Title: Formation of phase type hologram
Inventor: YAMAGISHI FUMIO
IPC: G03H1/20
Filed: 1982-03-30
Abstract: PURPOSE:To set a Bragg angle in reproduction optionally, by using a basic hologram with low diffraction efficiency for forming a phase type hologram having high diffraction efficiency and a different Bragg angle on the hologram, and obtaining double-layer structure. CONSTITUTION:The basic hologram 1'' with low diffraction efficiency formed on a glass substrate 2 is coated with a specific amount of a photosensitive agent to form a photosensitive agent layer 7. Then, the substrate 2 is irradiated on the reverse side with light 30 to expose the layer 7, forming a longitudinal section of interference fringe along the intermediate line between the transmitted light 31 and diffracted light 32 of the hologram 1''. By a treatment after the exposure, the phase type hologram 7' having high diffraction efficiency and a different Bragg angle from that of the hologram 1'' is formed. In this double-layer constitution, the upper layer hologram has the high diffraction efficiency and the hologram of the lower layer is disregarded, thereby setting the Bragg angle in reproduction optionally.

Filed: 1980-04-21
Abstract: PURPOSE:To prevent the electron emission function of a cathode from being damaged by providing means that all mutually jumpering the pin connection areas of a socket in which base pins are inserted and closing them during knocking. CONSTITUTION:Electromagnetic relay contacts 11, 11, and 11 are connected between the terminals of a socket 2 in which the base pins of a picture tube 1 are inserted. Simultaneously with this, the base pin connection areas can mutually be jumpered by providing an electromagnetic relay coil 12 which drives the contacts. During knocking, the electromagnetic relay 12 is excited and the contacts 11, 11, and 11 are closed. Knocking is performed by applying approximately eight times as high voltage as in service from a knocking power supply 9. During aging, the contact 11 is opened and aging power 10, 10, and 10 is supplied to the respective grid electrodes 3, 4, and 5. This does not generative any potential differece between the grid electrodes including cathodes even if pulse current is applied to the electrode in which intra-tube discharge occurs during knocking. As a result, the cathode can be prevented from being damaged.

Filed: 1988-03-07
Abstract: PURPOSE:To uniformly and efficiently cool and aggregate and to enable good concrete placing at an arbitrary period or place by vertically providing a passage along the inside of a vacuum cooling vessel and sucking water evaporated in the aggregate. CONSTITUTION:An aggregate K is introduced into a vacuum cooling vessel 1 before kneading concrete therewith and temp. of the aggregate K is lowered by gasifying and evaporating water incorporated in the aggregate K. Many passages 4 such as a gutter type are vertically fitted in parallel to the inner wall surface of the vacuum cooling vessel 1 and water evaporated in the aggregate K is sucked through them. Further the passages 5 sectioned into several steps are provided to the central part of the inside of the vessel 1 and the joints are formed into an inserted type so that the aggregate K can not enter but only the evaporated water S can pass through. Both a steam ejector 10 and cooling 23 are actuated just before water contained in the aggregate K starts to evaporate. When evaporation of water in the aggregate K starts, temp. of the aggregate K is lowered by the amount of heat equivalent to that of evaporation. Thereby the aggregate K can be uniformly cooled and quality of concrete after placing can be improved.

Filed: 1979-04-27
Abstract: PURPOSE: To prevent the main thrust engine from overload by comparing the output indication signal level from main thrust engine with its allowable maximum level, then correcting the propeller pitch setting signal level and setting the pitch.  
     CONSTITUTION: The action of level 1 causes a reducing valve 3 to set the pitch setting pressure. When said setting pressure is below the setting pressure of a reducing valve 8 set to be maximum output level of main engine, the pitch setting pressure is not reduced but supplied through three-way valve 14 or 15 to the variable pitch propeller drive mechanism 19 because the pistons 4b and 4c of unit 4 move respectively up and down to fully open the reducing valve 4d. When the pitch setting pressure exceeds over said maximum level, the output shaft 6 increases the main engine output indicating pressure of the reducing valve 7 and said indication pressure moves the pistons 4c, 4b respectively up and down to close the reducing valve 4d. The pitch setting pressure is reduced by integrating element 9 or 13 to the maximum while being exhausted through a valve 4d, and said reduced setting pressure is supplied to the variable pitch propeller drive mechanism 19.

Filed: 1979-04-27
Abstract: PURPOSE: To enable sufficiently high speed travel even with insufficient driving power of a small-sized battery, by constituting to travel at reduced frictional force by floating the shutter blades with electromagnetic force.  
     CONSTITUTION: Due to magnetic repulsion of permanent magnets 3b, 3a and a permanent magnet 1b, a front blade 1 floats in the gap in a guide part 3. In the shutter charge state, electric power is not supplied to a front blade driving part 4, and both ends of a permanent magnet 2 provided in the front blade 1 are attracted and held by an electromagnet 4a at the left end or the corresponding upper electromagnet. When the shutter is released, electromagnets 4aW4g on the upper and lower sides are successively energized by a segment for exposure 6a, a slide segment 5 and a common segment 8, and the both ends of the permanent magnet 2 float in the space. At the same time, the front blade 1 suddenly moves to the right and the rear blade follows it to perform exposure. Then the shutter is reset similarly. Thus, even with a small-sized battery, the shutter may be allowed to travel at a sufficiently high speed.

Abstract: PROBLEM TO BE SOLVED: To prevent heat generation caused by consecutive strobe light emission by preventing photographing operation for a 2nd specified time in the case the number of light emitting times attains a specified value and subtracting the specified value in the case strobe light photographing is not performed for a 1st specified time. SOLUTION: When the counted value of a counter circuit 9 attains the specified value, photographing operation is prevented from being performed for the 2nd specified time and a discharge tube 2 is started by a photographing circuit 6 so that strobe light may be emitted, by which a series of photographing operation is executed. Meanwhile, every time the strobe light is emitted, the value of the counter circuit 9 is added. When the 1st specified time elapses, the lower limit value of the counter circuit 9 is set to '0', the specified value is subtracted from the counted value of the counter circuit 9, then a timer circuit 7 is restarted. Namely, in the case the strobe light emission is repeated until the 1st specified time elapses, the addition of the counted value of the counter circuit 9 is performed.  When the counted value attains the specified value, the photographing is prevented from being performed and subtraction of the value of the counter circuit 9 is performed every time the 1st specified time elapses.
