Title: Valve, sample extracting device and adding device
Inventor: SUZUKI MOTOO
IPC: G01N35/10
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To provide a valve allowing the inside to be surely washed and a sample extracting and adding device using the valve. SOLUTION: A sampling pipe 14 of a sampling valve 10 is moved in the vertical direction by a cylinder 38. When the sampling pipe 14 is moved downward, a sample intake 16 is opposed to stored samples 20 and samples can be extracted. Because the sample intake 16 is opposed to a washing water flow passage 60 when the sampling pipe 14 is moved upward, washing water is delivered from a washing water supply port 62 of a washing pipe 58 into the washing water flow passage 60. Because washing water flows from the sample intake 16 into the sampling pipe 14 and outflows from a sample discharge port 22, all at the inside of the sampling pipe 14 can be washed. In an also sample extracting device 12 using the sampling valve 10, a state that air and impurity are not mixed into samples is always maintained and samples can be stably extracted.

Title: Method and apparatus for producing sheet, and double- side protected pattern sheet
Inventor: ISAYAMA SHIGEKI
IPC: B29L7/00
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To make the peelability from a strip-like member well as compared with a sheet having a recessed pattern formed on the single surface thereof and to enhance tensile strength, in a sheet used as a liner for taking up a strip- like member having self-adhesiveness. SOLUTION: A polyethylene sheet 40 has projected parts 40A, 40B forming a lattice-like pattern, wherein a large number of ribs having a triangular shape cross each other, provided on both surfaces thereof. When this polyethylene sheet 40 is interposed as a liner when a strip-like member having self- adhesiveness is taken up, a large number of gaps are formed between the strip- like members by the projected parts 40A, 40B. Therefore, the peelability from the strip-like member having self-adhesiveness becomes well and, since the patterns on both surfaces of the polyethylene sheet 40 have a projected shape, tensile strength can be enhanced as compared with a conventional recessed pattern sheet.

Title: Prepreg and substrate
Inventor: AKACHI YOSHIAKI
IPC: B32B5/22
Filed: 1997-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a prepreg suitable for use in which magnetic characteristics are utilized and magnetic shielding is intended by a method wherein a glass cloth is impregnated with a paste slurried by kneading a ferrite powder and an epoxy resin in a solvent, which is dried. SOLUTION: A prepreg is obtained by impregnating a glass cloth with a paste in which a ferret powder and an epoxy resin are kneaded in a solvent to be slurried, and drying. Since it is thereby suitable for use in a high frequency area (100 MHz or over, especially a range of 100 MHz to 10 GHz), since the content of the ferrite powder can be increased, the prepreg suitable for a use in which magnetic characteristics are utilized or magnetic shielding is intended can be obtained, and it has a high strength. Further, when a substrate is formed by utilizing such a prepreg, bonding to a copper foil and patterning can be realized without using a nonmagnetic layer and an adhesive, and multilayer formation can be realized.

Title: Synchronizing method and system for time-division duplex transceiver
Inventor: SANDS NICHOLAS P
IPC: H04J3/06
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To provide an improved method for synchronizing the transmission and reception of a data transmission system which adopts a time-division duplex system. SOLUTION: This synchronizing processing (500) measures (502) an energy in (n) continuous frames of reception data. An alignment error estimation is calculated (504), on the bases of measured energy values of the (n) continuous frames. In another example, an improved synchronizing technique provides the capability of avoiding the frequency tone attested by a radio frequency disturbance by using an output signal from a multi-carrier modulation unit. This synchronizing technique can also establish synchronization by utilizing a leaked speech fault level. It is possible to make central transmitters synchronized to each other, by synchronizing a remote receiver of a data transmission system with the central transmitter and synchronizing a central receiver of the data transmission system with a remote transmitter.

Title: Four-cycle internal combustion engine
Inventor: MASUBUCHI MASAHIKO
IPC: F02B31/00
Filed: 1990-12-27
Abstract: PURPOSE:To secure proper combustion while decreasing a pumping loss in a four-cycle internal combustion engine. CONSTITUTION:An exhaust valve 7 is opened up to the middle term of an intake stroke. As a result, exhaust gas flows back to the inside of a combustion chamber 4 during the first half of an intake stroke, and thus a pumping loss can be decreased because negative pressure inside the combustion chamber 4 is decreased. An exhaust port 8 is formed in a herical manner, and the exhaust gas flowing back toward the combustion chamber 4 is placed in its turning motion inside the exhaust port 8. The exhaust gas continues to make turning motion around the cylinder axial line after it flows in the inside of the combustion chamber 4, and descends together with a piston 2. As a result, exhaust gas Y is collected on the top face of the piston 2 in the last half of the intake stroke, and air-mixture Z is collected in the top space of the combustion chamber 4, and the air-mixture is ignited by an ignition plug.
