Title: Production of highly active metallic fine particle
Inventor: SUDO KAZUO
IPC: B01J13/00
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To obtain a highly active metallic fine particle without using any special chemical and device by controlling a metal ion soln. to a specified tamp., reducting a metal ion and keeping a colloidal state. SOLUTION: A reducing agent is added to a metal ion soln. to reduce a metal ion while controlling temp. and pH, hence a metallic fine particle is deposited in the soln., and a highly active metallic fine particle is produced. The soln. is heated from 20 to 80 deg.C in the reaction, the pH is kept at 4.0-11, the metal ion is reduced independent of a surfactant, and the colloidal state is kept. Consequently, an obtained metal colloid is used as a metal cluster, and a catalytic activity much higher than that of a bulk catalyst is obtained.

Then, the laser light flux is made incident on an automatic collimator optical system 350 and observed by a rough alignment monitor 381 and a fine adjustment monitor 382. At first, while observing the light flux by the rough alignment monitor 381, the posture of a laser pen 10 or a fixed prism 15, for example, is changed and the inclination of the optical axis in the laser light flux from the laser diode 11 is roughly aligned. Next, while observing the light flux by the fine alignment monitor 382, the posture of the laser pen 10 or fixed prism 15 is further changed and the inclination of the optical axis in the laser light flux is aligned fine. Thus, the inclination of the optical axis to the guide rail can be easily and exactly adjusted.

IPC: F01C21/08
Filed: 1982-12-24
Abstract: PURPOSE:To raise the efficiency of a compressor at the time of its low-speed operation and to prevent burn-out of a rotor at the time of high-speed operation, by constituting the rotor of a vane type rotary compressor used for an air conditioner by a ceramics material. CONSTITUTION:A rotor 5 made of a ceramics material is supported in a freely rotatable manner by means of bearings 4 fitted in a rear plate 1 and a front plate 2. A plurality of grooves 6 are formed in the outer peripheral surface of the rotor 5 in the radial direction of the same, and vanes 7 are fitted in these grooves 6 in a slidable manner.

Title: Power supply interruption notice system of switchboard
Inventor: YOSHIMURA SHIYUUJI
IPC: H04M3/60
Filed: 1983-11-29
Abstract: PURPOSE:To discriminate power interruption and a fault of a switchboard by a central controller depending on the presence of registration when the switchboard gives no response to a request from a switchboard controller by registering a power supply interruption notice signal from the switchboard to the central controller. CONSTITUTION:A key is provided to each switchboard SWBD so as to give a notice of power supply-off of the switchboard to the switchboard controller PSC and the central controller CC. This notice is received by the switchboard controller PSC as a response to a response request signal KRQ from the switchboard controller PSC and informed to the central controller CC. The central controller CC registers the power supply off notice and when the corresponding switchboard SWBD gives no response to the response request signal KRQ, the switchboard is handled as power supply OFF. On the other hand, when no power supply-off notice is given and the switchboard SWBD gives no response, the switchboard controller PSC informs the switchboard as a faulty board to the central controller CC, which performs fault processing.

Title: Method for detecting fatigue and damage in structural member
Inventor: FUJIMOTO YUKIO
IPC: G01M99/00
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To detect indirectly cracks and damages in a structural member by mounting a sacrifice material while in a potential difference method an electrode is connected directly to the structural member to detect the generation of the cracks and the degree of fatigue and damage of the structure, so that the sensitivity of detecting the potential difference is degraded and current cannot be practically directly sent to the structural member. SOLUTION: A sacrifice material 1 producing fatigue and damage earlier than a structural member is mounted to a position of the structural member constituting a structure. The sacrifice material 1 is previously formed with a crack 5 having a predetermined length. A change in the length of the crack is measured by a change in a potential difference between two points sandwiching the crack 5 to forecast the fatigue and damage of the structural member, so that the length of the crack can be measured even in a place where the sacrifice material cannot be directly viewed, and measured with higher accuracy than that in the visible place to improve the presumption accuracy concerning the degree of fatigue and damage of the structural member.

Filed: 1988-09-12
Abstract: PURPOSE:To improve cornering performance as well as running performance by providing a control means which energizes a front frame around a connecting shaft at its standing-up position. CONSTITUTION:A front wheel 3 is suspended from a front frame 1 after a round tire 3a has been fixed onto the frame via an inverted by front fork 2, and a rear wheel 6 which is acting as a driving wheel and is equipped with a wide flat tire 6a via a rear fork 5, is suspended from a rear frame 4. The front frame 1 and the rear frame 4 are connected rotatably with each other around a shaft 8 via a connecting shaft 8. A control means 21 energizes a rotating section 18 around the connecting shaft 8 in such a way that the front frame 1 which is rotatable around the rotating shaft 8 integrally with the rotating section 18, is forwarded to its standing-up position. This constitution makes the front frame keep standing vertically at all times at the time of running straight ahead so that straight ahead running performance can be improved. At the time of cornering, the rear wheel which is not banked, is pressed on the ground, its gripping force is thereby improved so that speedier cornering can be performed.

Abstract: PURPOSE:To enable to more integrate a semiconductor integrated circuit by a method wherein, in the semiconductor integrated circuit being provided with plural semiconductor regions, a high-resistance region, by which the cross sectional area of the semiconductor region roughly intersecting orthogonally with the current of electric current of the semiconductor region is partially reduced, is provided at each of the semiconductor regions.

By this region 10, the cross sectional area of the region 8 nearly intersecting orthogonally with the current of electric current of the region 8 is partially reduced and the resistance value of the element 11 is made to increase. As a result, in a semiconductor integrated circuit being provided with plural regions 8, each having the same pattern for constituting the plural elements 11, the elements 11 having various resistance values can be constituted by arbitrarily providing the region 10 or by arbitrarily providing the configuration thereof. Accordingly, the elements 11 having high-resistance values can be easily constituted by serially connecting the region 8 in a plural number, thereby enabling to more integrate the semiconductor integrated circuit.

Filed: 1991-09-09
Abstract: PURPOSE:To decrease the area or electrode required for obtaining a necessary capacitance by composing a lower electrode of a metal layer, e.g. single crystal Al, superposed by a high melting point metal while composing a dielectric of a high melting point metal oxide thereby increasing capacitance per unit area. CONSTITUTION:Single crystal Al, is employed in the formation of a lower electrode 2 which is coated with a thin film 3 of amorphous Mo having high melting point. Thickness of the thin Mo film 3 depends on the temperature for forming an interlayer insulation film 4 and crystallization is accelerated as the temperature rises thus forming micro-irregularities. Ta2O5 is employed in the formation of dielectric 1 in order to suppress mutual diffusion of Al and Ta. Single crystal Al film or polycrystalline Al film is employed in the formation of an upper electrode 2'. In order to suppress mutual diffusion of the upper electrode 2' and the dielectric 1, a TiN film 8 is deposited as a barrier metal. This constitution allows employment of thin Ta2O5 film as a single layer, reduces leak current, and increases capacitance per unit area.
