Title: A/d conversion circuit
Inventor: ONO MAKOTO
IPC: H03M1/20
Filed: 1988-08-25
Abstract: PURPOSE:To realize wide dynamic range A/D conversion at a high speed by using the A/D converter of small number of bits, inputting sampled data in a memory and taking a difference with a signal to be sampled. CONSTITUTION:An input analogue signal Vn is inputted to an adder 4 and is inputted to the eight bits-A/D converter 1 with small number of bits. A digital signal sampled in the A/D converter 1 is inputted to the memory 3 through the adder 4. The memory 3 executes storage at every sampling (however, an initial value is stored at first). When an input analogue signal Vn+1 is inputted, the digital signal Vn stored in the memory 3 is transmitted to the D/A converter 2 of eight bits, is converted into the analogue signal Vn and is inputted to the adder 4. Here, subtraction with the input analogue signal Vn+1 is executed and the A/D converter 1 A/D converts only the difference. After A/D conversion, addition with the digital signal Vn is executed again, whereby the digital signal Vn+1 required is outputted.

Title: Control system for station data memory
Inventor: KINOSHITA KENJI
IPC: G06F13/40
Filed: 1983-11-11
Abstract: PURPOSE:To improve the system processing capacity as well as the economical properties by using a data memory bus in addition to a processor bus for connection of station data memories fewer than main processors. CONSTITUTION:A local processor LP 11 is connected to a main processor MP 25 via a processor bus 13 containing a processor bus controller PBC 12. A station data memory DM 24 is provided independently of the bus 13 and connected to the MP 25 via data memory bus 23 having an input/output bus function. The memory DM 24 fetches the signals of the MP 25 on the bus 23 like an input/output device set to an input/output bus and therefore performs the connection and the transfer of information. In such a way, the bus 23 is provided in addition to the bus 13 with addition of a device selecting means within the DM 24 itself. Furthermore station data memories fewer than the main processors are added for connection. This improves the system performance and economical properties.

Title: Scanning optical device
Inventor: FUJITA TORU
IPC: G02B26/12
Filed: 1986-09-09
Abstract: PURPOSE:To improve correction of the curvature of image plane and the ftheta characteristics by constituting a device so that a surface to be scanned and an approximately arcuate image forming point locus cross each other in the peripheral part of the surface to be scanned. CONSTITUTION:The laser beam emitted from a semiconductor laser 21 is converted to parallel rays of light by a collimator lens 22 an is condensed by an image forming lens 23 so that the image of a recording body 27 as the surface to be scanned, and the image of the light is linearly formed on the deflecting face of a rotating polygonal mirror 25 by a one-direction condenser lens 24 which has the image forming capability only in the direction vertical to the deflecting plane of the rotating polygonal mirror 25. The laser beam is reflected and deflected on the deflecting face of the rotating polygonal mirror 25 rotated at a uniform speed in the direction of an arrow and is scanned from the point Q to the point Q' on the recording body 27 as the surface to be scanned in every deflection. At this time, the ftheta characteristic is electrically corrected. Since the deflecting plane of the rotating polygonal mirror 25 and the recording body 27 as the surface to be scanned have conjugate relations by a plano-convex cylindrical lens 26, the image of the laser beam is formed at the same point on the recording body 27 even if the deflecting plane of the rotating polygonal mirror 25 is inclined, and surface inclination of the deflecting face is corrected.

Title: Acceleration of anaerobic digestion by high-frequency wave
Inventor: SUZUKI AKIRA
IPC: C02F11/04
Filed: 1983-11-11
Abstract: PURPOSE:To enhance activity of microorganisms themselves, accelerate an anaerobic digestion reaction and thereby increase the quantity of a gas generated to 3-4 times of a conventional value, by irradiating a disgested sludge with high-frequency waves with a frequency of 1-50MHz, when anaerobically digesting an organic waste material. CONSTITUTION:A digested sludge is drawn out from an anaerobic digesting tank 1, and is returned into the tank 1 through a high-frequency wave irradiator 2, in which the digested sludge is irradiated with high-frequency waves with a frequency of 1-50MHz to markedly enhance the activity of anaerobic bacteria in the digested sludge, thereby increasing the quantity of gases (b) generated and enabling to perform a high-load operation. In this method, the digested sludge drawn out from the digesting tank 1 is irradiated with the high-frequency waves continuously, discontinuously or pulsewise, while anaerobically digesting the organic waste material (a). In the case of irradiating the sludge with the high-frequency waves pulsewise, for example, 1cc of the sludge is irradiated with the waves for 0.01-several sec per 1hr, and this operation is repeated.

Title: Connector with low insertion force
Inventor: SUZUKI SATOSHI
IPC: H01R24/00
Filed: 1990-08-09
Abstract: PURPOSE:To lower the insertion force at the time a male housing is inserted into a female housing to improve the workability of wire harness assembly by carrying out the insertion in the way that a displacement part of a plate spring-like tongue of the tip of a male terminal is attached by an attachment piece to narrow the male terminal width and under this condition the male terminal is inserted into the terminal housing of a female terminal. CONSTITUTION:A displacement part 31 of a plate spring-like tongue 28 in the tip side of a male terminal 27 is so made as to be attached by an attachment piece 29 in the way of freely detached by displacement. When this displacement part 31 is moved to the attachment piece 29, attached by the attachment piece 29, and a male housing 4 is inserted into a female housing 2, the plate spring- like tongue 28 is inserted into a terminal housing 22 with a low inserting force while having an idle space. Just before the completion of the insertion of the male housing 4 into the female housing 2, an extrusion 23 pushes the attachment piece 29 to release the attachment of the displacement part 31 by the attachment piece 29. Consequently, a hooking part 32 is parted from the attachment piece 29 and the displacement part 31 is moved and contacts with the inside of the terminal housing 22 with forcing force.

SOLUTION: In a stud 1 having a spherical surface bearing, a race 3 is composed of a first member 3a and a second member 3b so that a sphere receiving part 301 can separate in the direction of the axis C. Contact planes 5 and 6 to contact with each other almost in parallel to the direction of the axis C, are arranged on the first and the second members 3a and 3b.

When the stud 1 having this spherical surface bearing is manufactured, a sphere 2a is sandwiched by the separately molded first and second members 3a and 3b, and the first and the second members 3a and 3b are engaged with each other by the screw parts.  At this time, the positional relationship between the first and the second members 3a and 3b is optionally set by adjusting a screwing-in quantity of the screw parts, and a clearance between sphere receiving parts 301 of the race 3 and the sphere 2a is properly adjusted. The first and the second members 3a and 3b are positionally adjusted by a pin 4, and the clearance is made unchangeable.

Abstract: PURPOSE:To improve the water resistance and to make the titled composition usable for a bonding material, etc., by incorporating Sb2O3 into the composition of low-temp. softening glass consisting essentially of V2O5-P2O5 which is weakly resistant to water. CONSTITUTION:About <=15wt% Sb2O3 is added to the low-temp. softening glass consisting, by weight, of about 50-70% V2O5, about 16-24% P2O5 and about 1-25% of at least one kind selected from Na2O, K2O, Rb2O, Cs2O, TeO2 and Tl2O to obtain the desired glass composition. The glass has excellent water resistance and has 80-110X10<-7> thermal expansion coefficient and 358-400 deg.C softening point. Accordingly, the expansion is comparatively low and the m.p. is low. Consequently, the glass is appropriately used as bonding glass for the material having low heat resistance and comparatively low expansion, wherein the conventional PbO low-temp. softening glass is difficult to use.
