IPC: F28D1/047
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To eliminate the fault due to abnormal wind noise and condensed water by forming a plurality of cutouts at one side of a heat transfer fin in the longitudinal direction, and bending the cutout of the fin at the outside in the longitudinal direction, thereby facilitating the bending without lowering the heat exchanging performance. SOLUTION: A plurality of refrigerant tubes 12 are inserted into and engaged with a plurality of heat transfer fins 13, which have cutouts 14 to become a bent outside. The cutouts 14 are expanded by a bending machine, and heat exchanger is bent and formed in a predetermined shape. Accordingly, the heat transfer area is not reduced, and the heat exchanging performance is not reduced as well. Since the fins 13 are not cut at the bent inside, abnormal wind noise is scarcely generated. The bending is facilitated, the condensed water is continuously fed from the upper part to the lower part of the fins 13, thereby eliminating the storage of the water near the cutouts 14 or the fault of scattering the dew.

Title: Thermal transfer recording sheet
Inventor: KAZAHAYA NOBUAKI
IPC: D21H27/00
Filed: 1986-12-17
Abstract: PURPOSE:To contrive higher image reproduction properties, by providing a plasticizer-containing resin layer between a receiving layer and a base, in a thermal transfer recording sheet comprising the receiving layer, to which a sublimable dye in a coloring material layer of a thermal transfer sheet is transferred to achieve recording according to image information, and the base for supporting the receiving layer. CONSTITUTION:A receiving layer is provided on the surface of a base, with a plasticizer-containing resin layer provided therebetween, to obtain a thermal transfer recording sheet. With the plasticizer-containing resin layer thus provided between the base and the receiving layer, it is made possible to contrive a higher image density without impairing preservability of transferred images. Since the resin layer contains a plasticizer, it shows a favorable cushioning property at the time of transferring, and is capable of preventing a vibration or ununiformity in density from being generated upon printing. A resin constituting the plasticizer-containing resin layer may be, for example, a polyester or a thermoplastic resin such as a vinyl chloride resin, a vinyl acetate resin, a styrene resin and an acrylic resin.

Title: Voice-coil motor
Inventor: KISHI YUJI
IPC: G11B7/09
Filed: 1994-12-05
Abstract: PURPOSE: To obtain a voice-coil motor which suppresses the generation of a resonance in a translation mode by a method wherein a screw is installed at a side-yoke part which is faced with a magnetic pole for a permanent magnet and a moving yoke part is brought close to, or separated from, the permanent magnet. CONSTITUTION: When a screw 15 is turned, the protrusion amount of the screw 15 from a yoke 10 is changed, and a gap interval between the tip of the screw 15 and a permanent magnet 8 is changed. When the gap interval is made small, the magnetic resistance of a gap is reduced, and a magnetic-flux density inside the gap is increased. In addition, when the gap interval is made large, the magnetic resistance of the gap is increased, and the magnetic-flux density inside the gap is reduced. When the magnetic-flux density of a magnetic gap 12 is adjusted, it is possible to absorb the difference between driving forces due to an irregularity, in an inside-gap magnetic-flux density B, and that, in an effective length 1, which are generated between respective gaps 12, 13.  Consequently, both driving forces acting on a coil 3 can be made to agree, and the generation of a translational force can be suppressed. That is to say, when the gap interval is adjusted by the screw 15, a resonance in a translation mode can be prevented.

Title: Level converting circuit
Inventor: MATSUMOTO KOJI
IPC: H03K19/018
Filed: 1987-11-27
Abstract: PURPOSE:To reduce a delaying time by executing a level shift by means of a diode train in which plural diodes are connected in a forward direction instead of the level shift by means of resistances. CONSTITUTION:In stead of the level shift by means of the resistances, the level shift is executed by the diode train composed of plural diodes connected in the forward direction. Namely, a first diode train composed of a first resistance R1 and three diodes D3, D4 and D5 are connected in series between a positive power source voltage VCC and a grounding potential GND, and a threshold voltage at which a first diode D1 is turned on/off is decided. The potential at the anode side of the diode D1 is level-shifted from the positive potential to the negative potential by a second diode string composed of a first transistor Q1, diodes D7 and D8 composed between the VCC and a power source voltage VEE and by a constant current source ICS 1. Such a signal is further level- shifted by an emitter follower circuit composed of a second transistor Q2 and a second resistance R2, and it is made into an output signal. Thus, the delaying time by the parasitic capacity and wiring capacity of elements can be reduced.
