Title: Platen holding device of printer
Inventor: MAKINO KOUSHIN
IPC: B41J11/14
Filed: 1984-07-10
Abstract: PURPOSE:To arrange so that no missing of printed characters may occur without fail by suporting a platen with a support resisting paper friction and maintaining a fixed gap between the platen and a printing head. CONSTITUTION:If a latching solenoid 10 is excited at a start printing signal, a plunger 10a is released from a permanent magnet and an actuator 19 is pulled upward by spring 23. In the meantime, a platen 15 is pushed upward by spring 9 and then is positioned by stopper 22 thus deciding a gap G between the platen 15 and a printing head 1. On the other hand, a release lever 28, interlocked to the actuator 19, parks from a support 26 centering around a supporting shaft 27, and the support 26 rotates counter-clockwise. Then this support contacts a stopper 30, braces the opposite part of the platen 15 and prevents paper 12 from separating from a printing head 1 by friction. Accordingly, if printing action is resumed right after the feeding of the paper 12, no missing of printed characters occurs, because the gap G is maintained correctly.

Abstract: PROBLEM TO BE SOLVED: To provide a medium recording technology recording programs ranging over plural recording mediums and its reproducing technology. SOLUTION: This device reproduces concerned programs from plural recording mediums in which programs having branching structures related to plural file blocks are recorded separately so that file blocks of one or move them two blocks can be reproduced following the reproducing of one file block. At this time, in a first recording medium A, when file blocks (n-2∼n) equivalent to the last of the banching structure are reproduced, file information specifying the concerned file blocks are stored and when a second recording medium B is reproduced following the first recording medium, the reproducing of the concerned second recording medium B is started by selecting file blocks (N+k-2∼n+k) corresponding to the file information.

Title: Flame detector
Inventor: YAMAGUCHI TETSUO
IPC: G01J1/02
Filed: 1987-06-10
Abstract: PURPOSE:To obtain a flame detector which is reliable for a long period by projecting the tip part of an optical fiber slightly from an optical fiber head. CONSTITUTION:An optical waveguide 1 is fitted to the dedicated seat of a burner assembly and three fibers 3, 4, and 5 are installed on the optical fiber head in 0 deg., 15 deg., and 30 deg. visual field angles. A concentration nozzle 11 is provided in front of a ceramic cover 9 so as to prevent dust of combustion gas from sticking on the photodetection surfaces of the fibers 3, 4, and 5. Further, cooling air 12 is divided by an air distribution sleeve 8 into primary cooling air 13 which flows in the gap 18 formed outside the cover 9 and secondary cooling air 14 which flows on the side of the internal surface 22 of the cover 9 to cool respective parts, and injected into a furnace through a nozzle slit 19. Then the photodetection parts of the fibers 3, 4, and 5 are projected from the head 2 by about >=2mm, and then even if the cooling air stays at the end surface part of the head 2, the photodetection surfaces of the fibers 3, 4, and 5 are not at the air staying part and the sticking of particulate dust is eliminated.

Title: Lighting fixture for vehicle
Inventor: IWATA CHIHARU
IPC: F21Y101/00
Filed: 1995-06-09
Abstract: PURPOSE: To obtain the prevention of leakage light and airtightness between mutual plural lighting fixtures (an illuminating lamp and a signal lamp). CONSTITUTION: Two partition walls 10A and 10B are arranged in a lamp housing 1 by leaving an interval between them, and recessed parts 20A and 20B into which the tips of the two partition walls 10A and 10B are inserted are arranged on a lens 2. Packing 5 is sandwiched between the tip of the partition wall 10B and a surface of the recessed part 20B, and this packing 5 is pressed against the surface of the recessed part 20B by an elastic connecting part 11 arranged in tip parts of the two partition walls 10A and 10B. As a result, since an interval exists between the tips of the two partition walls 10A and 10B inserted into the recessed parts 20A and 20B of the lens 2, the leakage light between mutual illuminating lamp A and signal lamp B is prevented by this interval.  Airtightness between the mutual illuminating lamp A and signal lamp B is held by the packing sandwiched between the tip of the partition wall 10B and the surface of the recessed part 20B.

Title: Vertical synchronization detecting circuit
Inventor: KITAZAWA KEIO
IPC: H04N5/10
Filed: 1979-11-07
Abstract: PURPOSE:To improve vertical synchronization tection performance, by comparing the pattern, which is obtained by slicing the video signal by a prescribed level and subjecting it to serial-parallel conversion, with the storage pattern corresponding to the regular vertical synchronizing signal. CONSTITUTION:Output pulses obtained by slicing the TV video signal input in multilevel circuit 4 by a prescribed level are taken into shift register 6 at every fixed timing and are converted to parallel data. The address of ROM7 is designated by this parallel data; and since data ''1'' is stored previously in the designation address dependent upon parallel data in the vertical synchronizing signal period in this ROM, the vertical synchronizing signal of level ''1'' is obtained as the detection output in the period, when the pattern of parallel data obtained at every fixed timing and the parallel data pattern to designate the address where data ''1'' is stored previously agree with each other, namely, in the vertical synchronizing signal period. Thus, since the vetical synchronization detection dependent upon time series pattern is performed, the detection performance can be improved.

Abstract: PURPOSE:To simplify the setting operation and to correspond with an opposite station in a very short time by supplying an oscillation output from a local oscillator of a 2nd reception section selectively as an oscillation output for the setting to a transmission frequency to a transmission reception section. CONSTITUTION:An oscillation output of a VFO 24 for reception and an oscillation output of a VFO 25 for transmission via a changeover switch 41 are fed to a local oscillation input terminal 23 to decide the frequency of the transmission and reception of a transmission reception section 2. When a signal is sent to an opposite station received by a reception section 3, the oscillated frequency of the VFO 34 is fed to a local oscillation input terminal of the transmission and reception section 2 by throwing the changeover switch 41 to the position of a terminal T and throwing a changeover switch to the position of a terminal RXT. As a result, a signal is sent from the transmission reception section 2 in the frequency received by a reception section 3. Thus, the equipment acts like a radio communication equipment having substantially two transmission reception sections.

Title: Fm demodulating circuit
Inventor: KIMURA HIROYUKI
IPC: H04N5/922
Filed: 1980-10-17
Abstract: PURPOSE:To demodulate an FM signal, reproduced by a low-carrier FM type recoder, with less distortion, by extracting and adding the carrier components of the FM signal and by emphasizing the carrier components. CONSTITUTION:An FM signal having unbalance between both side-bands of a low carrier FM system is inputted to a limiter amplifier 2 after a signal in a unnecesary band is eliminated by a BPF1. After limiter amplification, the FM signal is inputted to the phase-locked loop PLL consisting of a phase comparator 21, an LPF22 and a voltage-controlled oscillator 23. Then, the LPF22 performs sufficient attenuation to a modulation frequency to put the oscillation signal of the voltage-controlled oscillator 23 in the same phase with the FM signal carrier of the input. A carrier extracted by the PLL Is added to the original FM signal to emphasize only the carrier signal. Then, the output of the adder 22 is detected by a detector 3 to perform distortion-free demodulation. Thus, the modulation is carried out with less distortion.
