Title: Transmission type display device using polarizing plate
Inventor: HIROKI TSUTOMU
IPC: G09F9/00
Filed: 1979-02-06
Abstract: PURPOSE: To make possible displaying of only one content on the same display surface by forming the display body through superposition of plural polarizing plates with their axes of polarization being inclined with each other and radiating polarized light to this dispaly body through arbitraty selection of its main direction.  
     CONSTITUTION: Polarizing plates 14, 16 are superposed with their mutual axes of polarization being inclined about 90°, whereby a display body 10 is formed on a turbid color sheet 12. Thence, the polarized light which is obtained by passing the visible light of a light source 20 through a ploarizing disc 22 is radiated to the display body 10. Thereby, the content of either of the plates 14, 15 is projected onto the sheet 12 owing to the relation of the axes of polarization. For example, when the main direction of the polarized light is orthogonal to the axis of polarization of the plate 14 and is parallel to the axis of polarization of the plate 16, the polarized light passes through the plate 16 and is absorbed by the plate 14 and therefore the content of the plate 14 is displayed on the sheet 12. As a result of this, the main direction of the polarized light may be selected as desired and the contnt of only one direction of the either one may be projected on the display surface.

Filed: 1980-02-07
Abstract: PURPOSE: To make easier molding by bending and make the assemblage of impeller better by folding circumferentially a combined slit and rib into a rectangular form.  
     CONSTITUTION: A steel plate 1 of a doughnut shape is provided with slits 2 and 3 extending radially from outside circumferential portion to inside, respectively.

Filed: 1987-01-22
Abstract: PURPOSE:To reduce quantizing noise by providing a means for deciding the optimum multipulse train based on a pitch estimation while using the previously, preparatorily and provisionally decided multi-pulse train as an object. CONSTITUTION:A H'(Z)/H(Z) converter 1 is what is called an acoustic sense weighted filter and converts the filter of a transmission function H(Z) which sets an alpha parameter received from k/alpha converter 4 as a filter factor into a filter, which a voice input is made to pass through so as to execute a noise shaping as a preprocess. Now, gamma is a damping coefficient which is set in the range of 0<gamma<1 and a damping coefficient calculating unit 5 offers it as the form of gammaalpha. The damping coefficient calculating unit 27 multiplies the inputted alphaparameter by the damping coefficient gamma and transmits gammaalpha to an LPC (linear estimation encoding) composite filter 26. The value of gamma, in such a case, is previously set like an analysis side. The LPC composite filter 26 which receives the gammaalpha utilizes it as a filter coefficient and forms a total polarity type digital filter having a transmitting relation H'(Z).

IPC: G01L9/00
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a pressure sensor which decreases an offset voltage and can lessen a temperature dependency of a sensitivity. SOLUTION: A substrate of single crystal silicon is processed from a rear face thereof by anisotropic etching with the use of an aqueous solution of potassium hydroxide (KOH) or the like, thereby forming a thin part at a central part of the substrate. A diaphragm 1a is obtained in this manner. A strain gauge is formed on the diaphragm 1a, whereby a silicon chip 1 is manufactured. A surface where a pressure introduction hole 2a of a silicon pedestal 2 is formed is bonded to the silicon chip 1 by a silicone adhesive 4, and the other face of the silicon pedestal 2 is bonded by the silicone adhesive 4 to a face where a pressure introduction hole 3a of a package 3 is formed. Since the pedestal is formed of the same material as that of the silicone chip 1, the base and the silicon chip has the same thermal expansion coefficient.  Accordingly, a strain of the silicon chip 1 due to a temperature change is restricted. Moreover, owing to the bonding by means of the silicone adhesive 4, an offset voltage resulting from the strain at the bonding time is reduced.
