Title: Two-cycle engine
Inventor: FUJIMOTO KAN
IPC: F02B75/02
Filed: 1981-02-23
Abstract: PURPOSE:To improve the efficiency of fuel consumption by constricting a pair of scavenging air passages on both sides of a piston toward a scavenging port, thereby increasing the velocity at which the stream of scavenging air flows into the cylinder through the scavenging port. CONSTITUTION:A pair of scavenging air passages 13 provided on both sides of a piston 14 are constricted toward a scavenging port 15 so that the horizontal cross sectional area S1 of the scavenging air passage 13 facing the lower end 15a of the scavenging port 15 is less than 60% of the horizontal cross sectional area S2 of the scavenging air passage 13 facing the upper end 16a of the scavenging port 16 when the piston 14 is at BDC. This increases the velocity at which the scavenging air A flow into the cylinder 12 through the scavenging port 15. As a result the incoming scavenging air A flows, smoothly guided, along the inside 12a of the cylinder facing the exhaust port 17. Thus the scavenging air is prevented from flowing into the exhaust port 17 as indicated by arrow B, thus so much improving the fuel consumption efficiency.

Title: Automatic analyzing device and method for processing result of analysis used for the same
Inventor: NAKAZATO TOSHIAKI
IPC: G01N35/00
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To enable countermeasures against errors with little load on operators by previously storing the settings of output modes according to output means for every error code and outputting the results of analysis from an output means according to the settings of modes. SOLUTION: Priority is allotted to error contents. When a plurality of error determinations are, for example, performed in one item of analysis, only the error code of error contents with the highest priority is outputted. At this time, in the priority of error contents, error contents such as sample shortage in which it is impossible to execute analyzing work or to obtain analysis data are given the highest priority, and error contents such as errors in a calibration curve in which it is possible to execute analyzing work and to obtain analysis data but with poor reliability are given the next highest priority.  Since it is possible to determine afterward processing speedily, if error contents except errors in analysis such as panic errors in not reaching low values/exceeding high values in alarming clinical anomalous values are given the lowest priority, this method is advantageous in practicality.

Abstract: PURPOSE:To cool the inner surface side of a molded item in a short time and consequently obtain the normal molded item even when the wall of the molded item is thick or core pins are slender by a method wherein the inlet part of a small hole made on the fixed core pin is connected to a compressed air supply source and the outlet part of a small hole made on the movable core pin is throttled. CONSTITUTION:When molds are open at the predetermined opening angle not wider than full opening after a molded item is cooled in the molds for the certain period of time, the abutting part 2' of a fixed core pin 2 and the abutting part 6' of a movable core pin 6 are separated from each other so as to produce a distance between the fixed core pin 2 and the movable core pin 6. When compressed air is kept on being supplied in a flow path circuit under the state just mentioned above, the compressed air flows from the end of a small hole 14 formed in the fixed core pin 2 in the interior of a molded item 19. In addition, since the compressed air flowed in the molded item 19 is throttled by a small hole 16 formed in the movable core pin 6, the pressure of the compressed air becomes high, resulting in pressing the inner surface side of the molded item 19 with the elevated air pressure and consequently preventing the molded item 19 from swelling and it is molded into the normal molded item 19. After the hardening of the molded item 19, the molds are fully opened so as to remove the molded item 19 with an ejector pin 7.

IPC: B60S1/08
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a switching arrangement for wipers of a vehicle generating less operational noise and having high formation for a practical use. SOLUTION: When a wiper contact 16 opens between an earth contact WE and a high speed contact +W2 and between the earth contact WE and a low speed contact +W1, an INT contact 17 closes between an auxiliary earth contact IE and an auxiliary high speed contact +I2 and conducts between the earth contact WE and the high speed contact +W2. Consequently, opening and closing between the earth contact WE and a high speed contact +W2 and opening and closing between the earth contact WE and a low speed contact +W1 are synchronizedly performed, then operational noise of a relay switch becomes less times. Since it is no longer necessary let the high speed contact +W2 come close to the low speed contact +W1, formation of an operational distance and an electrical gap of an operational lever 12 becomes less.
