Title: Polarizer
Inventor: OGURA TOSHIAKI
IPC: G02B5/30
Filed: 1989-10-18
Abstract: PURPOSE:To obtain a polarizer inexpensive and capable of using reflected light and with superior weatherability and possible to miniaturize by providing an optical element having a polarizing separation function on a substrate surface on the sawtooth surface of a first substrate with sawtooth cross-secion in a specific direction. CONSTITUTION:The optical element 12 having the polarizing separation function on the substrate surface is provided on the sawtooth surface of the first substrate 11 with cross-sectional structure of sawtooth shape in the specific direction. For example, a linearly polarized component 14 ins parallel with an incident plane out of natural light 10 made incident on the sawtooth oblique plane A of the sawtooth surface at incident angle 45 deg. is transmitted, and a linearly polarized component 13 perpendicular to the incident plane is made incident on an oblique plane B confronting with the oblique plane A after being reflected on the oblique plane A. Since the oblique planes A and B are provided with a common incident plane, the light 13 made incident on the oblique plane B is the linearly polarized component perpendicular to the oblique plane B, therefore, it is further reflected on the plane and returns in an incident direction. Thereby, it is possible to easily form an inexpensive and micro polarizer, and furthermore, to realize the one with superior weatherability such as heat resistance, etc., and to improve mass-productivity.

Title: Automatic operating device for air supplying fan
Inventor: SAKAHARA TAKASHI
IPC: F24F7/007
Filed: 1987-10-27
Abstract: PURPOSE:To permit stabilized comfortable ventilation without being affected by the opening and/or closing of a door or external wind, by a method wherein an air supplying fan is operated by a micro-computer so as to maintain a pressure difference between indoor and outdoor within an allowable range. CONSTITUTION:When an exhaust fan 2 is operated, a pressure difference between an indoor 10 and an outdoor 9 is generated at an outdoor side detecting port 8 and an indoor side detecting port 6. When the pressure difference has exceeded a specified pressure difference, a signal from a high pressure difference detecting sensor 11 is transmitted to a micro-computer. When it is confirmed that the signal has been continued for a given period of time, the rotating speed of an air supplying fan 4 is increased gradually to increase the amount of supplying air. When the signal from the sensor 11 has stopped after the signal is continued, the rotating speed of the fan 4 at that time is held to secure a given amount of supplying air. When the exhaust fan 2 is stopped or the amount of exhaust is reduced, the pressure difference between the indoor 10 and the outdoor 9 is reduced. When the pressure difference has become lower than the specified low pressure difference, the rotating speed of the air supplying fan 4 is reduced gradually by a signal from a low pressure difference detecting senser 12 and the rotating speed of the fan 4 at a time when the signal from the sensor 12 has been stopped continuously is held.

CONSTITUTION:A CPU 17 provides an output of a code representing power-on among remote control codes for VTR control by each manufacturer sequentially from a remote control module 4 and a video signal discrimination circuit 16 monitors the presence of a video signal on each occasion. When a manufacturer of a connected VTR is coincident with a manufacturer represented in an output code, since a power of a VTR 2 is turned on, a black back, white back or a black burst signal or the like is outputted from a video output terminal of the VTR 2 and the video discrimination circuit 16 discriminates the video signal by detecting the presence of, e.g. a synchronizing signal in the signals. The CPU 17 discriminates a manufacturer code outputted at that time to be a manufacturer of the connected VTR at present and stores the manufacturer name to a nonvolatile memory 18.

Filed: 1989-10-18
Abstract: PURPOSE:To obtain satisfactory damping characteristic outside band without making an element into a large scale by arranging neighboring resonator filters on a piezoelectric substrate so that their pairs of comb-line electrodes can be deviated mutually in the propagating direction of a surface acoustic wave. CONSTITUTION:Two resonator filters 12a, 12b are arranged by cascade- connection in two stages on the piezoelectric substrate 11. Also, the pair of comb-line electrodes 13 are comprised by arranging so as to engage the pair of comb-line electrodes 13a, 13b in which plural electrode fingers 15 are formed at a prescribed cycle lambda. The resonator filters 12a, 12b are arranged in such a way that respective pair of comb-line electrodes can be deviated by (lambda/2+nlambda) (n:0 or integer) in the propagating direction of the surface elastic wave i.e., half wavelength. Therefore, the influence of a component converted to a coupling or bulk wave can be suppressed even when standing wave components in the resonator filters 12a, 12b leak outside a waveguide. In such a way, the damping characteristic outside band can be improved even when the gap of the resonator filters 12a, 12b are narrowed.

The pressing piece 3a projected to both side edges of the lever piece 3 is bent so as to hold the overlapping part of the strip piece 2. The tip of the overlapping part of the strip piece 2 is then bent by overlapping it on the outside of the bent part of the lever piece 3. In this way an extremely strong composition is enabled because of the lever piece 3 being fitted without welding means.

Abstract: PROBLEM TO BE SOLVED: To prevent incomplete drying of a substrate in a substrate drying device. SOLUTION: In a substrate drying device 100 of a structure, wherein with the pressure within a chamber 111 decreased, a substrate 9 is rotated to perform drying treatment for the substrate 9, a roughly funnel-shaped discharge duct 113 is provided under the lower part of the chamber 111.
