Inventor: TANABE TSUNETOSHI
IPC: F25D23/08
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a heat insulation structure of ceiling of a refrigerating room, Merein the room can be constructed with an on-site foaming, and a dispersion of stress is enhanced by rationally making use of an inherent properties of heat insulating foamed resin material, thus effectively preventing a rupture and a peeling-off of a heat insulating layer. SOLUTION: A steel-made heat insulation structure of a ceiling of a refrigerating room is constructed by mounting a heat insulating layer 5 on an upper surface of a hung ceiling substrate 4 which is made of steel. The heat insulating layer 5 is a combination of grid-like reinforcing frame 9 which is mounted on the ceiling substrate 4 and a heat insulating foamed resin member 8 which is overlapped on the reinforcing frame 9. The reinforcing frame 9 is made of members having a high strength such as wooden members or light gauge sections which are arranged in a grid pattern on the upper surface of the hung ceiling substrate 4. The heat insulating foamed resin member 8 is produced by foaming a heat insulating foaming material on the reinforcing frame 9 on site.  The reinforcing frame 9 is mounted on the hung ceiling substrate such that a plate-like partition member 7 is inserted between the reinforcing frame 9 and the heat insulating foamed member 8, wherein such a partition member 7 determines a lower limit of the heat insulating foamed member 8 so as to prevent the direct contact of the heat insulating foamed member 8 with the hung ceiling substrate 4.

Title: Current mirror circuit and driving circuit of light emitting element using the current mirror circuit
Inventor: NAKAYAMA HISAKI
IPC: H03F3/343
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress a layout area in order to increase the accuracy by using a vertical transistor for a PNP transistor which constitutes a current mirror and using a lateral transistor having a larger current amplification factor than the vertical one in its operating current region, for a PNP transistor for power supply compensation. SOLUTION: A V(vertical) PNP transistor can cause current to flow but has a low current amplification factor Hfe. Inversely, an L(lateral) PNP transistor has a high Hfe at the lower current side but cannot cause large current to flow,. Therefore, the collector of a VPNP 2 is connected to the input of a current mirror 1 and the emitter is connected to a power supply Vcc and the base is connected to the base of a VPNP 3 whose emitter is connected to the power supply. To the common base of the VPNPs 2, 3, the emitter of an LPNP 4 is connected. The collector of the LPNP 4 is connected to the ground potential and the base is connected to the collector of the VPNP 2. Due to this structure, the increase in an element area can be suppressed and the accuracy can be increased compared with the case where only one type of transistors are used.

Title: Magnetic recording medium
Inventor: AZUMA HIROSHI
IPC: G11B5/702
Filed: 1989-04-12
Abstract: PURPOSE:To obtain a magnetic recording medium having excellent durability and electromagnetic conversion characteristics by using a polyurethane-urea resin comprising polyester diol containing 3-methyl-1,5-pentane diol as a binder component. CONSTITUTION:Such a polyurethane-urea resin comprising polyester diol containing 3-methyl-1,5-pentane diol is used to prepare the binder component. As 3-methyl-1,5-pentane diol has a methyl group in its side chain, it enhances the solubility of the obtd. polyurethane-urea resin in an org. solvent. This enhances the concentration of urethane couplings in a molecule and the solution has low viscosity even when urea couplings are introduced. Thus, the magnetic coating material can be applied as in a high-solid state. By using the polyurethane-urea resin with improved solubility in an org. solvent as the binder component for the magnetic layer, the obtd. medium is excellent in durability and electromagnetic conversion characteristics.

Abstract: PURPOSE:To accurately adjust parameters with a simple constitution by installing a rotating direction switching circuit which compares the output parameter of a unit to be  adjusted with a prescribed atandard parameter and outputs a signal which brings the  output parameter close to the standard value. CONSTITUTION:A unit to be adjusted 1 has a trimmer condenser CC and the adjustment  is performed by controlling the rotational operation with a pulse motor Mp. When an  oscillated output of the unit 1 is inputted into a comparator 2, the comparator 2 measures the output for a fixed time and outputs a code signal through a terminal 2a and a  rotary pulse through another terminal 2b. Moreover, the comparator compares the inputted frequency with a normal-frequency stored in the comparator 2 through a terminal 2c, and outputs a binary signal ''1'' when the inputted value > the normal value,  and ''0'' when the inputted value < the normal value, to a reversing direction switching circuit 3. The circuit 3 compares the level of frequencies before and after the adjustment, and then, compares the result of the comparison with the rotating direction  indicate signal from the signal 2b. Then, the circuit 3 outputs a signal which brings the  frequency close to the standard value to a driving mechanism DS corresponding to the  changing direction of the frequency of the previous stage stored, and adjusts the condenser CC by driving the motor Mp.

Title: Television receiver
Inventor: MAJIMA ISAO
IPC: H04N5/44
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce a transient time of a television receiver where a picture at channel switching is disturbed. SOLUTION: A control section 20 allows a synchronizing signal generator 30 to supply a vertical synchronizing signal VDa to a vertical deflection circuit 25V in the case of switching a channel CH1 into a channel CH2, where the phase of the vertical synchronizing signal of the channel CH1 is sequentially delayed at a phase step Td and coincident with the phase of the channel CH2 at an M-th step. Since the vertical synchronizing signal of the channel CH2 after the switching and having a large phase difference Tp from the phase of the vertical synchronizing signal of the channel CH1 before the switching is not directly fed to the vertical deflection circuit 25V, the vertical deflection system smoothly traces the vertical synchronizing signal.  Thus, a time t1 until the vertical synchronization system is synchronous with the vertical synchronizing signal of the channel CH2 after the switching is decreased more than that of a conventional television receiver. Thus, a transient time where a picture at the switching is disturbed can be reduced.
