then a main valve is opened. As a result, charging into a capacitor C7 begins from the starting point of main ignition with a comparator U1, and then discharging is started from a predetermined charged value. While the discharging is continued with a comparator U2, the relay K1 is continuously actuated.

Filed: 1986-03-05
Abstract: PURPOSE:To reduce variations in a raised temperature of each heat generating element due to variations in the number of times of driving, secure favorable printing quality and maintain a long useful life of the heat generating elements, by providing a common voltage-dividing resistor for each heating resistor group, and varying a driving voltage according the the number of times the heat generating elements in the same group are driven. CONSTITUTION:Only for a period for which a strobe pulse 33 is outputted, selection of a head-driving circuit is performed according to printing data, and heat generating resistors H1-H24 in a heat generating resistor array 20 which correspond to the printing data are energized. Of the heat generating elements in the array 20, those belonging to odd-numbered dot lines and those belonging to even-numbered dot lines are connected to a common DC power source respectively through voltage-dividing resistors 41, 42. As the number of black dots in a group of the heat generating resistors for odd-numbered or even-numbered dot lines is increased, a current passed to each of the heat generating elements is decreased, and power consumption is decreased. Accordingly, by appropriately setting the resistances of the resistors 41, 42 according to the resistances of the heat generating elements, a power source voltage and heat-releasing characteristics of a printing head, it is possible to cancel variations in a raised temperature of each of the heat generating elements due to variations in the number of print dots.
