Title: Method for improving gas permeability of layer to be sintered
Inventor: SASAKI AKIRA
IPC: C22B1/16
Filed: 1982-10-06
Abstract: PURPOSE:To improve the gas permeability of a layer to be sintered by applying vertical vibration and rolling motion to starting materials for sintering passed through a pseudo-granulating stage to improve the strength of the pseudo granules and to reduce the amount of fine grains. CONSTITUTION:Starting materials for sintering passed through a pseudo-granulating stage contain about 10-15% ungranulated fine grains having <=about 0.5mm. grain size. Vertical vibration and rolling motion are applied to the starting materials with a vibrator having about 500-1,000c.p.m. frequency and taking circular or elliptical motion in a perpendicular plane. The vibrator has a loading surface inclined slightly in the forward direction of a load, and the top of the vibrator is flat. The degree of contact of granules with one another is increased to improve the strength, and ungranulated fine grains are efficiently stuck to pseudo granules.

Title: Component for vehicle facilitating removal of dirt on metal surface caused by brake pad abrasion powder
Inventor: FURUKAWA HITOSHI
IPC: F16D65/00
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To facilitate the cleaning of dirt on a metal surface due to abrasion powder by coating photocatalyst titanium oxide on the outer surface of components for a vehicle such as a disc brake and a wheel. SOLUTION: A coating layer 12 of photocatalyst titanium oxide is formed on the outer surfaces of a caliper 1 and a support 2 of a disc brake. If the metal surface of the disc brake becomes dirty due to dispersion of abrasion powder of a brake pad, a ultraviolet ray of the sunlight is irradiated on the metal surface through a through hole 10 of an aluminum wheel 11, the coated photocatalyst titanium oxide brings about catalyst, and the dirt due to the abrasion powder of the brake pad can be resolved in a boundary surface toward the photocatalyst titanium oxide coating layer 12. This constitution can easily remove the dirt by a daily simple cleaning without using any special detergent.

Inventor: SATO MAKOTO
IPC: G03F9/00
Filed: 1992-06-09
Abstract: PURPOSE:To accurately conduct alignment of a mask and a wafer by aligning them by one aligning signal input to suppress complication of an apparatus. CONSTITUTION:A predetermined surface is aligned with a wafer mark WM on a wafer through a projecting lens 1 for projecting a pattern on a reticle R on the wafer W. In this case, a signal from detecting means for detecting an image of the mark WM formed on the predetermined surface 4a is DC/AC converted by frequency analyzing means 8a to obtain a frequency distribution in a spatial frequency region. Relative position between the surface 4a and the mark is detected by using phases from phase detecting means 8b, 8c for obtaining phases of at least two fundamental frequency peaks of the wafer mark WM by using the signal from the means 8a. Thus, a relative alignment of the reticle and the wafer can be accurately conducted.

Title: D/a converter
Inventor: KONDO HIDEO
IPC: H03M1/70
Filed: 1994-07-28
Abstract: PURPOSE:To obtain the D/A converter in which shift in an analog voltage is executed with high accuracy and simple configuration.

Title: Production of silver halide photographic material
Inventor: BABA SUSUMU
IPC: G03C1/34
Filed: 1980-12-15
Abstract: PURPOSE:To prevent the fading of the latent image by adding monocarboxy substituted phenylmercaptan to a silver halide photographic emulsion which is chemically sensitized by a gold compound. CONSTITUTION:The monocarboxy substituted phenylmercaptan compound expressed by the general formula (I)[in the formula, R is a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an acyl group, an amino group, (a) is 1 or 2]is added to silver halide at 60mg-5,000mg per mol thereof. If the settling of silver halide crystal is carried out in the presence of said compound, said compound acts as a physical ripening supressing agent to form fine particles. This prevents the fading of the latent image but lowers sensitivity. If this adapted to an emulsion which is chemically sensitized by a gold compound, it increases the sensitivity and prevents the fading of the latent image. Althrough it is added in the stage after physical repening, it has the same effect.

Title: Lead-in device for material roll through drier
Inventor: KURAUSU TAIRUAKAA
IPC: B41F23/04
Filed: 1994-07-28
Abstract: PURPOSE: To provide an arrangement which allows a printing stock web to be drawn through a dryer. CONSTITUTION: A draw-in member which grasps the tip of a printing stock web has a power transmission, e.g. a roller chain, which runs in a guide 1. Plates 3, 4 or blowing boxes which are movable vertically to the draw-in plane of the printing stock web and form closures in the guide 1 by lateral projection of their side walls are provided to prevent dirt from penetrating into this guide 1. Rollers or cylinders are provided for additional correction of lateral displacement of the printing stock web while the web is drawn in by the draw-in member.  A friction locking engagement, i.e., particularly rolling friction or adhesive friction, causes these rollers or cylinders either to exert a transverse traction on the printing stock web themselves or, in order to compensate for the lateral displacement of the printing stock web, secure the printing stock web in the correct position due to a transverse traction produced by an oppositely directed displacement of the guide 1.

Title: Dram device provided with self-refresh mode
Inventor: RYU HOON
IPC: G11C11/4074
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To improve a sense margin and to prevent a read-out malfunction by keeping a bit line precharge voltage VBL between respective halves of high/ low source voltages even when an operation voltage is returned from a low voltage VRFH to a source voltage VCC during a self-refresh cycle. SOLUTION: The operation voltage VOP of a DRAM circuit is kept to the VRFH lower than the source voltage VCC during a self-refresh mode to be returned to the VCC in the end period of the self-refresh mode. A first voltage generator 180 generates a first control voltage VINT according to a control signal PSRAS showing the self-refresh mode, and a second voltage generator 190 generates the voltage VBL of 1/2 of the first control voltage VINT. The VBL is used as the bit line precharge voltage. Since the voltage VBL is kept between VCC/2 and VRFH/2, a voltage change (sense margin of a sense amplifier) on a bit line is increased, and thus, the read-out malfunction for the data '1' is prevented.
