Abstract: PURPOSE: To prevent a deterioration in out-of-roundness caused by the deformation of a cylindrical conductive substrate at the time of assembling a flange into the end part of the conductive substrate and to obtain an excellent image by making the outside diameter of the part of an end part engagement member to be inserted into the end part of the conductive substrate larger than the inside diameter of the conductive substrate. CONSTITUTION: Gears 7b and 7c on both end parts of the drum-like cylinder 7a of a photoreceptor drum are provided with fitting parts 7b1 and 7c1 which are press-fitted into the end parts of the cylinder 7a respectively and the outside diameters (dN) of the fitting parts 7b1 and 7c1 are formed to be larger than the inside diameter DS of the cylinder 7a. After the gears 7b and 7c are press-fitted into both end parts of the cylinder 7a respectively, a part of the end parts of the cylinder 7a is caulked in several places and the end parts of the cylinder 7a are fitted into the recessed parts 7b2 and 7c2 of the respective gears 7b and 7c. Therefore, stress applied to the end parts of the cylinder, at the time of caulking is received by the fitting parts of the gears, so that the deformation of the cylinder 7a can be suppressed as little as possible.  Thus, the out-of-roundness of the photoreceptor drum is improved and the excellent image can be obtained.

Abstract: PURPOSE:To obtain a reproduced picture of high quality by using a recording and reproducing system which has some limited frequency band. CONSTITUTION:A luminance signal Y outputted from a generator 1 for a color TV video signal is amplified at a part 2 and then supplied as a signal wave to a frequency modulator 3, whose frequency-modulated signal is amplified at a part 4 and then supplied to a magnetic head 7 through the fixed contact R5 and movable contact a5 of a recording/reproducing changeover switch 5 to form a  recording track on a magnetic tape 9. Color difference signals outputted from  the generator 1, i.e. signals (R-Y) and (B-Y), on the other hand, are amplified at  parts 10 and 11.

Filed: 1983-08-12
Abstract: PURPOSE:To contrive to enhance precision of abrasion of a semiconductor substrate by a method wherein an abrasion resistant layer formed on the surface part of the substrate other than grooves and having an abrading speed lower than a buried material is utilized as a stopper against mechanical abrasion. CONSTITUTION:A material having hardness higher than an abrasive material to be used for mechanical abrasion is selected to form an Si3N4 film 3 to be formed on an SiO2 film 2 on a P type silicon semiconductor substrate 1. The surfaces of grooves 41, 42 are oxidized to form insulating films 6, and when a burying material 7 consisting of poly-silicon is deposited on the whole of the surface of the substrate 1, a recess 8 is generated on the surface of the brad width groove 42 part. To flatten the surface of the buried material 7 without receiving so much the influence of the recess 8, it is favorable to depend on mechanical abrasion. As an abrasive material, SiO2 powder having higher hardness than the poly-silicon of buried material 7, while having lower hardness than Si3N4 constructing the abrasion resistant layer 3 is used. Accordingly, the layer 3 having a slow abrading speed is made to function as a stopper against abrasion, and high precise abrasion can be attained extending over the whole of the surface of the substrate 1.

Abstract: PROBLEM TO BE SOLVED: To measure the accuracy of stitching of shots in a high accuracy. SOLUTION: A specified area on a substrate is exposed by a first shot including a mark 1, and then the substrate is positioned and another specified area on the substrate is exposed by a second shot including a mark 2.

Title: Energizing apparatus for hermetic motor
Inventor: NAGATO YUICHIRO
IPC: F24F11/02
Filed: 1986-06-25
Abstract: PURPOSE:To reduce an initial load current after automatic reset by detecting a load current to know the operating state of automatic reset type protecting means, and gradually raising the output of an inverter from a low value when it is automatically reset. CONSTITUTION:When the temperature of a motor armature winding 5a is a predetermined value or lower, the contact of automatic reset type protecting means 10 is closed. Accordingly, the output of current detecting means 13 holds the state L. When the temperature of the winding 5a exceeds a predetermined value, the contact of the means 10 opens, and the output of current detecting means 13 becomes H. Thus, the outputs of logic circuits 108, 110 become L, and a power inverter is interrupted at its base. A resetter 115 is operated to return the output of slow accelerating/decelerating command output means 102 to its initial value. When the temperature of the winding 5a drops and the contact of the means 10 closes, the output of the means 13 becomes L, and the output of the means 102 gradually rises.

Filed: 1978-11-27
Abstract: PURPOSE: To reduce work load needed to generate high-pressure gas, by generating the high-pressure gas by thermal gasifying a liquid nitrogen into gaseous nitrogen while holding its volume nearly constant.  
     CONSTITUTION: Liquid nitrogen in liquid nitrogen tank 3 composed of a vacuum jacket is activated by compressed-air pump 1 operated by air source 9 and then sent to heat exchanger 2 by way of non-return valve 17. Next, liquid nitrogen is heated in heat exchanger 2 to gasify by obtaining vaporing latent head and then rise in temperature by obtaining temperature-rising head before being stored in charge tank 4. In this process, since it is carried in liquid by pump 1, heated by exchange 2 and then gasified with its volume kept nearly constant. As a result,gas pressure rises greatly and high-pressure nitrogen gas is stored in charge tank 4. In addition, work load needed in this process is equivalent only to conveyance of liquid nitrogen and heating in the heat exchanger, so that the work load needed to generate high- pressure gas can be reduced.

Title: Blade angle control device for variable pitch marine propeller
Inventor: KITAURA HISAYOSHI
IPC: B63H3/10
Filed: 1983-08-11
Abstract: PURPOSE:To aim at enlarging the effective range of an automatic load control device, by providing such an arrangement that an initial set value is given to the blade angle of a propeller by anticipating load variations so that the deviation between the initial set value and a desired value is made small. CONSTITUTION:Acceleration signals S10 which are momentarily delivered to a blade angle compensating device 11, are successively stored in a memory, as acceleration data, and are analyzed by a computer after the lasting of a predetermined time period to obtain the time period, amplitude and phase of acceleration in order to anticipate a load variation after the time point. Meanwhile the compensating value of the blade angle which corresponds to the anticipated load variation and which minimizes the load variation, is calcuarated, and is converted into a blade angle compensating signal S11 which is then delivered. Thus, a set blade angle signal S2 is compensated by an adding and subtracting unit 8 in accordance with the signal S11 to a value approximate to the desired value, and the deviation between a set signal and the desired value is simultaneously corrected by the adding and subtracting unit 8 in accordance with a blade angle compensating signal 7 with reference to the rotational speed of the engine rotary system. Then, the final compensating signal 8' is delivered to a variable pitch marine propeller 9, and therefore, the blade angle control in addition to the feed-forward control may be smoothly followed up, thereby the effective range of the automatic load control device may be enlarged.

Abstract: PURPOSE:To reproduce a picture density the same by storing the picture data to a hard disk or the like while adding a density condition adjusted by the operator so as to U$6 the density condition when the same picture is reproduced. CONSTITUTION:A CPU 5 controls the entire system and allows each section to make following operations according to a program stored in a ROM 6. That is, when the operator commands print of picture data generated by a key board 4 while observing a CRT 3, a picture printer 2 prints out the picture data expanded by a picture memory 9. The operator discriminates whether or not the density of the picture is proper and stores tentatively a transfer charged voltage of the printer 2 to a RAM 7 as additional information. When not proper, the operator adjusts the density of the printer 2 properly and when the picture data are stored on floppy disk FD 8 or a hard disk HD 11, the additional information is revised and saved therein. Thus, the picture density is identically reproduced by using the additional information when the same picture is reproduced.
