Abstract: PURPOSE:To provide an optical sensor having high S/N by using functional thin film laminates having different electrical conduction types and/or conductivity and different band gaps and contg. a prescribed value or below of hydrogen as a 1st and 2nd photoconductive bodies. CONSTITUTION:An electrode 102 is formed on a glass substrate 101 and thereafter, a 1st photoconductive film 104A and a 2nd photoconductive film 104B are formed thereon; further, an electrode 103 is formed thereon. The respective films 104A, 104B are constituted of the laminates of >=two kinds of the functional thin films. The respective functional thin films have the respectively different band gaps and the respectively different conduction types and/or conductivity. In addition, the films contain <=10atom.% hydrogen. Then, the dense film quality is obtd. and the traveling property of minority carriers is improved. Since the diffusion length of the carriers is eventually increased, the electrical and optical characteristics of the films are improved. The optical sensor having the high S/N is thus obtd.

Abstract: PROBLEM TO BE SOLVED: To enhance reliability while reducing the size and cost by providing a pattern connecting with a printed board in a region other than a region where means for connecting a pressure generating means with a plane other than that provided with the pressure generating means is formed. SOLUTION: Discrete end face terminal on the side of end face not facing each piezoelectric element in each array of piezoelectric elements is connected with discrete lead-out electrode on a substrate 3 through a conduction processing material. Each discrete lead-out electrode and a common electrode are conducted with a connection pattern, i.e., a rear surface discrete electrode pattern 33 and a rear surface common electrode pattern 35, through through-hole electrodes 23, 25, respectively. A printed board, i.e., an FPC, is connected at a connection region (connecting part, contact part) with a flexible print cable FPC and applied with a drive voltage. Consequently, a field is generated in the laminating direction and an elongation is induced in the piezoelectric element in the laminating direction.

Title: Document producer
Inventor: AOKI HIROYUKI
IPC: G06F17/21
Filed: 1983-04-28
Abstract: PURPOSE:To reduce the operating load when a document is produced by displaying the format information on a display device with shift of a cursor to display the document contents and at the same time displaying the contents of the format information in an area different from a display area. CONSTITUTION:A memory part 12 contains an area where the document information is stored and an area where the format information is stored in response to each line forming a document. The document information is read out of a document information memory area and displayed on a CRT20. Then an optional position of the document displayed in the document information memory area on a display screen is designated by cursor shift keys 40-43. At the same time, the space character intervals are designated by a space key 49 and a next candidate key 45. In such a way, a cursor is shifted to display the document information. While the contents of the format information are displayed in a format display area set separately from the document information memory area. Thus the load of an operator can be reduced for production of documents.

Title: Feed pump of distribution type fuel injector
Inventor: YANAGAWA HAJIME
IPC: F02M37/04
Filed: 1981-05-16
Abstract: PURPOSE:To obtain a desired advance angle by pulling the vanes in the number less than the number of vanes of a pump in the direction of a shaft core by a pulling spring, and varying and supplied oil pressure. CONSTITUTION:An unbalanced vane pump 2 is equipped with a plurality of vanes 2c, and one 2c' of the vanes is pulled in the direction of a shaft core by the pulling spring 2e in a groove 2d'. Therefore, the vane 2c' is applied with the centrifugal force due to revolution, but the top edge of the vane 2c' does not contact to the internal wall surface of a cam ring 2b because of the pulling force of a spring 2e, until a prescribed number of revolution, for example 1,500 revolution is attained. When the centrifugal force applied to the vane 2c' exceeds the pulling force, pumping action with four leaves of vanes is started, and the oil feeding pressure Pt increases sharply. Therefore, if the starting point of compression of a timer spring is set close to the sharp increasing point of the supplied oil pressure, a desired advance angle T.A can be obtained sharply in proportion to the sharp increase of the supplied oil pressure.

Title: Image storage medium
Inventor: NISHIDA TOSHIO
IPC: G02F1/135
Filed: 1984-04-14
Abstract: PURPOSE:To store an image which is already outputted and to output the same image repeatedly by composing the image storage medium of a photosensitive layer and an image storage layer. CONSTITUTION:A DC voltage V is applied to transparent electrodes 2 and 8 and the image storage layer 10 is irradiated with light. This light is transmitted through a protection layer 9 and the transparent electrode 8 to reach a photoconductive laye 7 to make the part irradiated with the write light L conductive. The part which is not irradiated with the write light L is still transparent, so an opaque black insulating layer is seen in black as a background when viewed from the opposite side of the irradiation side. Liquid crystal 4 has an image storing function, so an image transferred to and stored in the image storage layer 10 is held even after an electric field is removed. The image is erased only by applying a high-frequency electric field which is more intenser than a threshold value electric field to the phase shift of the cholestic phase and nematic phase of the liquid crystal 4 between the transparent electrodes 2 and 8.

Filed: 1985-04-10
Abstract: PURPOSE:To reduce COD, SS, chromatility, etc. of secondary treated water of night soil remarkably and simultaneously by adding powdery active carbon and an inorg. flocculant to secondary treated water of night soil, then separating solid from liquid using a drum type screen. CONSTITUTION:Powdery active carbon and an inorg. flocculant (e.g. poly AlCl3) to secondary treated water of night soil, then the solid in the water is separated from liquid with a drum type screen (e.g. microstrainer). As compared to conventional process using an inorg. and org. flocculant in combination, a drum type screen having higher efficiency such as microstrainer is useful in this process because stronger and more stable floc is formed by the effect of active carbon serving as seed. Furthermore, simultaneous improvement of COD, SS, chromatility, etc. is possible unlike conventional process using combination of an inorg. and org. flocculant. Accordingly, the installation cost, maintenance and administration cost, etc. are reduced. The installation area is reduced and the operation and administration technique are simplified.

Abstract: PURPOSE:To make the displaying form automatically distinguishable whether it is numeric form or aplhanumeric form so as to simplify the device at a base station and, at the same time, to make manual switching possible by providing a form confirming circuit, form switching circuit, manual changeover switch, display section, etc. CONSTITUTION:Signals from a base station are received by an antenna 1 and stored in a displaying content storing section 8 through an FM receiver 2, decoder circuit 3, etc., and, at the same time, sent to a form confirming circuit 9 where the displaying form of the information signals is discriminated whether the numeric displaying form or alphanumeric displaying form. The displaying form discrimination is performed in such a way that the received information is once converted into the alphanumeric displaying form and whether or not control characters are contained in the converted information is discriminated. When no control character is contained, the displaying form is discriminated as the alphanumeric displaying form and, when the control characters are contained, as the numeric form. Information of the discriminated results is displayed on a display section 6 through a form switching circuit 5. Moreover, when a subscriber has a doubt to the displayed information, he can forcibly switch the displayed information by means of a manual changeover switch 10 and, furthermore, registration of all subscribers is not required. Thus the device at the base station can be simplified.
