Title: Switching regulator
Inventor: SUMI AKIRA
IPC: H02M3/335
Filed: 1978-07-31
Abstract: PURPOSE: To enable the use of a switching regulator for an AC voltage and for a DC voltage even if the difference between the voltage is large, by equalizing the chopping frequency of a chopper circuit to the oscillation frequency of a DC/DC converter.  
     CONSTITUTION: The chopper circuit 1 and the DC/DC converter 2 are connected in series with each other. The not-yet-rectified high-frequency rectangular voltage (e) produced on the secondary side of the transformer T of the DC/DC converter is integrated by an integration circuit 5 to generate a triangular wave of small amplitude to equalize the chopping frequency to the oscillation frequency of the converter. Thus, the switching regulator operates properly even if an input voltage Vi fluctuates greatly. Therefore, the switching regulator can be used for the AC voltage 100V and for the DC voltage 23V. Even if a load RL changes, the oscillation frequency is almost constant because of the properties of the DC/DC converter. Since no pulse generator is needed, the construction is simplified.

Title: Supporting fitting for conveyor belt
Inventor: NAKANO TAKAO
IPC: B65G15/60
Filed: 1992-04-13
Abstract: PURPOSE:To facilitate the mounting and demounting of a conveyor belt by installing at least one of a pair of rotary bodies in a shiftable manner. CONSTITUTION:A pair of rotary bodies 2 are installed in turnable manner on a main body 1, and the vicinity of the basic edge of the outer peripheral thick part 30 of a conveyor belt 3 is nipped, and the inward shift of the conveyor belt is suppressed. At least one rotary body 2A of a pair of rotary bodies 2 is screwingly joined through a slot hole 11 penetrating through the main body 1, and fixed on the main body 1 so as to be shifted in the direction separating from the other rotary body 2B. When the conveyor belt 3 is demounted, the screw joint is loosened, and the rotary body 2A is shifted in the direction separating from the rotary body 2B, and the belt 3 is demounted in the state where the interval between the rotary bodies 2 is spread. Accordingly, the need of demounting by releasing the screw joint of bolts and nuts as in the past is obviated.

Title: Automatic focusing device
Inventor: OTSUKA YASUNOBU
IPC: G03B13/36
Filed: 1987-04-14
Abstract: PURPOSE:To perform accurate focusing operation by selecting the deviation quantity where the movement distance of an image formation optical system is minimum along deviation quantities from plural focus positions which are outputted by an automatic focusing detecting means. CONSTITUTION:An AF detecting means 2 detects the focus deviation quantity of an image formed on an estimated focal plane by the image formation optical system 1 and its detection output is inputted to a focus position selecting means 3. Then when an automatic/manual operation member 4 selects and performs AF driving, a focus position selecting means 3 selects the deviation quantity where the movement distance of the image formation optical system 1 is minimum among quantities of deviation from plural focus positions which are inputted by the AF detecting means 2. A driving motor 5 rotates on receiving the output of this focus position selecting means 3 and a moving mechanism 6 is AF-driven to a focus position. When the automatic/manual operation member 4 selects manual driving, the moving mechanism is operated and driven manually to change the plural deviation quantities, thereby minimizing the deviation quantity of the focusing of a subject that a photographer intends.

Abstract: PURPOSE:To stabilize a metal hub with a hub bearer by specifying an area as a magnetizing area which extends along a center line connected from one end of an edge part of the hub bearer including a part corresponding to a positioning hole to an area including a rotary shaft inserting hole into which a rotary shaft is inserted but no to reach the other end of the edge part and specifying the remaining part as a nonmagnetizing area. CONSTITUTION:The area extending along the center line connected from one end of the edge part of the hub bearer 30 including the part corresponding to the positioning hole 7c to an ellipsoidal area including the rotary shaft inserting hole 30b without reaching the other end of the edge part is specified as the magnetizing area 31, and the remaining part is specified as the nonmagnetizing area 32, thus magnetizing partially the whole area to be unbalanced. When such a hub bearer is used, relative weakening of magnetic attraction force in the vicinity of the positioning hole 7c of the metal hub 7 can be covered. Consequently, the overall balance of the magnetic attraction force of the hub bearer 30 as against the metal hub 7 at the time of positioning a magnetic disk 6 is improved. By this method, without increasing torque force required for positioning the magnetic disk, the metal bub 7 can be stabilized with the hub bearer 3.

Title: Network environment display method
Inventor: KAMEDA MASAMI
IPC: G06F3/048
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To visually recognize throughput between nodes by displaying throughput between the nodes on a screen in the thickness or the color of a line showing a network. SOLUTION: When network management software down-loads data from respective servers 202-204, it measures time required for down loading and the size of data and calculates throughput by dividing the size of data by time required for down loading. A network between a management terminal 201 and servers 202-204 is displayed by the thickness of lines 205-207 corresponding to the value of the throughput. In such a case, the network can be displayed by the thick line as the throughput is larger, for example. A network manager can visually recognize that the throughput of the network between the management terminal 201 and the server 202 is the largest by viewing the screen.

Title: Recording apparatus and its manufacture
Inventor: SATO SHUJI
IPC: B41J2/32
Filed: 1995-03-27
Abstract: PURPOSE: To prevent a recording material from flowing out of a recording part thereby securing good recording at all times, by providing the uppermost surface layer where an opening exposing the recording part is formed, making the opening larger than an area of the recording part, and setting a flow prevention means like a loop at an area of the enlarged opening to surround the recording part. CONSTITUTION: In a noncontact type printer of a dye evaporation model, a dye-storing part 87 is formed like a recess in an insulating plate 73 of SiO2 at a dye evaporation part 77 of a printer head 70. A group of minute columnar bodies 80 is set as a part of an evaporation structural body 101 at the storing part 87. A protecting layer 91 with an evaporation hole 91a is formed at a surface opposite to a bottom plate 102. The inside of the evaporation hole 91a accordingly becomes the evaporation part 77. A liquid fluororesin is injected in an annular groove 73a at an area of the insulating plate 73 exposed by the opening 91a, and then dried thereby to provide a liquid stop part 97 to surround the evaporation structural body 101. In this manner, a liquid dye 22 is prevented from flowing out of the dye-storing part 87.

Title: Manufacture of photoconductive material
Inventor: SHIMADA JUICHI
IPC: H01L31/08
Filed: 1987-04-17
Abstract: PURPOSE:To obtain a photoconductive material which has a higher spectral sensitivity in a short wavelength region by a method wherein the deposition is made to be performed on a substrate whose temperature range is below a specified temperature. CONSTITUTION:Si and graphite are sputtered in an Ar atmosphere which contains hydrogen (H2) at various mixing ratios of 30% or less by mol as a high frequency discharge is made to take place and deposited on a substrate for the formation of a thin layer. In this process, it is desirable that the temperature of the sample substrate is made to be selected from those ranging from room temperature to 300 deg.C. The temperature between 150-250 deg.C is the most practicable. If a temperature is too low, hydrogen is hard to be introduced into an amorphous material, and when a temperature is too high, on the contrary, hydrogen is released from the amorphous material. By these processes, an amorphous material of this design is made to have a sensitivity peak for a wavelength optionally chosen from those ranging from 5600Angstrom  to 4500Angstrom .
