IPC: G02F1/133
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of realizing a display mode permitting to give an analog-like and elegant impression. SOLUTION: After a display output Dout is switched off and display contrast Lout becomes 0 and a display pattern has disappeared, a display gray level Vout also becomes a low gray level after a prescribed time, and a liquid crystal driving voltage drops. Thereafter, although the display output Dout is switched on to display another display pattern, the display gray level Vout then remains low, therefore, the display pattern does not appear. Immediately or in a prescribed time after the display output is switched on, the display gray level Vout gradually increases to reach a normal gray level before long.

Title: Air conditioner
Inventor: ITO MIKIO
IPC: F24F1/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To obtain an air conditioner having excellent deodor performance by incorporating a deodor element provided with a photocatalytic layer being irradiated with UV-rays to decompose odorous components. SOLUTION: A deodor element 15 is disposed on a blow-out channel 14 on the downstream side of a fan 11 in a ventilation passage from indoor air inlets 5, 6 to an air outlet 9. Since the air flowing through the blow-out channel 14 has high current velocity, the quantity of air flowing while touching deodor element 15 is increased per unit time. Consequently, the entire indoor air can be deodorized in a shorter time and deodor performance is enhanced and since a desired deodor performance can be sustained even if the deodor element is reduced in size manufacturing cost can be decreased while making compact the entirety.

Title: Duct hose
Inventor: AKETO YOICHI
IPC: F16L11/08
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce ventilation resistance without curving/projecting a hose wall inside even when a hose is bent by projecting the inner peripheral side hose wall of the bending part outside in the radial direction of the hose when the hose is bent. SOLUTION: A duct hose 1 is composed of an inside/outside surface almost smooth hose wall 2 formed by joining the mutual adjacent side edges by fusion by winding a flexible vinyl chloride resin (PVC) tape in a spiral shape and a rigid PVC spiral reinforcing body 3 attached in a spiral shape to the outside surface of the hose wall 2. While a hose wall 2A of the bending part outer peripheral side 4 presents a straighter line shape by being pulled in a bending state, a hose 2B of the bending part inner peripheral side 5 is constituted so as to project outside in the hose radial direction, that is, in the same direction as the spiral reinforcing body 3 by being contracted. Ventilation resistance is reduced since the inside surface is smooth in an ordinary straight pipe state, so that a ventilation loss can be remarkably reduced by maintaining the effective inside diameter without hindering a fluid flow by the hose wall even in a bending state and a contracted state.

Title: Fan forced heater fitted with air cleaner
Inventor: SUZUKI TOMIJI
IPC: F24H3/04
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To stop the operation of fan forced heating and prevent the transformation of resin parts and the damage caused by the heat of main parts, by opening a shutter provided in the bypass air duct of an air cleaning part at the time of operation of a fan forced heating part alone, and intermitting the air cleaning part. SOLUTION: At heating operation, warm air is sent out of warm air blowout port 5 at the bottom of the front so as to perform heating by a convection fan 4. At this time, the air cleaning part is in intermittent operation, and the shutter provided in a bypass air duct is open, and a temperature detector 21 monitors normal temperature. When an obstacle is placed in the vicinity of the hot air blowout port 5, the warm air hits on the obstacle and comes close to a grill 15. At this time, since a fan 12 for air cleaning is in intermittent operation, the warm air is blown in. The temperature of the warm air becomes 100 deg.K at maximum. Here, the temperature detector 21 detects this warm air, and conveys it to a controller 23, and when it comes to a certain temperature or over, the controller 23 stops the heating operation, and prevents the transformation of resin parts.

Title: Method for heating liquid crystal and apparatus therefor
Inventor: OKA HIDEO
IPC: G02F1/1341
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently warm a cell by blowing heated gas to the cell at the time of filling liquid crystals into the cell. SOLUTION: A fan 53 and heater 54 in a unit box 52 are driven simultaneously with the start of a liquid crystal filling operation or slightly before the same. The air in a vessel 10 is sucked by driving of the fan 53 into a duct 51 through a suction port, by which the air is heated in the process of passing the heater 54. The air is blown off in the form of hot air from the duct 51 to a hood 55. The hot air is subjected to the removal of dust by a filter 57 and to the removal of static electricity by an ionizer 58 and is thereafter blown to the cell 1 from the holes of a gap forming material 59. The cell 1 is thus rapidly warmed. The liquid crystals filled into the cell 1 are warmed by the heat from the warmed cell 1, by which the viscous resistance thereof is lowered.  Consequently, the liquid crystals are more easily filled into the cell 1 and the time for packing the liquid crystals is shortened.

Title: Floating head of magneto-optical recording type recorder
Inventor: MURAKAMI AKEMI
IPC: G11B11/10
Filed: 1990-12-18
Abstract: PURPOSE:To simplify the production of the floating head by forming a magnetism generating means of a magnetic field generating coil which is wound over the entire periphery on the side face of a floating body and nearly in parallel with an optical recording medium. CONSTITUTION:The magnetic field generating coil 43 built in the floating head 4 is energized to generate the perpendicular magnetic field in the direction reverse from the magnetization direction of a magnetic film 10 of a magneto- optical disk 1 at the time of recording information with this recorder. On the other hand, the laser beam from the semiconductor laser modulated in correspondence to recording information is converged toward the magnetic film 10 surface of the magneto-optical disk 1 via a collimator lens, beam shaping prism, beam spliiter, relay lens, and reflection prism 26 to direct the magnetization direction of this part reverse from the ambient, by which the recording of the information is executed. The need for providing the groove for mounting the coil 43 on the floating body 41 is eliminated in such a manner and the number of turns of the magnetic field generating coil 43 wound on the side face of the floating body 41 can be made large than heretofore. The production of the floating head is thus simplified.
