Title: Reciprocating internal combustion engine with exhaust gas turbine
Inventor: SHIMONAKA TOSHIYASU
IPC: F02B37/22
Filed: 1982-06-30
Abstract: PURPOSE:To increase remarkably the rate of energy recovered by an exhaust gas turbine by throttling an exhaust gas turbine nozzle of a supercharger so that pressure in an exhaust pipe approximately equals pressure in a combustion chamber of an engine body right before an exhaust valve is opened. CONSTITUTION:A supercharger 30 drives an exhaust gas turbine 32 by exhaust gas ejected from a combustion chamber 28 to an exhaust pipe 38 in the operation of an engine body 10 and pressurizes supplied air by a blower 34 provided coaxially with this turbine 32 to supercharge said air from an air feed pipe 36 to the combustion chamber 28. In this case, by throttling a nozzle 40 of the exhaust gas turbine 32, pressure in the exhaust pipe 38 is approximately equalized to pressure in the combustion chamber 28 right before an exhaust valve 22 is opened. Thus, exhaust gas pressure introduced into the turbine 32 is raised so that rate of exhaust gas energy recovered by the turbine 32 is increased.

Title: Laminated sheet and multilayered sheet
Inventor: KOBAYASHI AKIO
IPC: B32B15/08
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a laminated sheet enhanced in preservability in a high humidity environment in a case used as a printed wiring board, reflow resistance in a solder reflow process and enhanced in the durability to a thermal shock at the time of use. SOLUTION: A base material 3 is impregnated with resin varnish and the impregnated base material is dried to form a prepare which is, in turn, molded under heating and pressure to produce a laminated sheet 18. In this case, theresin varnish of which the fracture toughness at the time of curing under heating is 2.4 MPa.m<1/2> or more is used. When a boiling solder heat resistance test for measuring the time generating delamination at the time of immersion in a solder tank is performed, a resin layer does not become fragile after boiling water absorption. Even when steam is generated in the laminated sheet 18 at the time of immersion in a solder bath, the resistance to the internal stress generated in the resin layer is achieved at the time of multilayer laminate molding. Therefore, the generation of trouble such as delamination measling within a short time can be suppressed.

Title: Device for dispensing sample and reagent
Inventor: MIYOSHI SATOSHI
IPC: G01N35/10
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To improve an analysis reliability by decreasing the output torque of the plunger drive motor of a microsyringer for dispensing a sample and a reagent as compared with a case when it is actually used for driving and obtaining the minimum drive torque of a plunger. SOLUTION: A stepping motor 2 can be switched between a bi-phase excitation or a single-phase excitation. The motor is switched to the bi-phase excitation when sucking a sample at a low speed by pulling up a plunger 3 and to the single-phase excitation when the plunger 3 is pulled down and a sample is introduced speedily. The excitation current of each phase can be switched, for example, in seven stages and a rotation from the A-phase excitation pole of the rotor to the B-phase excitation pole is performed, for example, in ten steps. When the plunger 3 is pulled up from the lowest position, the first four steps are set to the single-phase excitation, where an excitation current is gradually increased, a body 3' to be detected of the plunger 3 is detected by a photo sensor 4, and the travel is detected.  When the excitation current value on travel is equal to or less than a preset threshold, a device can be used continuously. However, when the value is equal to or more than the threshold, the device cannot be used continuously and needs to be washed.
