Title: Printing head device
Inventor: NISHIHATA MIKIO
IPC: B41J2/255
Filed: 1993-01-11
Abstract: PURPOSE:To easily produce a printing head with a simple structure at a low cost by a method wherein printing pins are alternately arranged to be staggered in upper and low two lines and inclindedly used. CONSTITUTION:Printing pins are alternately arranged to be staggered in upper and low two lines. A printing head device is laterally inclinedly disposed so that a vertical distance between the printing pins 1 on the both ends can be coincident with a vertical height of a matrix font. When an electric current is carried to a coil 7 so as to eliminate a magnetic field of a permanent magnet 8, an armature 3 is separated from a core 6 by a resilient force of a leaf spring member 5, and the printing pin 1 flings out of a pin hole of a first front yoke 2 to print a dot by impacting a recording medium through an ink ribbon. With the interruption of the electric conduction to the coil 7, the armature 3 is again attracted to the core 6 by the magmetic force of the permanent magnet 8, and the printing pin 1 is retracted into the pin hole. By controlling the electric conduction to the two or more coils 7 in accordance with the travel position of the printing head device, a required matrix font can be printed.

Title: Distributed feedback semiconductor laser and its manufacture
Inventor: SHIBATA KIMITAKA
IPC: H01S5/00
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of the linearity of the light outputting current characteristic of a distributed feedback semiconductor laser by providing a resonator structure which generates the distributed feedback of laser light in a light guide area and changing at least the width of an active layer, the material composition of a guide layer, or the distance between the guide layer and active layer in the longitudinal direction of a resonator. SOLUTION: The n-type Inx Ga1-x Asy P1-y composition of the constituting material of a guide layer 51 constituted in a buried grating structure having a cyclic structure for generating the distributed feedback of laser light is changed in a resonator in the longitudinal direction of the resonator. Consequently, a refractive index difference occurs between the layer 51 and an upper clad layer 4 in the longitudinal direction of the resonator and, accordingly, the distribution of coupling constants also changes in the same direction.  Therefore, the deterioration of the linearity of the light output current characteristic of a distributed feedback semiconductor laser caused by an SHB (spatial hole burning in the abscissa direction) can be suppressed by changing the coupling constants in the longitudinal direction of the resonator so that the electric field distribution in the resonator may become uniform in a light guide area.

Title: Carrier balance conversion circuit
Inventor: MINEO MASAO
IPC: H03H11/18
Filed: 1992-02-05
Abstract: PURPOSE:To eliminate the need for phase correction due to application of an offset voltage or the like. CONSTITUTION:A wire pattern 80 on an IC chip is a wire pattern for signal lines through which one of bipolar signals outputted from the carrier balance conversion circuit passes to a multiplier circuit and a wire pattern 90 is a wire pattern for signal lines used to supply the other of the bipolar signals to the multiplier circuit.

Title: Tape recorder
Inventor: IWAMATSU MASAYUKI
IPC: G11B5/027
Filed: 1981-02-13
Abstract: PURPOSE:To expand a dynamic range, by dividing a signal to each plural signal level range, and recording these divided signals onto separate tracks on a magnetic tape. CONSTITUTION:An input signal is amplified by an amplifier 2, and afte that, becomes a waveform S1 whose level is below L1, by a limiter 3a, and that which is level L1 or above and -L1 or below is discarded. In this case, an output of an analog adder 3x becomes a signal which has subtracted an output of the limiter 3a from a signal S, and a signal obtained through a limiter 3b becomes a signal which has discarded signals whose level is L2 or above and -L2 or below, from a signal (S-S1). Also, an output of an analog adder 3y becomes a signal (S- S1-S2), and is obtained through a limiter 3c. These signals are recorded on separate tracks on a magnetic tape. Accordingly, the input signal is divided within a signal level range which does not reach a saturation level of the tape, and is recorded.

Title: Magnetic fluid recording device
Inventor: DAITOU CHIAKI
IPC: B41J2/01
Filed: 1981-02-12
Abstract: PURPOSE:To shorten the time to response of magnetic ink without increasing electric power in a magnetic fluid recording device by giving bias voltage that changes into two values by synchronizing with the selection signal of a stylus electrode. CONSTITUTION:A magnetic fluid recording device is provided, as in the conventional form, with a stylus electrode drive circuit 5, a control electrode drive circuit 6 and a bias voltage VB and on the bias voltage a bias circuit 7 is overlapped. The bias circuit 7 is turned ON or OFF to the timing of ON-OFF of the transistor of the stylus electrode drive circuit 5. Then VB' is set so that VB+ VB' becomes a little higher than VB. During recording, a high voltage is applied only when the magnetic ink flies. In this way the time of response of the magnetic ink is shortened. Furthermore since, during flying of the magnetic ink, the bias voltage is lowered to the voltage that is the same as before, the electric power during the flying is the same as before.

IPC: H05K3/36
Filed: 1992-02-05
Abstract: PURPOSE:To inhibit occurrence of noise by making assembly fitting easy by a method wherein wiring between a piezoelectric element of a printing unit and a head substrate is performed with an FPC. CONSTITUTION:An FPC 37 of a printing unit 20 passes through a corresponding slit 61 of a head substrate 59, and a part of its tip projects outside. Under this state, a connection part 37c of the FPC 37 is opposed to a feed path 59c in contact with the slit 61. Then, the feed path 59c is soldered to the connection part 37c. Further, under the soldered state, the FPC 37 between a piezoelectric element and the substrate is made slightly bent. Therefore, vibration generated in the printing unit 20 is difficult to be transmitted to the head substrate 59.

Title: Ic card
Inventor: HAYAZAKI MASAMI
IPC: G11C7/00
Filed: 1991-02-13
Abstract: PURPOSE:To generate a control program in source form because a translating means interprets the control program and to facilitate the development and corrections of the control program by storing a memory with the translating means which interprets the control program prescribing the operation of a microcomputer in order. CONSTITUTION:The interpreter translates the control program, stored in the ROM 12, into machine words, step by step. Consequently, the control program generated by a user in an interpreter language is executed in order. As the control program is executed, an external input/output driver 23 and a liquid crystal display element driver 22 are initialized to start operating. Thus, the control program is translated by the interpreter and executed, so the need for a program in executable form generated by an assembler is eliminated. Therefore, the development of the control program on the user side is facilitated and corrections accompanying a specification alteration are easily made.

When the rod 51 is further moved downwardly and the third valve 59 contacts with the bottom wall of the inner tube 54, the opening 54b is closed and the gas flows from the opening 54C smaller than the same 54b (the minimum flow rate).
