Patent JP-H10146061-A (JP)
Title: Inverter and solar generation system
Inventor: OKA SEIJI
IPC: G05F1/67
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To provide an inverter reducing generation of harmonics by suppressing distortion of output current, and a solar generation system using the same. SOLUTION: There are provided first and second parallel resonance DC link circuits 5, 6 for setting an input voltage of an inverter circuit 1 to zero. The first parallel resonance DC link circuit 5 sets an output voltage to zero voltage after a delay time has passed from the rise of the PWM pulse. The second parallel resonance DC link circuit 6 sets the output voltage to zero voltage after a delay time has passed from the falling time of the PWM pulse, and changes the delay time depending on the pulse duration of the PWM pulse. As a result, even when the pulse duration of the PWM pulse has become narrow, an output can be obtained in synchronism with the resonance operation.

That is, the memory of one wait cycle and the memory of zero wait cycle are alternately accessed to constitute the memory of 0.5 wait cycles. Thus, the inexpensive memory circuit of a short wait cycle is obtained.

Title: Multiple signal processor
Inventor: SATO KOICHI
IPC: H04N7/01
Filed: 1990-11-09
Abstract: PURPOSE:To improve the picture of a moving picture with a simple constitution by using a transmission path and performing transfer while taking a high frequency component in the time direction as small and transferring oblique high- frequency component of the low-frequency component in the time direction instead at the time of the picture which moves slowly. CONSTITUTION:A multiple signal selection circuit 104 decides the vertical high frequency component of the time direction high-frequency component. When the level of this component is high, the output of a multiple signal generation circuit 315 is selected by a selector 103. When the level is low, the oblique high-frequency component of a multiple signal generation circuit 102 is selected by the selector 103. The output of the selector 103 is inputted to an adder 316 to be added to the time direction low-frequency component. Further, it is added to the time direction low-frequency component in an adder 317 and inputted to a mixing circuit 308 as a signal for moving image mode. Thus, the oblique high-frequency component is transferred as the multiple signal at the time of the slow-moving picture.

Title: Superconducting magnetically shielding body
Inventor: KOJIMA MASAHIRO
IPC: H05K9/00
Filed: 1991-09-04
Abstract: PURPOSE:To make the size of a superconducting magnetically shielding body large-sized and to make the total weight of the shielding body lightweight by a method wherein superconductor pieces are bonded partially in a superconducting manner and remaining parts mutually form spaces in a noncontact manner so as to display a prescribed shape. CONSTITUTION:Many rod-shaped superconductors 1 whose cross section is square are first manufactured. The rod-shaped superconductors 1 may be formed by cutting a previously manufactured sheetlike superconductor to prescribed sizes. The length of each rod is decided arbitrarily. The obtained square rod- shaped superconductors are bonded 2 sequentially in a superconducting manner and piled up to be a grid shape. They are baked. Thereby, all the rods are coupled in a superconducting manner. Since a bonded-type superconducting magnetically shielding body which is manufactured in this manner is coupled superconductively as a whole, a superconducting current which offsets an external magnetic field flows continuously even when the external magnetic field is applied from any direction, and it is possible to prevent the external magnetic field from creeping into a shielding container.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject TiO2 powder extremely low in cohesiveness, high in dispersibility in oily components such as a vehicle and useful as a pigment excellent in handleability by selecting TiO2 powder subjected to a hydrophobic treatment and having a specific masking rate. SOLUTION: TiO2 powder subjected to a hydrophobic treatment, having a masking rate of >=50% in a non-aqueous medium (e.g. liquid paraffin) and preferably having a silicone oil-absorbing amount of <=30cc/100g, is selected. The TiO2 powder is obtained by treating an aqueous slurry containing TiO2 powder with a silane coupling agent preferably comprising an alkoxysilane (e.g. methyltrimethoxysilane) at a pH of 4-9, preferably 6-8, and subsequently spray-drying the treated TiO2 powder. Prior to the treatment with the silane coupling agent, a metal (hydr)oxide (e.g. alumina) is deposited to the surfaces of the TiO2 particles.

Title: Process cartridge and image forming device
Inventor: HOSHI NOBUHARU
IPC: G03G21/16
Filed: 1994-12-07
Abstract: PURPOSE: To easily and surely load/unload a process cartridge in a device main body by setting a force for pressing the shutter means of the process cartridge in its closing direction to a particular size. CONSTITUTION: A twisting coil spring 17c is attached to the rotary shaft part of a shutter arm part 17a and this presses a shutter member 17b always in its closing direction. When an open/close cover 18 is opened, the thrust pressure applied by cartridge pressing parts 20a and 20b is released. By means of the energizing force of the spring 17c, the shutter member 17b pushes a shutter receiving base 19 and by means of its reactive force, the loading direction front side of the process cartridge B is rotated and moved with a projection 21 as a fulcrum. Thus, the process cartridge B is raised from its normal loading position to its second position and a guide projection part 16b is detached upward from the U groove 16c of a guide part 16a. In this manner, the pressing force of the spring 17c is set.

Title: Paper conveyance device
Inventor: KANDA SATOSHI
IPC: B65H5/36
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce slide sound of a flexible sheet and paper because a paper guide member is the flexible sheet and a tip thereof is like saw teeth to weaken pressure contact force of the tip of the flexible sheet and paper. SOLUTION: Paper which is conveyed in the direction of B from an intermediate tray is provided with downward curl in many cases, and a flexible sheet 10 is bent in the right direction to prevent folding and jam. Accordingly, the paper which is conveyed in the direction of A from a paper supply tray detours a tip of the flexible sheet 10 and enters a pair of conveyance rollers 3, 5. For this reason, the paper is conveyed while it slides the tip of the flexible sheet 10, and the flexible sheet 10 vibrates to generate a large sound, causing a noise in some case. The tip 10a of the flexible sheet 10 attached to a guide plate 6 is substantially like saw teeth so that a contact area of the tip of the flexible sheet 10 and paper is reduced and the rigidity of the tip thereof is weakened to reduce slide sound.

Then graphic arithmetic is carried out for an OR or AND between patterns and the connecting relationship are recognized among elements and wirings contained in the mask pattern data. An original element and a node number are added to each of graphic data forming an element and a wiring. Then a pattern of a power supply wiring containing an element or a node number to which the geometric design rule verification is desired is extracted. The geometric design rule verification is carried out between said extracted pattern and a diffusion layer pattern excluding a power source. In this case, an error if detected is displayed.
