Title: Reflection koehler illumination device for projection optical system
Inventor: IWASAKI SATOSHI
IPC: G02B27/00
Filed: 1988-02-10
Abstract: PURPOSE:To miniaturize a projector by illuminating the image of an original such as a film, etc., placed on a reflecting element through a projection lens, reflecting an illuminating light transmitted through the original by the reflecting element and illuminating the original from the back face in order to project the image. CONSTITUTION:The illuminating light 9 from a light source lamp 6 is condensed by a reflecting mirror 7 and a condenser lens 8, reflected downward by a half mirror 5 to form the image of the light source in the entrance pupil En.P of a projection lens system 1. Said En.P is under conjugate relation with the exit pupil Ex.P of the projection lens system 1, so that the illuminating light 10 whose light source image is a second light source in this position transmits a film 11, is reflected by the reflecting element 12 placed on an original platen 4 and illuminates the same image part of the film 11 from the back. Then, the illuminated image of the film 11 transmits the half mirror 5 by a projecting lens system 1, and an image is projected and formed on an upper screen 13. Therefore, a case for illuminating is formed compact and a projector can be made compact.

IPC: G06V10/10
Filed: 1980-03-13
Abstract: PURPOSE:To increase the efficiency with a simple constitution for an optical character reader, by controlling the reset pulse of an image sensor through a pulse generating circuit. CONSTITUTION:The image sensor 10 consists of plural shift registers that extracts successively the output signals of the photoelectric transducer group, and is driven by the driving pulse generating circuit 11. Then the output of the sensor 10 is processed by the signal processing circuit 13, and the pulse generating circuit 12 generates the pulse corresponding to the reading time. Here the sensor 10 of the circuit 11 and the reset pulse are controlled by the circuit 12, and then the output signal of the sensor 10 is controlled. Thus the pseudo frame signal is obtained from the image sensor to ensure a normal operation of the signal processing circuit of the rear stage by controlling the reset pulse of the image sensor through the circuit 12 although the carrying mechanism of the object to be read stands still. As a result, the efficiency can be increased with a simple constitution for an optical character reader.

Title: Printing apparatus and image processing method and apparatus
Inventor: KIMURA TAKEO
IPC: B41J5/30
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To reduce printing data while keeping image quality by putting together nozzles used in printing in a block unit and changing the size of this block based on the feature of an image. SOLUTION: An image is divided into blocks each having a predetermined size and it is judged whether the blocks are uniform in color. If the color is uniform, the code of the color is outputted with respect to the blocks and, if the color is non-uniform, the blocks are bisected longitudinally and laterally and each of the blocks is divided into four blocks and a code to the effect that resolving power is changed is outputted. It is judged whether the divided blocks are uniform in color. If the color is uniform, the color code thereof is outputted. This operation is repeated until all of the blocks become color codes. At a time of decoding, the pattern corresponding to the decoding of resolving power at that point of time is outputted in the case of the color code and the same processing is performed with respect to the code succeeding thereto in the case of the changeover code.  By this constitution, the reduction of data quantity and high image quality can be reconciled.

Abstract: PURPOSE: To minimize deterioration of transmitter filling time by providing a transmission means with a plurality of transducers operating at different frequencies to split a receiving region into a plurality of receiving strips thereby avoiding superposition of a receiving lattice side lobe and a transmission beam. CONSTITUTION: A transmission means 58 having a plurality of transmission transducers 59-61 of different frequency is employed to project a sound wave in desired pattern for receiving strips 62-64. A single hydrophone array is employed in order to form a total beam even if the frequency of the transducers 59-61 is different and the length thereof is limited in order to prevent excess deterioration of the filling time. In this regard, the length L of a transmitter to be equal to the width of strips 62-64 receiving a sound wave is set equal to or shorter than (2×R×FT)<1/2> . (R is shortest distance, FT is maximum allowable deterioration of filling time). According to the arrangement, performance of a sonar at a shortest distance R can be maximized by maximizing the interval of hydrophone.

Abstract: PURPOSE:To readily produce a wide range of carbamic acid derivatives by carrying out the transesterification of an unsaturated carbamic acid ester as a raw material with an alcohol, a primary or a secondary amine or an oxime. CONSTITUTION:An unsaturated carbamic acid ester of formula I (R is H or 1-8C alkyl; R<1> is residue obtained by removing OH from an alcohol) (e.g. ethyl N-methacryloylcarbamate) is made to react with an alcohol (e.g. 2-ethylhexyl alcohol), a primary or a secondary amine (e.g. methylamine) or an oxime (e.g. acetaldehyde oxime) at 40-150 deg.C to afford the objective unsaturated carbamic acid derivative in which OR<1> in the compound of formula I is substituted (e.g. 2-ethylhexyl N-methacryloylcarbamate). Since the reaction proceeds without especially requiring high temperatures and a catalyst, this method is advantageous. Furthermore, the produced carbamic acid derivative is a compound of formula II, III or IV (R<2> is R<1>; R<3> and R<4> are alkyl, etc.; R<5> and R<6> are alkyl, etc.).

IPC: F15B11/02
Filed: 1986-02-15
Abstract: PURPOSE:To obtain a control valve, which can give a variety of operation, by suitably changing the current supply value to a proportional control valve in each pilot valve. CONSTITUTION:A fluid control device is provided with main valves 10-40, current control relief valves 51-54, which act as the first to fourth pilot valves in order to control the main valves, respectively, and switching valves 60-90. By suitably changing the value of the current supplied to the current control relief valves 51-54 in each pilot valve, a variety of operation can be obtained. For instance, if the supply current value is made lower than the preset value and moreover the pilot pressure given to the third oil chambers R13-R43 is made lower than the preset pressure, the flow passage between the first oil chamber R11 and the second oil chamber R12 is suspended, thereby maintaining the pressure in each load flow passages P2 and P3. Thus, the fluid actuator A connected to the load flow passages P2 and P3 can be kept in a stopped state even when a load acts on the actuator A.
