Abstract: PURPOSE:To improve the efficiency of heat transfer by providing a cold heat storage body comprising a tube and a supporting rod, said tube containing water and a weight and said supporting rod attached to said tube in a manner that the bottom part of the tube is positioned a little away from the bottom of the supporting rod and near to its middle. CONSTITUTION:A plurality of supporting rods 113, each of which is attached to a tube 112 containing water 111 and a weight 114, are bound within a frame 118 with the bottom of each of the supporting rods 113 under the bottom of the tube 112 so that a bundle of cold heat storage bodies 120 are capable of standing by themselves with the supporting rods 113 as leg. Therefore, the bundle of cold heat storage bodies 120 can be placed at any position in a heat storage tank when no antifreeze liquid is in use in the heat storage tank. After the heat storage tank has been filled with an antifreeze liquid, the frame 118 is set at a lower position than the level of the antifreeze liquid; the frame 118 then serves as a spacer between the cold heat storage bodies 119 which are used in a plurality, allowing the antifreeze liquid to flow vertically along the frame 118 and hence circulate smoothly.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent a size disagreement of images between a first and a second faces of a paper by correcting in accordance with a predetermined magnification value for the first face which is to be printed earlier, partial data corresponding to the second face which is to be printed later among document data of a printer which carries out printing to both faces and, generating print data.

In the case of printing to both faces, for example, when a printer language is to be generated by a print driver 12 and a language analysis part 13 before the language is sent to a print engine 18, an image of a face which is to be processed to be printed earlier among two front and rear faces of the paper is multiplied by a correction magnification value so that an image of the face which is to be processed for printing later is reduced. A normal relative size is maintained between images printed to a first face and a second face of the paper without mechanically controlling the print engine 18.

Title: Tape cassette recorder and/or reproducer
Inventor: MURAKAWA YORIO
IPC: G11B15/675
Filed: 1982-04-15
Abstract: PURPOSE:To eliminate the inconvenience involved in the latching, by locking a latch type plunger solenoid to a non-latch position when a tape cassette is not loaded and then releasing the locking of the solenoid when the loading of the tape cassette is detected. CONSTITUTION:While a tape cassette 4 is not loaded ket to a recorder/reproducer and carried, a slide plate 11 is moved toward an arrow X1 and then locked by a lock bar 20 to receive the limit for shift toward X2. Thus it is impossible for a plunger 10a and the plate 11 to move toward X2. Therefore a latch type plunger solenoid 10 is kept under a non-latch state despite application of a big impact to eliminate the inconvenience in which an injection button cannot be pushed. When the cassette 4 is loaded, the bottom surface of the cassette 4 presses the top 25a of a detecting pin 25. Then the pin 25 presses down the bar 20, and an arm part 20c comes out of a notch 11d. As a result, the locking of the plate 11 is released. Thus the plate 11 moves toward X2. Then reel desks 2 and 3 are released from a damping state respectively.

Title: Digital optical communication receiver
Inventor: WATANABE KENJI
IPC: H04B10/07
Filed: 1986-03-20
Abstract: PURPOSE:To attain the decision of 1, 0 level without error from a waveform having an amplitude fluctuation in an optical reception signal level due to a modal noise by controlling a threshold voltage level depending on the change in the eye pattern. CONSTITUTION:If a modal noise takes place, the amplitude of signal is changed rapidly, and since an equalizing amplifier 2 cannot equalize the signal, the peak value is changed as shown in figure in the output. A detection circuit 6 detects the change and inputs the result to a control section 7. The control section 7 changes the threshold voltage Vref in the range of Vref'-Vref'' so as to minimize the distortion of the reproduced output based on the detection signal. Thus, even if the reception signal amplitude has a variation, the threshold voltage is kept to a prescribed voltage relation with respect to the reception signal amplitude so as to minimize the code distortion.
