Title: Method for sucking liquid sample in analyzing instrument
Inventor: IMAHASHI TORU
IPC: G01N30/16
Filed: 1985-08-06
Abstract: PURPOSE:To prevent the diffusion of a cleaning liquid to an analyzing sample and the spread of the analyzing sample by sucking a gaseous phase and a small amt. of the sample of the same kind as liquid sample and further sucking the gaseous phase then sucking a prescribed amt. of the liquid sample. CONSTITUTION:The cleaning liquid 1 in a piping is fed and the specified amt. of air 2a is sucked after the analysis of the previous liquid sample. The sample 3 which is of the same kind as the liquid sample to be used for the analysis is then sucked at the min. amt. required to remove the liquid 1 and to prevent the dilution of the liquid sample to be sucked for the purpose of the analysis and further the specified amt. of the air 2b is sucked. The sample 3 of the min. amt. required for the analysis is sucked and further the air 2c is sucked. The mixing of the liquid 1 and the sample 3 is thus prevented by the air 2a and further the mixing of the sample 3 mixed with the liquid 1 and the sample 4 for analysis is prevented by the air 2a. The dilution of the sample 4 for analysis is prevented as well. Since the sample 4 is sealed by the air 2b and c, the spread thereof is suppressed.

Filed: 1991-07-12
Abstract: PURPOSE:To form always good images by mixing a toner with a carrier in a prescribed ratio and regulating a spent amount of the carrier of >=0.010% in terms of carbon. CONSTITUTION:The starting developer is a binary developer of a mixture of the toner and the carrier in the prescribed ratio, and the spent amount of the carrier is regulated to >=0.010% in terms of carbon, because fluctuation of a sensor output value is too small to prevent occurrence of image defects, such as poor image density, if the spent amount of the carrier is <0.010%. The starting developer in the prescribed mixing ratio is obtained by mixing the carrier with the toner in a mixer to force the carrier to be spent in the prescribed ratio replenishing the toner. This composition can be applied to various starting developer of the various kinds of known developers.

Accordingly, even though the tact switch S1 is opened via the closing of a switch S2, the control terminal keeps an enable state. On the other hand, when making the system power supply Vsys off, the switch S2 is opened and a switching transistor Tr1 is made off to bring again the control terminal into a disable state. To bring the system power supply Vsys into an on-state, not only for making the potential of the tact switch S1 a ground level, but also when making the potential of one of the pins of diodes D1, D2,..., Dn a ground level, the control terminal is brought into an enable state to perform the make of the system power supply Vsys.

Title: Spike tire
Inventor: OTANI NOBORU
IPC: B60C11/16
Filed: 1989-07-04
Abstract: PURPOSE:To use a tire as both an ordinary one and a spike one with a simple change over, by arraning so that a case which has a built-in standlike spike stand may be embedded on the inner side than the ground contacting surface, and a spike may be made to appear/disappear by means of the horizontal movement of the spike stand. CONSTITUTION:Right and left wires 6 are connected to a spike stand 2 provided within a case 1, and arrangement is so made that the stand 2 moves right and lift by means of wires 6. As a result, when the right wire 6 is pulled, the stand 2 pushes the bottom surface of a spike 3, and the spike 3 is projected out of a tire tread, and a tire becomes a spike tire. Conversely, when the left wire 6 is pulled and the stand 2 is moved left, the inclined surface 4 of the stand 2 becomes opposed to the bottom surface of the spike 3, and the spike 3 sinks into the inside along the inclination surface due to the weight of a car, and the tire becomes an ordinary one. Thus, the tire can be used both as a spike one and an ordinary one with a simple change over.

Title: Engine with auxiliary chamber
Inventor: KISHISHITA TAKAHARU
IPC: F02B19/08
Filed: 1990-06-30
Abstract: PURPOSE:To shorten a combustion period, decrease fuel consumption and restrain the occurrence of hydrocarbon(HC) by forming peripheral step parts respectively on the tilting side surfaces forming the upper and the lower two- stage throttling parts between communicating holes and a protruding part. CONSTITUTION:Step parts 11 and 12 in the peripheral directions, which constitute the upper and the lower two-stage throttling parts, that is, the upper side throttling parts A and the lower side throttling parts B, are formed on the tilting side surfaces 10 forming a protruding part 5 in the flowing direction between communicating holes 8 and tilting side surfaces 10 of the protruding part 5. Furthermore, the upper part tilting side surfaces 10 of the peripheral step parts are formed in nearly a horizontal form so that the inclination of the lower tilting side surfaces 22 of the protruding part 5 can be smaller than that of the upper titting side surfaces 22. In the vicinity of the upper dead center, a throttling effect of the upper side throttling parts A comes to act stronger than a throttling effect of the lower throttling parts B by constituting the upper side throttling part A and the lower side throttling part B as mentioned above. In this way, a well-conditioned air-fuel mixture can be created so that combustion can be carried out simultaneously with ignition.

Title: Liquid removing method for dry cleaner
Inventor: HAGIWARA HARUO
IPC: D06F43/08
Filed: 1989-07-07
Abstract: PURPOSE:To prevent polka dot state smudge from generating by moving slowly a solvent in clothes during a liquid removing process by a method wherein a liquid removal right before shifting to a drying process is shortened in a specified liquid removing time, and at the same time, the centrifugal acceleration for the liquid removal is specified. CONSTITUTION:When clothes, etc., of a thin fabric such as georgette are processed by a porous processing drum, using a low boiling solvent such as chlorofluorocarbon R113, etc., a liquid removing time right before shifting to a drying process is shortened to 0.5-1min which is at 1/2 or less than a normal liquid removing time. The process is performed while a centrifugal acceleration of the processing drum at the periphery is maintained in the range of 18-40g. In the case of a normal 2min liquid removal, even when a liquid removal revolution number is reduced, the solvent at parts which are in contact with ports on a porous board vaporizes and dries even during the liquid removal, therefore, polka dot state smudge cannot be prevented from generating. On the other hand, if the liquid removing time is shortened to 0.5-1min which is at 1/2 or less of a normal liquid removing time, the generation of smudge is decreased, and it is not necessary to perform rinsing again. Further, by combining with a weak revolution in the range of 18-40g centrifugal acceleration, the smudge preventive effect becomes more remarkable.

Abstract: PURPOSE:To ensure the effective use of dictionaries by using properly the dictionaries which are independent of each other for each character catagory according to each purpose of applications and therefore eliminating the use of a dictionary of large capacity that registers categories with overlap to each other. CONSTITUTION:The read input character patterns are supplied to a division candidate selecting circuit 1 of a character recognizer.

These plural selected and sorted candidate characters are supplied to an identification arithmetic circuit 3, and an identification dictionary pattern is extracted out of each identification dictionary 4. Then the discrimination contribution factor of features discriminatable among candidate characters is operated for each component element of the identification dictionary pattern. The feature having variance are applied in the order of higher discrimination contribution factors. Then a fixed number of features is secured and displayed to an answer display circuit 5. This eliminates the use of a dictionary of large capacity.
