Title: Label printer
Inventor: KOYAMA SHUJI
IPC: B41J11/42
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a label printer capable of preventing occurrence of paper jamming even when a linerless label paper is used. SOLUTION: A paper sensor 9 for detecting presence or absence of a label paper L or a black mark is provided to a paper conveying passage 5 for conveying the label paper L. A pair of guide plates 6, 7 form a paper conveying passage 5. A projection 10 is provided to a portion in the vicinity of the paper sensor 9 on the guide plate 7 opposite a rear face of a printing face of the label paper L.  As a result, in the case where a linerless label paper is used, the vibration amplitude of the fluctuating label paper L is restricted by being nipped between the guide plate 6 opposite the printing face of the label paper L and projection 10 at a portion in the vicinity of the paper sensor 9 and the distance between the paper sensor 9 and label paper L is maintained roughly constant even when the gap between the guide plates 6, 7 is made wider in order to prevent the label paper L from being adhered to the guide plates 6, 7, thereby preventing an error in the sensing.

Patent JP-H0388507-A (JP)
Title: Differential amplifier circuit
Inventor: YOSHINO HIROSHI
IPC: H03F3/45
Filed: 1989-08-31
Abstract: PURPOSE:To prevent an offset voltage from being generated and to prevent characteristics from deteriorating by using a current mirror circuit as an active load circuit for an input differential couple and supplying currents which have the same value from a 2nd and a 3rd current source circuit as the input/output current of the current mirror circuit. CONSTITUTION:The output of the input differential couple 13 is amplified by a common emitter current amplifying circuit 23 and outputted from an output terminal 21. Here, the collector voltages of transistors(TR) 11 and 12 constituting the input differential couple 13 rise in potential by the base-emitter voltages of TRs 15 and 20. Therefore, the collector potentials of the TRs 11 and 12 are as high as each other and the offset voltage which is generated owing to imbalance between the collector potentials becomes extremely small. When constant current sources 18 and 19 are composed of TRs, the value of the collector-emitter saturated voltage VCE sat is much smaller than the VBE of the TRs, so even when a source voltage VCC is lowered to almost 1V, sufficient operation is realized.

Title: Rotation detector
Inventor: FUKUZAWA YOSHINAO
IPC: G01D5/245
Filed: 1988-09-08
Abstract: PURPOSE:To obtain a rotation detector to efficiently detect rotation by using a superconductive member to constitute the detecting winding of a rotation detecting part. CONSTITUTION:A detecting part winding 4c provided in a rotation detecting part 4 and a transformer winding 5c provided in a rotation transformer part 5 are together made of a superconductive wire consisting of a superconductive material. A signal is transmitted to and received from a detecting part winding part 4c of a detecting rotor 4a of the rotation detecting part 4 through the rotation transformer part 5, and the obtained rotation detection signal is taken out to the external through the rotation transformer part 5. At the time of detecting operation, the copper loss due to the resistance for flow of a current is eliminated and heating is considerably reduced because the winding 4c is made of superconductive wires. The rotation detection characteristic of the rotation detecting part 4 is considerably improved because the temperature is not raised by the copper loss, and the phase deviation f the rotation detection signal is minimized because of no resistance of the winding 4c. Further, conversion is very efficiently performed because the superconductive wire is used as the transformer winding 5c.

IPC: G11C11/41
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To transmit and write a correct data in a cell while eliminating erroneous operation even for a high speed chip by combining a peri-top address transition detection signal with a peri-bottom address transition detection signal to have a constant pulse width without being controlled by the pulse width of both detection signals thereby producing an address transition detection signal. SOLUTION: A peri-top address transition detection signal and a peri-bottom address transition detection signal are NANDed by an NAND gate NAND 21 and delayed at a delay circuit section DE and then passed through an NAND gate NAND 22 to produce an address transition detection signal ATDSH. The address transition detection signal ATDSH has a constant pulse width dependent on the delay rate at the delay circuit section DE. Since the enable point of a write control signal WC can be quickened, a correct data can be transmitted to a cell and written therein even for a high speed chip.

IPC: H04N5/937
Filed: 1987-09-08
Abstract: PURPOSE:To prevent skew distortion without using a 0.5-H delay line by counting reproduced horizontal synchronizing signals in signal period to modify the vertical directional address in a digital memory, and counting signals in horizontal frequency generated by a PLL during a noise period also to modify the vertical address. CONSTITUTION:The PLL21 is composed of a VCO22, a saw tooth wave generation circuit 23, a sample holding circuit 24, a phase compensating circuit 26, a switching circuit 27, and a capacitor 29 for holding. Also, the PLL21 generates a signal in a horizontal frequency synchronized with a reproduced horizontal synchronizing signal. During a signal period, the vertical directional address in the digital memory is modified by counting reproduced horizontal synchronizing signals, but in a noise period, sad modification of address is achieved by counting said signals in horizontal frequency. As a result, skew distortion can be corrected by controlling the vertical directional address in the memory without using any delay line.
