Title: Thermal printer
Inventor: FUJII IWAO
IPC: B41J11/00
Filed: 1986-09-25
Abstract: PURPOSE:To prevent the tension and slack of a recording paper and reduce the load of a CPU, by a method wherein all platens are simultaneously driven at the time when all thermal head complete one-line printing is detected and one-line printing start signals are issued to the respective thermal heads. CONSTITUTION:With one-line printing start signals outputted from a control circuit 8, driver circuits for every head block start printing and a printing completion signal to be outputted to the control circuit 8 is made to fall, whereby each of thermal heads conduct printing. With the completion of one-line printing, printing completion signals per head are made to rise. After the rising of all the signals per head, a logic circuit 7 turns to high level. The control circuit 8 makes a platen motor drive signal rise to drive motors 16, 26, and 36 for a period of the time corresponding to one line and thereby the drive signal is made to fall to output printing start signals. In this manner, all the thermal heads are simultaneously driven when all the thermal heads complete printing, which eliminates the possibility of the occurrence of tension and slack in a recording paper. Moreover, the load of a CPU in the control circuit is reduced because the situation is entirely the same as in the case where the CPU in the control circuit controls any one thermal head and one platen.

Abstract: PURPOSE:To attain changeover without interrupting the communication by sending reception synchronization information of an original radio equipment in communication in a base station to a destination radio equipment of a new channel, and synchronizing in a timing represented in the synchronization information. CONSTITUTION:When it is judged that the changeover of a radio channel is required and a changeover destination radio channel is decided, a parameter of reception synchronization stored in a bit/frame synchronizing circuit of an original radio equipment 19 is outputted to a control section 21. Then the control section 21 informs the parameter to a bit/frame synchronizing circuit of a changeover destination radio equipment 20. The original changeover radio channel in communication at present designates the changeover destination radio channel to a mobile station 17 and the mobile station 17 uses an idle time slot to changeover the radio channel. The bit/frame synchronizing circuit of the radio equipment 20 applies decoding and starts the reception in a timing of a clock recovered from the parameter of the bit/frame synchronizing circuit of the radio equipment 19 via the control section 21. Finally the original changeover radio channel is released. The mobile station 17 makes communication with the radio equipment 20 without interrupting the communication with the radio equipment 19.

Title: On-column conductivity detector for electrokinetic separation by microcolumn
Inventor: ZARE RICHARD N
IPC: G01N15/10
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To detect chemical species with a high sensitivity by providing an on-column type conductivity electrode having a leading end part which extends to a column channel penetrating a side face part of a small-diameter cylindrical column and terminates in the same plane at a column inner wall, and an effective electrokinetic potential-impressing means passing a separation zone along the column channel. SOLUTION: A silica glass capillary tube is filled with a conductive liquid. When a potential is impressed to electrodes at both end parts of the capillary tube, a cation chemical species 18 is attracted to a cathode 16 and an anion chemical species 19 is turned back by the cathode 16. Since a velocity of the liquid is higher than an electrophoretic velocity of the chemical species 18, 19, all chemical species move at different velocities and measured between electrodes 21 and 22 when passing a detector consisting of the electrodes 21, 22. A conduction characteristic having a background depending on a difference to a sample is accordingly changed. The electrodes 21, 22 are on-column type. An inner diameter of a microcolumn is smaller than 500 μm, and the microcolumn is formed of an inactive metal, e.g. platinum or the like.

Filed: 1986-09-29
Abstract: PURPOSE:To obtain a microphone amplifier circuit for a camera incorporated type VTR while eliminating undesired sound by providing a differential amplifier circuit receiving the output signal of the 1st and 2nd audio amplifier circuits and amplifying the difference of both the input signals. CONSTITUTION:When the operator applies zooming, the position of a slider of a multi-rotation type variable resistor 17 is turned to the upper limit and the resistance is increased and the control voltage at a terminal (a) of a changeover switch 19 is increased. Thus, the gain of the voltage controlled amplifier 14 is increased and the output signal level of the amplifier circuit 13 is boosted. In this case, the output voltage V2 of the voltage controlled amplifier 14 is fed to the noninverting input of the differential amplifier circuit 31 and the output voltage V1 of the amplifier 3 is fed to the inverting input. Thus, the circuit 31 operates the difference between the voltages V2 and V1 as Vout=(R2/ R1).(V2-V1), where R1 is a resistance of resistor 32 and R2 is a resistance of resistor 33. The output voltage Vout is a signal cancelled with the noise component only and an object is closed up and the surrounding noise is excluded more as the screen is narrowed.

Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a disc brake having a friction pad which can be pressed to a disc by calipers with an always uniform contacting pressure to reduce eccentric wear, etc., generated in the friction pad. SOLUTION: Among mounting parts 18 and 19, provided on calipers 14, the mounting part 18 positioned on the inlet side about the rotating direction A is formed longer in a rotating direction A than the part 19 positioned on the outlet side. The cylinder part 16 is thus installed eccentrically toward the outlet in the rotating direction A. The mounting part 18 is furnished with built-up parts d1 and d2 arranged in the longitudinal direction, and thereby the thickness in axial direction of a disc 11 is made thicker than that of the mounting part 19. In braking operation, when a bending moment in the direction of Arrow M applies on the calipers 14, the bending rigidity of the mounting part 18 against this bending moment is made greater than that of the mounting part 19.
