Title: Vacuum cleaner
Inventor: SUNAKAWA MASARO
IPC: A47L9/00
Filed: 1991-12-24
Abstract: PURPOSE:To improve running performance by arranging a suction hose mounting section on an electric cleaner body free to rotate and providing a moving wheel which turns interlocking the suction hose mounting section. CONSTITUTION:A suction hose mounting section 8 which is mounted beneath a body case 5 and has moving wheels 7a and 7b rotates freely in the direction of the arrow A. As a result, for example, when jerked suddenly in the direction of the arrow C right sideways at 90 deg. by a suction hose 2, the moving wheels 7a and 7b can be moved in linkage in the direction of the arrow C with the rotation of the suction hose mounting section 8 following the guidance of the suction hose 2. In addition, a wheel 6a rotates in the direction of the arrow D and a wheel 6b rotates in the direction of the arrow E to allow the turning of an electric cleaner body 1 easily without tipping it thereby assuring excellent running performance.

By said process, a motor 3 is rotated by the driving means 4 in 50% on-time and 50% off-time and a wound-up state at 60% pulse- duty ratio is indicated in the indicating means 16. In a judging means 9, an L-signal for a time sent from a pulse interval-measuring means 8 longer than a fixed time, or an H-signal for a time shorter than the fixed time, is subjected to feedback to the ensuring means 10. In the ensuring means 10, the pulse-duty ratio is gradually increased from 60% to 100% for the L-signal and the pulse- duty ratio is gradually increased for varying to the H-signal.

IPC: C08F2/44
Filed: 1989-12-29
Abstract: PURPOSE:To improve color tones by dispersing a monomer compsn. consisting of a polymerizable monomer soln. or dispersion, which is prepd. by dissolving or dispersing dyes or pigments treated by a mass polymn. method into a polymerizable monomer, and a polymn. initiator into an aq. dispersion medium and subjecting the mixture to a suspeision polymn. CONSTITUTION:The monomer compsn. is prepd. by mixing the polymerizable monomer soln. or dispersion, which is prepd. by treating the dyes or pigments having chromatic colors by the mass polymn. method into the polymerizable monomer, and the polymn. initiator. This compsn. is dispersed into the aq. dispersion medium and the medium is subjected to the suspension polymn.

Title: Multicolor image recorder
Inventor: YAJIMA TOSHIAKI
IPC: B41J2/455
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To contrive the way to adjust dislocation of printing heads in a main scan direction and in an auxiliary scan direction and also adjust dislocation of the printing heads with a memory unit of a low capacity, without the use of a special detector or a particular control, in a tandem multicolor image recorder. SOLUTION: A correction control part 36 creates video data to be driven into an auxiliary scan direction, then adjusts dislocation in the position of a printing head in a main scan direction by causing a printing head to perform a light exposure in n-split sections in a main scan direction, and adjusts dislocation in the printing position of the printing head in the auxiliary scan direction by outputting a horizontal synchronous signal to a print control part through a video I/F control part 34. Thus it is possible to adjust not only dislocation in the main scan direction and the auxiliary scan direction but also oblique dislocation in the printing position of the printing head. Further, dislocation in the printing position of the printing head can be prevented from occurring with the help of a storage means a low memory capacity by performing an address control when accessing memory.

Title: Electroplating method using gas diffusion electrode
Inventor: KOGA HIDEHARU
IPC: C25D7/06
Filed: 1993-12-17
Abstract: PURPOSE:To eliminate the leakage of the gaseous hydrogen supplied to gas diffusion electrodes by using a gaseous mixture composed of gaseous hydrogen contg. gaseous hydrogen of a specific concn. and an inert gas as the gas to be supplied to the gas diffusion electrodes. CONSTITUTION:The gaseous mixture contg. the gaseous hydrogen of a concn. of 0.1 to 10% is used as the gas to be blown to the gas diffusion layers 3a side of the gas diffusion electrodes 3. Hydrogen ions are diffused into the plating liquid in a plating tank 2 by the gaseous hydrogen in the gaseous mixture blown to the gas diffusion electrodes 3 and electroplating is applied on the surface of a metallic strip 1 moving continuously in the plating tank 2. At that time, the anode reaction of the electroplating is a hydrogen oxidation reaction and, therefore, the production of gaseous chlorine and gaseous oxygen in the gas diffusion electrodes 3 as anodes does not arise. Further, the diffusion rate of the hydrogen into the plating liquid is controlled by regulating the hydrogen partial pressure in the gas. As a result, the electroplating films are safely and efficiently formed on the metallic strip.

IPC: E05C1/06
Filed: 1989-12-27
Abstract: PURPOSE:To improve the operation performance even if a handle is set in any direction by forming a cylindrical projection part in a recessed part at a part of the installation fitting of the handle and installing the handle in turnable manner by inserting the handle basic part from the cut part of a rotary body. CONSTITUTION:A handle 16 is installed on a longitudinal rail 7 of a joint part between one door body 1 and the other door body 2. A cylindrical bulged part 20 having a recessed part 21 at a part is formed on one center surface of an installation fitting 17, and fixed on the longitudinal rail 7. A rotary body 28 is formed from a cylindrical part 32, etc., fitted with the circular hole 19 of the installation fitting 17, and the basic part of the handle 16 is inserted from a cut part 34, and installed in tunable manner. In the state where the handle 16 is set in the longitudinal direction, the basic part 16a contacts the bulging part 20 of the installation fitting 17, and the handle 6 is erected, and a sufficient gap L2 for inserting fingers between the longitudinal rail 7 is formed. When the handle 16 is set transversely, the basic part 16a contacts the recessed part 21 of the installation fitting 17 by the force of a coil spring 36, and the handle 16 approaches the door body side, and the projection width L1 reduces. Accordingly, the operation performance of the handle is improved, and the gap between the door bodies in the case when the folded door is opened can be reduced.

Title: Image-forming device
Inventor: KURIMOTO AKIRA
IPC: H04N1/00
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide an image-forming device in which deterioration in image quality such as a shadow is avoided, without increase in deterioration of the image quality. SOLUTION: Since a light from an optical path L1 to an optical path L2 is shut by a lead-ledge 201, no light from a light source reaches a range from a position P1 to a position P2. A light from an optical path L2 to an optical path L3 passes through an end 203a of a platen glass 203. As a result, since no edge erasure processing is conducted, when an original A exists in a range from the position P1 to a position P3, a shadow is recorded on paper. Thus, a reference position RP which is a reference, when the image of the original A is read, is set to a position apart from an edge 203a from the position P3. Thus, the effects of a luminous quality change due to the lead-ledge 201 and the end 203a are not received.

Abstract: PROBLEM TO BE SOLVED: To provide a probe for scanning probe microscope which can be inserted into the very narrow groove, etc., of a semiconductor sample and can detect an interactive force between the probe and the internal surface of the sample, and a method for detecting the force that acts on the probe. SOLUTION: A probe for scanning probe microscope is provided with a supporting section 2, a probe section 4, and a detecting section 3 which is positioned between the supporting section 2 and the probe section 4 and detects an interactive force between the probe section 4 and a sample, with the detecting section 3 and the probe section 4 being substantially formed on the same axis. Since the detecting section 3 and the probe section 4 are formed on the same axis, the spatial restriction to the probe section 4 becomes smaller and the section 4 can be inserted into the very narrow groove, etc., of the sample.  When the probe is excited to make torsional resonant motions and the change of the torsionally vibrating state of the probe which occurs when a force acts on the probe section 4 is detected, the interactive force between he section 4 and the sample can be detected with high sensitivity.
