Title: Tape cassette
Inventor: YOSHII TETSUJI
IPC: G11B23/087
Filed: 1984-06-26
Abstract: PURPOSE:To stabilize the tape drive and to improve the sound record/reproduction characteristics by securing such a constitution where a tape slide-contact surface having a high coefficient of friction has a slide-contact with a tape for a tape guide at the upstream side in a tape drive mode and a tape touching surface having a low coefficient of friction has a slide-contact with the tape for a tape guide at the downstream side, respectively. CONSTITUTION:When a tape 15 is driven toward an arrow A by a capstan and a pinch roller, a tape guide 4 is turned counterclockwise. Then the tape 15 is driven with a slide-contact secured with a sliding surface 4a having a high coeffieient of friction. When the tape 15 is driven toward an arrow B, the guide 4 is turned clockwise. Thus the tape 15 is driven with a slide-contact secured with a slide-contact surface 4b having a low coefficient of friction. The tape load, i.e., the difference of tension is obtained by the driving direction of the tape 15 after the tape passes through the guide 4. For a tape guide 5, however, the tape 15 has a contact with a sliding surface 5a of a high coefficient of friction when it is driven toward the arrow B and has a contact with a sliding surface 5b of a low coefficient of friction when it is driven toward the arrow A respectively.

Title: Air current regulator for elevator basket
Inventor: ONISHI KIHACHIRO
IPC: B66B11/02
Filed: 1990-05-23
Abstract: PURPOSE:To reduce the noise in a basket chamber by an air current in a low- cost constitution by providing an air current regulator having a number of semispherical recessed parts at a casing over and under the basket chamber and at an outer surface of the basket chamber. CONSTITUTION:Semispherical recessed parts 7 formed in the outer surface of a casing 4 and the outer surface of a side wall 2a of a basket chamber 2 are disposed in a large number randomly. With an air current regulator for an elevator basket composed like this, an air current generated by elevation of the basket chamber 2 passes along the outer surface of the casing 4 and the outer surface of the side wall 2a of the basket chamber 2 to be changed to a turbulent flow 9. Eddies 9a in the turbulent flow 9 takes motion energy from the air current 8 on the outer side, and the speed of the turbulent flow 9 is increased. As a result, a separation point is moved back to be eliminated, and the reattachment force is reduced, thereby noise transmitted to the basket chamber 2 is reduced.

Title: Polarized light guide plate and polarization surface light source
Inventor: MIYATAKE MINORU
IPC: G02B5/30
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To obtain a light guide plate which makes it possible to obtain exit light consisting of linearly polarized light and is capable of arbitrary controlling its polarizer direction (vibration plane). SOLUTION: This polarized light guide plate is constituted by laminating polarized light scattering plates 3 which dispersely contain micro regions having double refractivity and exhibits scattering anisotropy depending upon polarization directions on one or both substrate of a translucent resin plate 1. The polarized light scattering plates 3 dispersedly contain the micro regions consisting of liquid crystal polymers of >=50 deg.C in glass transition temperature which exhibit a nematic liquid crystal phase at temperature lower than the glass transition temperature of polymers forming transparent films in the films. There is no need for forming special light emitting means, such as reflection dot, on the translucent resin plate 1. Natural light is made incident from the flanks and the linearly polarized light is efficiently emitted from the front and rear surfaces.  The linearly polarized light of the prescribed vibration direction is obtained via the optical axis of the polarized light scattering plates 3. The vibration direction of the linear polarized light may be arbitrarily changed by the optical axis control of the polarized light scattering plates 3. In addition, the durability, such as thermal stability, is excellent.

Title: Transport device
Inventor: KUWABARA HIDEO
IPC: E04H6/20
Filed: 1992-04-24
Abstract: PURPOSE:To miniaturize the device and improve the function by linearly moving a parent carriage, moving a child carriage loaded on the parent carriage in the same direction, and letting the child carriage cross over an obstacle over which the parent carriage can not cross, so as to deliver or receive an object to be transported. CONSTITUTION:A longitudinal transport device 10 and a traverse transport device 20 are loaded on a frame base 2 of an elevator to deliver or receive a pallet 3 to be loaded on a vehicle. Next, at operating the device 10, a geared motor 13a is started, and a parent carriage 12 is moved up to the front end along a rail 11 through a chain mechanism. Next, a child carriage 15 loaded on the carriage 12 is moved in the same direction through a gear and rack mechanism interlocking with this movement, and let cross over the carriage 12 so as to protrude under the pallet 3. After engaging a traction device 7 on the carriage 15 with the pallet 3, the carriages 12, 15 are retreated so as to pull it into the base 2. Further, the device 20 is similarly operated. Hereby, the object can be delivered and received smoothly in a short time in perpendicularly crossing two directions, and the cost can be decreased because of low height of the device.

Title: Color toner concentration detector
Inventor: TANAKA TOORU
IPC: G03G15/08
Filed: 1983-07-21
Abstract: PURPOSE:To eliminate the effect on a photodetector of spectral reflected light due to a color toner on a conductive mask by arranging a conductive probe, a light emitting element, and the photodetector so as to render incident light from the light emitting element on the conductive mask different from the light incident on the mask, reflected from said probe and advancing toward the photodetector. CONSTITUTION:Light emitted from a light emitting element 9a passes through a conductive mask 11 at an incident angle i1, reflected from a conductive probe 8, and again passes through the mask 11 at an incident angle of i2, and reaches a photodetector 9b. Since the incident lights i1, i2 are given different values from each other, the light emitted from the element 9a and reflected from a color toner on the mask 11 at a reflection angle of alpha is not received by the element 9b.
