Patent JP-H02219963-A (JP)
Title: Cold heat accumulation refrigerating cycle
Inventor: NAKAMURA HIROSHI
IPC: F25B13/00
Filed: 1989-02-20
Abstract: PURPOSE:To operate room cooling with a heat storage compressor by connecting a heat accumulation tank filled with heat accumulation material in parallel with an indoor heat exchanger, separately providing a looplike tube passing the tank to be thermally exchanged with the material, and providing a pump for circulating refrigerant in the tube. CONSTITUTION:When low temperature heat is accumulated in a heat accumulation tank 60 by using electric power at night, a compressor 10 is driven, a four-way valve 14 is closed similarly to that at the time of compressor only room cooling operation, and an outdoor fan 18 is turned ON in a state that a direct-drive two-way valve 70 is open and direct-drive two-way valves 24, 42 and reversible two-way valves 30, 74 closed. Both a pump 76 and indoor fans 28, 84 are turned OFF. Since the valve 24 is closed but the valve 70 is opened, low temperature and low pressure liquid refrigerant is supplied to a heat accumulation heat exchanger 66. When the liquid refrigerant is evaporated by the exchanger 66, it removes heat from heat accumulation material 64. The material 64 is solidified to store heat as latent heat. If the refrigerant is not sufficiently evaporated by the exchanger 66, an electronic control valve is reduced. Even if the temperature of the material 64 becomes near a solidifying point, return of the liquid refrigerant to the compressor 10 is effectively prevented.

Title: Fault point ranging device
Inventor: TSUKAMOTO JIYUNICHIROU
IPC: G01R31/08
Filed: 1981-03-18
Abstract: PURPOSE:To obtain easily the distance up to a fault point, by transmitting voltage values and current values at both ends of a transmission line. CONSTITUTION:When the voltage at a power transmission terminal, the current at said transmission terminal, the voltage at a reception terminal, the current at said reception terminal, the voltage at an accident point, and the resistance value of the transmission line between two transduction places are denoted as Vs, Is, Vr, Ir, Vx, and R1 respectively, a resistance value R1 from the transmission terminal to the accident point is equal to (Vs-Vr-Ir.R)/(Is-Ir). The voltage Vs and the current Is are transmitted through a transmission device 8, and Vs-Vr-Ir.R and Is-Ir are obtained by adders 10 and 11 at the reception terminal and are inputted to a dividing circuit 13 to obtain the resistance value from the sending transmission terminal end to the accident point. However, since Is=Ir is true when the transmission line is indefectible, it is necessary to provide a switch 12 which is closed when an accident is detected in the input part of the divider.

Title: Setting structure for fuel tank
Inventor: AKEDA HISATOSHI
IPC: B60K15/067
Filed: 1983-03-15
Abstract: PURPOSE:To make the service life of a tank prolongable, by engaging a locking device movably in a relative manner with both setting brackets secured tight to both fuel tank and body framework sides via ineffective holes, while clamping the locking device in a way of making both these setting brackets into the state that there is no initial strain in them. CONSTITUTION:At each of setting brackets 4 and 6 in each fixed part of bolts 8 and 9, relative movement comes to be possible sideways to each of bolt holes 4a and 6a which are designed so as to become ineffective. A tip end of the bolt 8 engaging with the bolt hole 4a is inserted into the bolt hole 6a. Since these bolt holes 4a and 6a are of ineffective ones, the bolt hole 8 is possible for relative movement in a horizontal direction whereby the setting bracket 4 at this side of a tank 1 is mounted on the setting bracket 6 at the both sides of a body framework 3 in the state that no strain occurs. Under no strain condition, when the nut 9 is engaged to the tip end of the bolt 8 and clamped tight, both these brackets 4 and 6 are firmly locked in the state that there is no initial strain at all.

Title: Production of ferrite core for magnetic head
Inventor: YAMAUCHI MICHIAKI
IPC: G11B5/133
Filed: 1987-02-26
Abstract: PURPOSE:To permit easy supply of glass thinly and uniformly to track grooves and decrease of air bubbles in the glass by coating pasty glass powder in the track grooves and calcining the coating. CONSTITUTION:The viscosity of the glass powder decreases and the easy infiltration of the pasty glass powder into the deep part and end edges of the fine track grooves is permitted when the glass powder is prepd. into the pasty state by an org. solvent or the like. The grain size of the glass powder is selected adequately with respect to the track grooves, by which the infiltration of the pasty glass into the track groove is made much easier and the uniform coating of the glass is permitted. Since the glass is fine powder, the side effect of a decrease in the melting temp. of the glass is obtd. in calcination and since the molten glass powder spreads to all the corners in the track grooves, there is an advantage that the air bubbles are decreased. Furthermore, the coating by brushing, etc., is possible and the workability is improved as the glass is prepd. in the pasty state.

CONSTITUTION:A simultaneous circuit 1 is connected in parallel with a discrimi nation circuit 2 inputting a color difference line sequential signal, inputting a chroma blanking(C-BLK) signal and outputting a line pulse(LP) signal. Through the constitution above, the line pulse(LP) timing at recording is discrimi nated by using a color difference line sequential signal, that is, R-Y/B-Y through- signal, R-Y/B-Y delay signal and a chroma blanking(C-BLK) signal. Then the line pulse(LP) of the same phase as that of the discriminated line pulse(LP) is used for the simultaneous circuit 1 to minimize the unevenness caused during the chroma blanking(C-BLK) period. Thus, the color with fidelity to the record ing signal is reproduced on a monitor without giving adverse effect onto the succeeding circuit.

Title: Ink jetting recorder
Inventor: JINNAI KOUICHIROU
IPC: B41J2/185
Filed: 1979-04-07
Abstract: PURPOSE:To prevent the contamination of the equipment affected by wind and to recover the unnecessary ink accurately by arranging the gutter at the front and on the side of the head in such a manner that the tip of the gutter on the side is higher than the gutter at the front. CONSTITUTION:A gutter 52' is provided on the horizontal side of the head to recover unnecessary ink drops horizontally deflected when the gutter level is arranged below the printing line. At this point, the right head becomes less in the vertical deflection because of shorter flying distance. To overcome this, the tip of the gutter is set higher than the front gutter 52 to align the jetting position of the nozzle. This also allows the side gutter 52' to serve as one end of the wind preventing cover.
