Title: Brushless motor drive circuit
Inventor: NAKASUJI TOSHIAKI
IPC: H02P6/14
Filed: 1981-08-26
Abstract: PURPOSE:To form a drive circuit a brushless motor drive circuit which can suppress the offset voltage to small value capable of being ignored by providing a low pass filter in a feedback circuit of a DC amplifier system for amplifying  the output of a rotor rotating position detecting magnetoelectric transducer. CONSTITUTION:A rotating position detection signal of a rotor from a Hall element 1 is amplified through an operational amplifier 3 and a single-ended push- pull power amplifier 5, and is applied to an exciting coil 7 of a brushless motor. A low pass filter 12 is provided in the feedback circuit of a DC amplifier system 10 which has the amplifiers 3, 5, and the relation of R2+R3=R5 is set to suppress the offset current of the amplifier 3 to low value. Since the feedback  amount is reduced as the rotating speed of the rotor is increased due to the  provision of the low pass filter 12, the gain of the system 10 increases proportionally to the rotating speed, and the offset voltage can be suppressed by the  automatic removing function of the circuit itself by selecting the value of R5/R1  to small value.

Title: Recording head and driving method for the same
Inventor: TAMURA YASUYUKI
IPC: B41J2/345
Filed: 1986-06-11
Abstract: PURPOSE:To prevent an adverse effect due to a voltage drop and uniformize thermal application with a thermal element array by constituting a structure in such a way that a common electrode is connected to the adjoining end of an adjacent thermal element and applying a different voltage level to an electrode on both ends of a thermal element to be heated according to image information. CONSTITUTION:If a signal LHLHHHLH(L represents 'low level' and H 'high level') is input to an input terminal of electrodes D1-D8, an output of the electrodes D1-D8 which have passed through a driving means 3 becomes LHHLHLLH. Consequently the voltage level at both ends of thermal elements S1, S3, S7 corresponding to the electrodes D1, D3, D7 to which L signal is input becomes the same, since the electrode D0 is at low level. At the same time, the voltage level at both ends of the thermal elements S2, S4, S5, S6, S8 corresponding to the electrodes D2, D4, D5, D6, D8 to which H signal is input, becomes different. Thus only the thermal elements corresponding to the H signal are energized and heated to perform an image recording in thermal transfer recording according to image informations.

Title: Centralized lubricating device
Inventor: HIROSE YUICHI
IPC: F16N7/38
Filed: 1991-06-05
Abstract: PURPOSE:To enable the supply of lubricant corresponding to the actual operating time. CONSTITUTION:When a power switch 13 is turned on, a pulse generation count part 11a counts the pulse-number of a pulse signal from a generator by a counter. The accumulated value of the pulse-number counted by the pulse generation count part 11a and the count-number set value are stored in a non-volatile memory 20, and an accumulated value update part 11b updates the content of the accumulated value stored in the non-volatile memory 20. A lubricating action command part 11c outputs an oil feeding command signal in the case of the accumulated value after updating becoming a count-number set value. A controller 12 turns a switch 18 on in response to the oil feeding command signal so as to drive a pump 16, and thus lubricant is supplied to each vehicle bearing 14. The supply of lubricant corresponding to the actual operating time can be thereby performed by storing the accumulated value into the non-volatile memory 20.

Abstract: PURPOSE:To realize an operation through the single power source and then increase the using factor of the voltage as well as ensure a free change for the inclination of the output waveform, by securing a combination between the current Miller circuit and the constant current generating circuit which applies the current corresponding to the control voltage. CONSTITUTION:A common connection is secured between the bases of the transistor TR8 and TR1 having a connection between the base and the collector, and the control power source 5 is connected to the collector of the TR8 via the resistance 3. Then the emitters of the TRs 1 and 8 are connected to the power source 6. Thus the current Miller circuit is formed. And the source 5 is formed with the DC voltage generating means corresponding to the parameter of the temperature, the rotational frequency and the like of the engine. Then the parallel circuit of the capacitor 2 and the swicth 4 is connected to the collector of the TR1, and thus the saw-tooth wave is delivered through the terminal 7 of the parallel circuit. Thus the function of the TR1 is continued until the collector potential reaches nearly the Vcc and regardless of the source 5. As a result, the using factor can be increased for the voltage, at the same time securing the operation via the one power source 6.

In the condition the pressure contact is completed, the conductor of the electric wire contacts the conductor pressure contact part 4 to achieve electrical connection. At the same time, wire caulking bosses 3', 3' at the tail of the terminal 1 break through the insulation sheet 6 and protrudes at the sides of the electric wire 7, and caulking is made in such a way that the electric wire 7 is embraced so as to fix together the electric wire 7 and the insulation sheet 6 situated below it. This yields a condition where the pressure contact part 4 is reinforced to prevent generation of defective connection.

Title: Joint gasket
Inventor: YATO YUKINORI
IPC: E04B1/684
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To improve workability and a waterproofing property by extending a connection wall near a center across the internal sides of both side walls of a long-sized joint gasket having an approximately U-shaped cross section. SOLUTION: A connection wall 2 is extended near the internal center of both side walls 1a of a joint gasket 1 and projection straps 4 are formed on the internal sides of both side walls 1a near the open end of the gasket 1. A pressure-sensitive adhesive tape 5 with mold releasing paper is affixed to the external sides of the side walls 1a. Then, when a joint X between molded plates A is waterstopped, the bottom wall 1b of the gasket 1 is kept in contact with the joint X, and a flat plate type jig 10 is inserted in the open end of the gasket 1 for pressing the wall 2, thereby pushing the gasket 1 to the prescribed depth of the joint X. In this case, the wall 2 pulls the walls 1a inward. As a result, resistance against insertion is lessened, and the peeling off of the tape 5 or the like is prevented. Then, the releasing paper is peeled and the jig 10 is vibrated, thereby bonding the tape 5 to the walls of the joint X. Thereafter, the joint X is filled with an amorphous sealing material. According to this construction, a work can be easily executed and a proper waterstopping property can be ensured.
