Title: Transmission type projection screen
Inventor: IZAWA AKIRA
IPC: G03B21/20
Filed: 1982-07-09
Abstract: PURPOSE:To reduce the thickness of a device and to guide projection light effectively in an observation direction, by arranging the light-transmissive surface having a saw-tooth wave in cross section whose slanting surfaces and vertical surfaces are formed at nearly equal angles and pitch repeatedly, at least on an incident light source side. CONSTITUTION:Vertical surfaces 7 perpendicular to the flat rear surface of a screen 4' and slanting surfaces 8 having a specific angle are arranged alternately at nearly equal pitch to form the saw-tooth wave section. Light beams 9, 10, and 11 incident to the light-transmissive screen 4' are refracted in incidence and projection to obtain projected light beams 9', 10', and 11', and even when they are incident slantingly to the normal of the screen 4, they are refracted and projected in parallel to the normal, so mirrors 2' and 3', and surfaces 5' and 6' are arranged nearly in parallell, reducing the depth of the device. The slanting surfaces and vertical surfaces of the saw-tooth wave section are adjusted to refract the projected light to an observers' position.

Filed: 1983-07-01
Abstract: PURPOSE:To switch a displayed switching pattern with high efficiency by catching the shadows of fingers operating a switch by an image sensor via a semi- transmission type liquid crystal display and deciding the switching operation by a central processor. CONSTITUTION:The shadows of fingers operating a switch are caught by an image sensor via a semi-transmission type liquid crystal display, and the switching operation is decided by a central processor. For instance, a program is started to display the 1st switching pattern to a liquid crystal display LCD1 after a power supply is applied to this device. Then the switching pattern is stored to a CCD image sensor 8 by the signals of a control circuit 10, and the image signals are read into a CPU12 via a binary coding circuit 11. The CPU12 compares the reference signal of said switching pattern with the image signal. Then it is decided that no switching operation is carried out if the coincidence is obtained from said comparison. While it is decided that the switching operation is carried out if no coincidence is obtained. Then the switching pattern of the LCD1 is switched to the next pattern in case a mode switch (a) is operated.

Title: Power shovel revolution braking device
Inventor: KITO HIDENORI
IPC: E02F9/22
Filed: 1988-05-19
Abstract: PURPOSE:To have precise location of an upper revolving body even on a slope by actuating a revolution brake even within a delay time when the revolving speed of the upper revolving body becomes below a specified value. CONSTITUTION:When a revolving lever device 2 is put in neutral position, a revolution brake actuating signal is emitted from a revolution brake control device 1 to a revolution brake device 9 after a certain delay time. Therein the revolving speed of an upper revolving body is sensed by a revolving speed sensor 4 after the revolving lever device 2 is put in neutral, and if the result from sensing becomes below specified value, a revolution brake signal is sent out even within the delay time. An appropriate delay time is calculated by a delay time generating means on the basis of signal from the revolving speed sensor 4. This eliminates free operation of the upper revolving body on a slope etc. and also avoids disturbance due to gravity etc.

Title: Semiconductor device having random number generating circuit
Inventor: TAGIRI HIROKAZU
IPC: G06F7/58
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent random numbers from being equal at all the time by starting operation of a random number generating circuit without applying an initial value after a power source is turned on wherein the number of clocks to be inputted for a fixed time from the start of operation is not determined. SOLUTION: After power source is turned on and an oscillation circuit 1 is stabilized, resetting of an entire system is released, and after the lapse of a prescribed time, random numbers are read out. Thus, after resetting of the entire system is released, random numbers are always read out at the same timing. But, a random number generating circuit 4 is not initialized after the power source is turned on and further, the oscillation circuit 1 is started while its oscillation waves are unstable, so the operation is started without an initial value, and the number of clocks inputted for the lapse of a fixed time from the start of operation is not determined and random numbers are different at all the time.

Title: Production of deuterium concentrated water
Inventor: SHIYARURU MANDORIN
IPC: C01B5/02
Filed: 1982-07-12
Abstract: The synthesis gas plant is operated in n successive periods. During the first period, fresh water in excess is supplied to the synthesis gas plant (1) and the waste water from the resulting mixture is separated in a condenser (8) and supplied to a storage container (25). During the next (n-1) operating periods the waste water stored in the container (25) is used as freed water for the synthesis gas plant (1) and the waste water obtained on each occasion is stored in layers, depending on its deuterium concentration, in the container (25). The waste water having the highest deuterium concentration, obtained during the last operating period, is introduced into a second container (24) and supplied therefrom to a heavy-water plant. In order to recover deuterium from the gas mixture leaving the condenser (8) and consisting of hydrogen, steam and residual components, the gas mixture is introduced into an exchange stage (38), in which the gas mixture is brought into isotope exchange in counter-current with additional water, as a result of which the additional water becomes enriched in deuterium and is supplied to the synthesis gas plant.

Filed: 1990-05-14
Abstract: PURPOSE:To reduce the manufacturing efficiency, cost by providing caterpillars, facing each other, composed of compression plates rotating on the same rotary body and supporting both ends of respective plates by means of pressure applying devices. CONSTITUTION:Slurry of a plate material is fed from a feeding section 2 into a frame 11 on a belt 13.

During said process, slurry is transferred forward by the rotation of the belt 13 and compressed by a compression roller 12, and voids in the slurry generated by dehydration are crushed to further upgrade dehydration properties. Calcium silicate thus formed into almost a plate shape is inserted between compression plates 23 and 33 of upper and lower caterpillars 3 and 4, and compression molding is carried out by the weight of the upper side caterpillar 3 and adjusted pressure applied by pressure applying devices 5 and 6.

Title: Production of magnetic recording medium and device for producing magnetic recording medium
Inventor: KAWANA TAKAHIRO
IPC: G11B5/85
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To form protective coating on a magnetic recording medium without generating abnormal discharge and the wrinkling of a nonmagnetic supporting body, as a reaction tube bringing a gaseous starting material to chemical react with plasma, by using the one in which the edge part at the inside of the side opposite to a cylindrical can has been subjected to chamfering. SOLUTION: In a CVD device, since the edge part 9b at the inside of the side of the opening part 9a of a reaction tube 9 has been chamfered, the concentration of plasma in the edge part 9b can be suppressed. Thus, the generation of the wrinkling of a nonmagnetic supporting body 1 caused by plasma concentrated on the edge part 9b which becomes a problem in the case the width W of the reaction tube 9 is narrower than the width B of the nonmagnetic supporting body can be prevented.  Moreover, in the case the width W is wider than the width B, abnormal discharge generated between the reaction tube 9 swelled out from the width B of the nonmagnetic supporting body 1 and the edge part of a cylindrical can 8 swelled out from the nonmagnetic supporting body 1 becomes a problem, but, the concentration of plasma at the edge part 9b can be suppressed, so that this abnormal discharge can be prevented.
