Title: Sliding contact material
Inventor: FUJISHIMA SUSUMU
IPC: H01R39/20
Filed: 1984-06-21
Abstract: PURPOSE:To obtain a sliding contact material having low and stable contact resistance by adding prescribed amounts of Cu, Cd and one or more among B, Si, Ge and Ti to Ag so as to control the stickiness of an Ag-Cd alloy and to improve the wear resistance. CONSTITUTION:A sliding contact material is obtd. by adding 3-12wt% Cu, 0.5- 5wt% Cd and 0.5-10wt% one or more among B, Si, Ge and Ti to Ag. When 0.01-0.5wt% Fe group element such as Fe, Ni or Co is substituted for part of said added elements, the grains can be made fine and the wear resistance is further improved. Since the sliding contact material is hardly stuck and has superior wear resistance, when the contact chips of a commutator for a small-sized motor are made of the sliding contact material, the contact chips produce very little dust due to wear during sliding along brush contacts. No noise is generated and a beneficial effect such as low and stable contact resistance is shown.

Title: Method and appratus for generating x-ray pattern
Inventor: ROBAATO EI KURUUGAA
IPC: H05G1/26
Filed: 1989-05-23
Abstract: PURPOSE: To improve contrast in the area of a low X-ray irradiation degree by detecting light in the partial area of a first pattern, generating the second pattern of the light by the different pattern by the detected light and exposing a photographic film to the second light pattern. CONSTITUTION: In X-ray irradiation, a fluorescent screen radiates the light proportionally to the amount of absorbed X-rays. The light from the screen 122 is radiated from the back surface of the screen and reaches the array of photodetectors 411. The array of the photodetectors 411 is arranged so as to receive the first pattern of the light from a second screen 122. Then, an X-ray pattern is converted into the first pattern of the light, the photographic film 125 is exposed to the first pattern of the light and the light is detected in the partial area of the first pattern. The second pattern of the light is prepared by the different pattern by the detected light and the photographic film 125 is exposed to the second pattern of the light. Thus, the contrast of the film in the area of the low irradiation degree of the X-rays is intensfied.

Title: Corrosion resisting method and method for forming magnesium substrate and mold release material layer
Inventor: OGATA SHIRO
IPC: B05D5/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To form a titania film on the surface of a base without detriment to decorative properties and thereby ensure a superb corrosion resisting performance by applying an aqueous amorphous titanium peroxide solution to the surface of a base formed of magnesium or its alloy and heating the solution at a specified temperature or below to form a transparent titania film. SOLUTION: A 0.1-2 μm thick titania film 2 is formed on the surface of a substrate 1 of a base. In this case, when the titania film 2 is thinner than 0.1 μm, a sufficient corrosion-resisting effect cannot be obtained and when the film 2 is thicker than 2 μm, the film 2 is easily peeled. In addition, magenium or an alloy containing magnesium and aluminum, zinc or the like is used as a material for the substrate 1. Further, an aqueous solution or an aqueous viscous material solution containing an amorphous titanium peroxide is applied to the surface of a magnesium alloy substrate 1 using a spray process or the like. Then the coat is thermally dried at below 200 deg.C after being dried at normal temperatures to obtain the magnesium substrate 1 containing an amorphous titania film.  Thus it is possible to form the transparent titania film 2 having outstanding adhesive properties with substrate 1 and qualitative uniformity/ surface flatness.

Title: Minimum reset time hold circuit
Inventor: MASUTAFUA ARI HAMITSUDO
IPC: G06F1/24
Filed: 1990-05-18
Abstract: PURPOSE: To reset a floppy disk controller(FDC) at an arbitrary processor speed by generating a lapse time signal driven after the writing of a first data value, generating a delay signal in response to the lapse time signal, and delaying the writing completion of a second data value until the lapse time signal reaches a prescribed value. CONSTITUTION: What time a zero value is written in a floppy disk controller(FDC) reset location 20 is judged, and a counter is started. The counter presents a first time in the floppy disk controller 20 or a time which passes after the reset operation is started. Also, the logic of an EX-10P PAL 30 relevant to the counter is combined, and the hold or delay of a processor 10 is operated until the necessary lapse time is completed. Thus, the floppy disk controller can be exactly reset at an arbitrary processor speed, and the timing group dependency of software can be removed.

Filed: 1995-04-28
Abstract: PURPOSE: To improve sealing ability of a joint between a cylinder liner and a cylinder head, in an open deck wet liner type cylinder block. CONSTITUTION: A cylinder liner 11 is pressed in a cylinder barrel 4 in the bore 3 of a cylinder block body 2 and a water jacket 6 is formed between the bore 3 and the cylinder liner 11. A plurality of bosses 14 radially extending toward a screw hole 8 for fastening a cylinder head are formed in the outer periphery of the end part on the cylinder head mounting surface 7 side of the cylinder liner 11. A plurality of bosses 14 are pressed in the bore 3 and positioned flush with a cylinder head mounting surface 7.

Title: Solenoid-operated booster
Inventor: SHIMIZU YASUO
IPC: B62D5/04
Filed: 1984-06-22
Abstract: PURPOSE:To make a power loss ever so smaller as well as to miniaturize a booster itself, by driving an electric motor and rotating an output shaft at a time when a torque detecting device installed between both input and output shafts detects the specifided torque. CONSTITUTION:When an input shaft 4 rotates in either direction of right or left, an output shaft 5 also rotates in the same direction via a arm member 27 and rubber. For a while transmitting torque form the input shaft 4 to the output shaft 5 is below the specified value, since a flection value of the said rubber is small brushed 41 and 42 are neither relatively moved nor a motor 2 drives any longer. When load in the output shaft 5 is large and the torque grows larger than the specified value, the flection value of the rubber grows large whereby these brushes 41 and 42 turns round to a slip ring 30. Therefore, an electric current flows into the motor 2 and its rotation 18 turns round in the same direction. Simultaneously with this, a relay switch closes and thereby a solenoid clutch 9 is connected. As a result, output torque of the motor 2 is transmitted to the output shaft 5, thus turning torque of the output shaft 5 increases.
