Title: Optical head and photodetector used in the head
Inventor: AIKO HIDEKI
IPC: G11B7/135
Filed: 1994-06-24
Abstract: PURPOSE:To eliminate the adverse effect on each signal detection area by a stray light generated in an optical head and to stably detect focus error signals, tracking error signals and information signals. CONSTITUTION:In a photodetector 6 of an optical head, stray light carrier absorbing regions 6G and 6H which have same characteristics of signal detection regions 6A, 6B, 6C, 6D, 6E and 6F are arranged so that they practically fill in the gaps among the regions 6A to 6F. For example, when a stray light is generated in the optical head and stray light spots 10A and 10B are formed in the regions 6G and 6H, the carriers generated by the stray light in a semiconductor substrate 110 are absorbed by the regions 6G and 6H. Thus, the generation of unwanted signals, which are generated by the stray light carriers entering into each signal detection region, is prevented.

Filed: 1982-08-18
Abstract: PURPOSE:To obtain a composite roll having high quality, by using members produced by compression molding of metallic powder to a high density by utilizing a conventional press machine for the part corresponding to the outside layer of the composite roll and subjecting these members to diffusion joining to each other or to an inside layer formed of an ingot material by utilizing thermal expansion. CONSTITUTION:Annular members 14 which are divided to n parts in an axial direction in the part corresponding to the outside layer of a composite roll are formed of metallic powder by using a conventional press machine. The height (h) of the members 14 is made smaller than the outside diameter (d) thereof to form the moldings having a uniform density. Such members 14 are sintered and are then laminated and diffusion joined, whereby the outside layer of the composite roll is formed. The diffusion joined outside layer is combined with a rod (inside layer) 1 formed of an ingot material and is canned with a vessel 15 made of steel. The inside layer 1 and outside layer 14 canned with the vessel 15 are finally swaged hot to make the layer 14 compression-molded of the metallic powder and to forge-weld the inside and outside layer, whereby the intended composite roll is formed.

Title: Variable clamping circuit
Inventor: SUZUKI MASAMI
IPC: H02J1/00
Filed: 1994-05-31
Abstract: PURPOSE:To hold an output voltage within a proper constant range at all times by connecting clamping element groups which differ in clamp voltage in parallel and placing and operating the clamping element group which is large in clamp voltage in an area where the source voltage is low and the clamping element group which is small in clamp voltage in an area where the source voltage is high. CONSTITUTION:The clamping element groups 2 and 3 which have the mutually different clamp voltages are connected between the output voltage VCP of a charge pump 1 and the source voltage VDD in parallel. Before the clamp voltage by the clamping element group 2 which is large in clamp voltage exceeds the output voltage VCP, a switching circuit 4 interrupts the clamping operation by the clamping element group 2 which is large in clamp voltage and starts the clamping operation by the clamping element group 3 which is small in clamp voltage. Consequently, even if the clamp voltage varies as the source voltage VDD varies, the output voltage VCP of the charge pump 1 can be held within the proper constant range at all times.

Title: Ink quantity regulator for inking device for printer and method of operating printer with said ink quantity regulator
Inventor: BUORUFUGANGU BUIRUTOMAN
IPC: B41F31/04
Filed: 1984-07-11
Abstract: An automatic control system for a zonal ink metering device displaces ink metering elements toward a fountain roller until contact of the individual elements with the fountain roller is detected to establish absolute reference positions. Then the ink metering elements are displaced away from the fountain roller by respective predetermined amounts to obtain a desired ink profile. Once the desired ink profile is obtained, continuous printing is started. During continuous printing, the ink profile is maintained by periodically and sequentially reciprocating one individual ink metering element after another into contact with the fountain roller to reset their respective reference positions. Preferably, contact of the individual ink metering elements with the fountain roller is detected by a pair of electrical contacts in the adjusting devices for the ink metering elements. Preferably, a predetermined biasing force is applied urging the ink metering elements into contact with the fountain roller, and the adjusting mechanism applies force through the electrical contacts to displace the ink metering elements away from the fountain roller. Preferably, the ink metering elements are ink slides and electrical contact and force transmission occurs between a contact plate mounted via a rigid insulator to a substantially fixed support and the end of a threaded spindle engaging a nut fixed to the ink slide. Thus, when closure of the electrical contacts occur, the contact plate becomes grounded.

Title: Light emitting electron tube
Inventor: UETSUKI TADAO
IPC: H01J63/08
Filed: 1984-07-10
Abstract: PURPOSE:To increase light emitting efficiency by arranging a grid which controls an electron to a value suitable to excite light emitting gas. CONSTITUTION:An electron emitted from a cathode 2 is accelerated by an anode 3 which locates at a distance of L1 from the cathode 2, and decelerated by a grid 7 which locates at a distance of L2 from the anode 3. Finally, emitted electron energy is controlled to 6-10eV. Since the distance (L1+L2) is smaller than mean free path lambda of electron and the distance L3 between the anode 3 and the inner surface of a tube 1 is very large compared with the mean free path lambda, an electron emitted from a cathode 2 passes through an anode 3, and collides against a space 4 to be excited. Thereby, light emitting efficiency is increased.

Title: Method for measuring scattering light
Inventor: WYATT PHILIP J
IPC: G01N21/53
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To restrict a background effect and correctly measure a scattering light by using a sample cell which has a surface optically finished without concaves and convexes and shows a larger index of refraction than a solvent fluid including a sample. SOLUTION: A sample cell 3 is a truly cylindrical body formed of a transparent material such as glass or the like having a larger index of refraction than a solvent fluid including a sample. Each detector 2 is arranged in the circumference of the sample cell 3. A through hole 4 is formed as a channel. An outer face of the cell 3 and an inner face of the through hole 4 are optically ground and consequently have neither concaves nor convexes. A fitting instrument 5 including an optical window 6 and a hole 7 through which the sample is introduced in and out of the cell 3 is set at an opening part of each end of the through hole 4. A luminous intensity is regulated to a degree whereby a background effect is negligible on the basis of a difference of indices of refraction of the solvent fluid passing the through hole 4 and the cell 3 surrounding the through hole. Accordingly, even a considerably small amount of the sample liquid can be measured on the basis of the scattering of light.
