Title: Method for cleaning liquid toner
Inventor: ARIKAWA AKIRA
IPC: G03G21/00
Filed: 1991-08-21
Abstract: PURPOSE:To prevent the problem of color mixture caused by the defective cleaning of a developing electrode rotating body from occurring by impressing a voltage whose polarity is reverse to the polarity of liquid toner on a liquid toner cleaning means. CONSTITUTION:In order to enhance a cleaning effect, a bias whose polarity is reverse to the toner is impressed on electrical conductive blades 13a-13c. In such a case, the positive voltage is impressed, for example. Since the polarity of the bias impressed on the developing electrode rotating body 12 is reverse to the polarity of the bias impressed on a cleaning blade 9, it is good that the impressing timing is sequentially controlled. That means, when the polarity of the liquid toner is negative, the bias is impressed on the rotating body 12 to have the negative polarity. Next, when the liquid toner attached on the rotating body 12 is eliminated, the voltage impressed on the rotating body 12 is turned off and the polarity of the voltage impressed on the blade 9 is made positive. Then, the liquid toner is sucked by the blade 9. Such operation is repeatedly executed in the case of multicolor copying.

Title: Drive circuit for stepping motor
Inventor: OOBA RIYOUZOU
IPC: H02P8/14
Filed: 1983-12-12
Abstract: PURPOSE:To increase the torque at the high speed time by superposing and supplying overvoltages in the prescribed time width at every pulse at the high speed time. CONSTITUTION:When a slowup signal is outputted, the output of a gate 9 becomes a H level, a transistor TR3 is turned ON, and transistors TR1, TR2 are turned ON. Thus, the potentials of points Va, Vb become VDDH. N pulses are set as the operation pulse in advance at slowup time, and whether the N pulses are driven or not is checked whenever the phase is switched. While the N pulses are driven, an overvoltage is supplied to a coil 6, driven by a high torque, and when the drive of the N pulses is finished, the slowup signal output becomes OFF, and the Pa output becomes H level. At this time, the output state of a gate 9 is controlled by the output of a monostable multivibrator 11, and since the overvoltage VDDH is applied, the torque is increased.

Title: Refrigerant blow-off sound preventing structure of capillary tube
Inventor: KURIHARA AKIO
IPC: F25B41/06
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent an occurrence of a refrigerant blow-off sound by forming an enlarged tube portion at a connecting end of a capillary tube connected with an evaporator. SOLUTION: A capillary tube 10 is made of a copper alloy tube material and has its front end formed in an enlarged tube portion 10a. The capillary tube 10 has its proximal end connected with a liquid receiver. At a connecting portion where the capillary tube 10 and an inlet connecting tube 4 of an evaporator are connected with each other, a liquefied refrigerant which flows through the capillary tube 10 passes through the enlarged tube portion 10a of the capillary tube 10 and is blown off from a distal end opening 11 thereof toward an inside of an enlarged diameter portion 4b of the inlet connecting tube 4.  With such a blow-off operation, since the blow-off velocity and blow-off pressure of the refrigerant from the distal end opening 11 of the capillary tube 10 can be reduced compared to those of conventional capillary tubes, the occurrence of the refrigerant blow-off sound can be prevented.

Title: Gas dissolving device and shower device using the same
Inventor: YOSHIDA HIROAKI
IPC: A47K3/28
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent carbon dioxide from being discharged into a bathroom from a shower unit. SOLUTION: Gas which is not dissolved by an ejector 14 is separated by a gas and liquid separating means 19. Therefore, gas is not permitted flow from a water flow-out port 22 so that the supply gas density of a place for supplying water where gas is dissolved is prevented from being increased. Moreover, gas which is not dissolved is separated by the gas and liquid separating means 19 so as to be supplied again to a gas supply tube 16 with a gas circulating passage 23 and gas is circulated till it is dissolved. Thus, dissolved gas is not uselessly used and is effectively utilized at almost 100% level.

IPC: G01L3/10
Filed: 1986-10-03
Abstract: PURPOSE:To obtain a high-accuracy torque sensor by using a cut type member for one of two discoid rotary drums and putting their magnetic recording parts close to each other. CONSTITUTION:The rotary drums 3 and 3' are formed in cut shapes which have shaft fitting parts 2 and 2', and their magnetic recording parts 4 and 4' are put close to each other to a fine interval Ls.

Title: Originating system for private exchange
Inventor: KIKUCHI HITOSHI
IPC: H04Q3/62
Filed: 1983-12-13
Abstract: PURPOSE:To attain the assured transmission of dial tones to an office exchange by transmitting the 1st digit by a transmission key for connection to a trunk line when the transmission of the digit is expected to the trunk line from a private exchange and then transmitting the 2nd and following dial numbers with the second push of the transmission key after confirming the dial tones of the office exchange. CONSTITUTION:A control circuit 4 receives the signal from a dial key 8 and then reads out a dial number from a storage circuit 5. When the first digit of the number is discriminated, an access number is read out of an access number memory 9 for office exchange and compared with the first digit. When the coincidence is obtained from this comparison, only the first digit is sent to a dial transmission circuit 1. The circuit 1 receives the dial number and then sends the first digit to the office exchange. Therefore the dial tones are transmitted to the corresponding telephone from the office exchange in response to the transmission of the first digit. These dial tones can be can be confirmed through a talking circuit 2. Thus the originating subscriber pushes the key 8 again, and this dial number is sent to the office exchange.

Abstract: PROBLEM TO BE SOLVED: To allow a conveying truck to smoothly move on a deck plate formed with unevenness by arranging ball casters, formed by holding steel balls rotatably, at specified spaces at the lower face of a base of the conveying truck. SOLUTION: A conveying truck 1 is provided with wheels 4 arranged longitudinally and laterally at the lower face of a base 2 of plate shape, and moved by pushing a rising/falling handle 3.

When the conveying truck 1 transfers to an adjacent deck plate 6, transfer is smoothed by a taper face of a guide member 5 of trapezoidal cross section provided at the front end of the base 2.  The conveying truck 1 can therefore move smoothly on the deck plate formed with unevenness.
