Title: Printing position adjustor
Inventor: MUKAI SHIGEO
IPC: B41J19/18
Filed: 1986-06-12
Abstract: PURPOSE:To enable adjustment of deviations in printing positions according to the printing direction of a printer, by providing a variable delay circuit capable of regulating a delay time for input signals and a logical circuit for selectively outputting the printing signals according to a control signal. CONSTITUTION:When an input signal 8 is at a high level, an input signal 7 is outputted as an output signal 9 after being passed through an OR gate 5 and a delay circuit constituted of a variable resistor 1 and a capacitor 2. The delay of the signal is determined by the variable resistor 1 and the capacitor 2, and the delay time is set by the variable resistor 1. Deviations in printing positions due to rightward printing and leftward printing by a printer arise from errors in a carrier motor. By shifting the timing of a printing head by an amount according to the error, it is possible to print at proper positions.

Title: Semiconductor device
Inventor: URABE JUNICHI
IPC: H01L23/36
Filed: 1986-06-12
Abstract: PURPOSE:To prevent the warping of a semiconductor chip, by providing a thin semi-insulating layer and a metal layer having excellent heat conductivity between a buffer layer and a semi-insulating substrate, and decreasing thermal resistance. CONSTITUTION:A thin semi-insulating layer 3' and a metal layer 4, which is connected to a PHS metal layer, are provided between a buffer layer 2 and a semi-insulating substrate 3. Heat, which is yielded at an active layer 1, reaches the metal layer 4 through the buffer layer 2 and the insulating layer 3'. Since the heat conductivity of the metal layer 4 is excellent, the most part of the heat is transferred to the PHS metal layer 5 on the side surface of a semiconductor chip through the metal layer 4. Since the insulating layer 3' is thinner than the substrate 3, heat resistance is reduced as a result. Thus, the warping of the semiconductor chip is prevented.

Title: Hot air room heater
Inventor: YAMAGUCHI MASAO
IPC: F24H9/02
Filed: 1994-06-20
Abstract: PURPOSE:To prevent hot air from flowing to the inside of a front plate by a method wherein the lock end part of a horizontal blade part is inserted in the comb-shaped groove for inserting the horizontal blade of a lowered part and a gap between the lateral frame of a hot air blow-off frame and the front plate is closed with the cut rise part. CONSTITUTION:A lock end part 2a of a horizontal blade 2 is fixed to a lateral frame part 3 of a hot air blow-off frame 1 and a lock end part 2a of each horizontal blade 2 is inserted in a comb-shaped groove 12 for inserting a horizontal blade having a bent lowered part 11 formed in a hot air blow-off opening edge 10 of a front plate 4 disposed at the front of a hot air blow-off frame 1. In this case, the bending width of the lowered part 11 has size enough to reach the lateral frame part 3 of the hot air blow-off frame 1 and the lowered part 11 forms a partition wall. This constitution blocks inflow of hot air to the inner side of the front plate by the lowered part when an obstacle is placed in front of the hot air blow-off port and eliminates a fear of deformation of a part such as a base leg made of resin owing to the increase of temperature.

Filed: 1994-06-21
Abstract: PURPOSE:To increase the outputting amount of transmitting pulses from a spectrum reducing device by reducing the spectrum lobe and to improve the reception S/N of an interrogator, and then, to accurately process distance measuring signals. CONSTITUTION:The modulator of a DME/P ground device reduces or discretes a spectrum lobe in a specified band by adding a correcting signal which is changed in frequency, phase, and amplitude to the second half section of the waveform of a modulating signal which modulates the amplitude of high-frequency input signals. A clock signal having a frequency based on a delayed modulation trigger S100 delayed at a delay circuit 141 is outputted to a correcting waveform memory 143. A correcting signal, S12a from the memory 143 is inputted to a voltage divider 145 through a D/A converter 144 and the signal S12a is adjusted to the level of the spectrum lobe and added to modulated signals from a digital waveform generator 119. The resultant signals are inputted to a modulator 109 and inputted RF signals S108 are outputted from an amplifier 110 as transmitting pulse signals (response pulses) S112 after the amplitude of the signals S108 is modulated with a synthesized modulated signal S133.

Title: Steam recovery mechanism of hot water circulation device
Inventor: MATSUMOTO MOTOKI
IPC: F24H1/38
Filed: 1989-05-31
Abstract: PURPOSE:To allow the mechanism to minimize the frequency of water supply by providing an atmospheric pipe on the upper part of an open top tank and an auxiliary tank connected with a water feed pipe on the lower part thereof and further setting a steam recovery mechanism arranging a pipe, an upper cover and a clearance on the cap of said auxiliary tank. CONSTITUTION:A pipe 8 loosely engated with a through hole 7' allows its outside to be covered with an upper cover 9 to be positioned through a funnel-shaped part of a cap 7 of the upper cover 9 and a clearance (A). For this reason, when air containing steam is pushed from the pipe 8 into the upper cover 9, the air stays in the upper part of the upper cover 9 because the air is warm and the other air which does not contain steam in the upper cover 9 is exhausted from the clearance (A) outward. In addition, when the outside air is sucked, the air containing steam which stays in the upper part of the upper cover 9 is allowed to flow in an auxiliary tank 6 through the pipe 8 and the steam is recovered as it is. On the other hand, when the steam is liquidized on the inner wall surface of the upper cover 9, water droplets are received in the funnel-shaped part of the cap 7 through the inner wall surface to return to a tank 6 from the clearance of the pipe 8 and the through hole 7' so as to recover the liquidized steam.

Title: Combustion wick
Inventor: UTAGAWA TOSHIO
IPC: F23D3/08
Filed: 1980-10-01
Abstract: PURPOSE: To suppress the generation of a tar substance in the combustion wick and to obtain a stabilized cobmustion condition for a prolonged period of time by a method wherein the surface of a vaporization section of the combustion wick is covered with a heat resistant inorganic substance such as a heat resistant inorganic paint.  
     CONSTITUTION: A fuel (f) is sucked up from a sucking wick to a main wick 1 and vaporizes from the surface of a fuel vaporization section 3. In this case, a part of the fuel (f) transforms itself into the tar substance (t) due to the temperature and oxygen around the surface of the top end of the fuel vaporization section 3. To prevent this, the surface of the fuel vaporization section 3 is covered with the heat resistant inorganic paint 4 becuase, by so doing, the interior of the covered fuel vaporization section 3 is brought under an oxygen deficient condition and the fuel (f) is hard to become the tar substance (t) which is produced as a result of oxidation polymerization. Further, even in case where a part of the tar substance (t) is accumulated within the main wick 1, the tar substance (t) is pyrolized into a low molecular substance (t') as the temperature in the main wick 1 rises up, and is then vaporized.
