Abstract: PURPOSE:To provide an easily operable vacuum cooker capable of deeply impregnating the tissues and cells of a material with pickle by alternately applying negative pressure and positive pressure to the contents in a container by the transfer of a valve in a motor-driven switch valve to enlarge a difference between the pressures. CONSTITUTION:A container 15 containing a material Z and a pickle Q therein is loaded on a receiving portion of a main body 11 and the opening portion of the container 15 is closed with a closing lid 18. A motor-driven vacuum pump 12 is operated and simultaneously a switch valve 40 is switched to a position for communicating the such opening 12a of the motor-driven vacuum pump with the container 15 and for communicating the exhausting opening 12b of the motor-driven vacuum pump, thereby removing air in the container 15 to give a negative pressure. The valve 40 is subsequently switched to a position for communicating the sucking opening 12a with the atmosphere and for communicating the exhausting opening 12b with the container 15, thereby feeding the atmosphere into the container 15 with the vacuum pump 12 to give a positive pressure.

Title: Optical coupler
Inventor: OGURA SHIGETARO
IPC: G02B6/12
Filed: 1989-05-29
Abstract: PURPOSE:To improve the coupling efficiency by providing a reflecting layer on a volume type hologram and coupling light with an waveguide through a substrate. CONSTITUTION:Coherent light is coupled into the optical waveguide 11 by a reflection volume type hologram 33 placed on the opposite surface of the waveguide 11 from its light incidence surface in contact with a layer 23 which has a lower refractive index than the optical waveguide. This reflection volume type hologram consists of a transmission volume type hologram and a metallic reflecting layer 43 on it. Incident light after passing through the optical waveguide 11 and low-refractive-index layer 12 is reflected and diffracted by a grating 14 and the metallic reflecting layer 43 and part of the reflected light is captured in the optical waveguide at the incidence angle of the incident light by diffraction of degree 1 or more. The captured light has a constant propagation constant in the longitudinal direction of the optical waveguide and depends specially upon the incidence angle of the incident light and the periodicity of the grating to induce a specific optical waveguide mode, thereby coupling the light. Consequently, the optical coupler is made compact and the coupling efficiency is improved.

Title: Water-base printing ink
Inventor: KATSUYA ATSUSHI
IPC: C09D11/10
Filed: 1991-05-10
Abstract: PURPOSE:To obtain the title ink which has long pot life and gives printed matter excellent in solvent, chemical and water resistances by using a copolymer containing an acrylic ester and an organic metal chelate compound as constituents. CONSTITUTION:The title ink contains an organic metal chelate compound and a copolymer containing 3-60wt.% acrylic ester of the formula. In the vinyl monomer composition for the copolymer, an acrylic or methacrylic acid is used in an amount of 0-40wt.%. If the amount of the acid is too small the solubility of the copolymer in water will be poor; if too large the alkali and water resistances of the copolymer will be reduced. It is desirable that the weight-average molecular weight of the acrylic copolymer used be 20,000 to 70,000. The amount of the organic metal chelate compound to be used is 0.1-10wt.%. If it is below 0.1wt.%, the crosslinking effect will be poor; if above 10wt.%, plate filling will be caused by an increase in the viscosity of ink with time and a reduction in the resolubility, with the result of an adverse effect on printing.

Title: Buffer memory control circuit
Inventor: ISHII SATOSHI
IPC: G06F12/08
Filed: 1982-08-06
Abstract: PURPOSE:To exclude the undesired data and to deliver only desired data, by adding a control circuit in addition to a first-in/first-out (FIFO) memory and to discriminating the undesired data that is requested for pre-reading in the past to a main storage from the data desired at the present time point. CONSTITUTION:When a comparator 12 obtains the coincidence of comparison, a register 11 is set through a signal line 106 to fetch the data from an FIFO 10. The data fetched into the register 11 is sent to a device having a memory reading request through a route 107. Both data of the FIFO 10 and an additional information are not desired after the data is set to the register 11 and therefore taken away by an indication given from a signal of a signal line 108. When no coincidence is obtained at the comparator 12, the data is not set to the register 11. Therefore the data is invalidated and eliminated together with the additional information with an indication given from the signal of the line 108. As a result, no invalid data is sent to a device having a memory reading request.
