Abstract: PURPOSE:To enhance the clean degree and color forming property of thermal paper, by providing a thermal recording layer containing an electron donating leuco dye, an electron acceptive compound and a specific amount of a binder to one surface of base paper comprising dustless paper containing no filler CONSTITUTION:An electron donating colorless dye (leuco dye), an electron acceptive compound (coupler), a binder and an auxiliary agent are dissolved or dispersed in a solvent to prepare a coating solution for forming a thermal recording layer. In this case, it is necessary to contain 20wt% or more of the binder in the thermal recording layer. Natural pulp and a thermoplastic synthetic resin fiber comprising a binder resin or synthetic pulp having adhesiveness and flexibility to natural pulp in a molten state are subjected to a papermaking process to form dustless paper. The aforementioned coating solution is applied to one surface of the dustless paper and dried to form a thermal recording layer to obtain a thermal recording material.

IPC: H04N5/335
Filed: 1987-01-22
Abstract: PURPOSE:To improve S/N and the accuracy by executing pseudo read processing at a timing corresponding to the quantity of light without saturating an accumulative type image sensor. CONSTITUTION:Light radiated from a light source 1 reflects at the surface 2 of an original, and is converged by an optical system lens 3, and an image is formed on the accumulative type image sensor 4. A photoelectric conventing means 5 drives the sensor 4, and simultaneously quantize its output and outputs it to an external section. A light quantity detection means 6 detects at all time the light-quantity from the light source 1, and according to the result of this detection, a charge sweeping means 7 determines at which one of the plural times of reading timings preliminarily set within one time read scanning period is the pseudo read processing to be executed in order not to saturate the sensor, and outputs the timing signal of the pseudo read processing to the means 5. Accordingly, the exposure time of the sensor 4 is relatively shortened, hence it does not go to a saturated status. As a result, an output in sufficient dynamic range can be obtained, and the S/N and the accuracy can be improved.

Title: Acrylonitrile resin power with excellent whiteness for sintering
Inventor: OCHIAI TAKEHARU
IPC: B29B13/00
Filed: 1980-02-08
Abstract: PURPOSE: A resin powder giving an acrylonitrile sintered product with excellent whiteness, which comprises a copolymer of acrylonitrile with methyl methacrylate.  
     CONSTITUTION: A resin powder comprising a copolymer containing 40W98wt%, preferably 55W85wt%, acrylonitrile and the balance of methyl methacrylate. The copolymer containing less than 40wt% acrylonitrile can not give an acrylnitrile porous sintered product an excellent water absorbing property and solvent resistance, while it is exceedingly difficult for one containing more than 98wt% acrylonitrile to be sintered, and it is impossible to give practical strength. In view of the bending strength and sinterability of a sintered product, it is desirable for said copolymer to have reduced viscosity of 0.3W1.6. Since a sintered product of different porosity or particle size is obtained depending on the particle size or method of filling in a metal mold of the resin powder, in sintering, said size and filling method are selected according to application.

Title: Wireless keyboard
Inventor: OKADA HIROYASU
IPC: G06F3/02
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To shorten the data length of a key and prolong the battery life of the wireless keyboard by making a communication by using both fixed-length data format and variable-length data format together. SOLUTION: As for the (space) key, variable-length data consists of 3 bits and is shorter in data length when communicated with variable length as compared with 8 bits in case of fixed length. Therefore, when the (space) key of the wireless keyboard 2 is operated, key data 9 of the (space) key is communicated with the variable length. For the (Pause) key, the variable-length data consists of 12 bits and is shorter in data length when communication with fixed length as compared with the 8 bits of the fixed length. Therefore, when the (Pause) key of the keyboard 2 is operated, the key data 9 of the (Pause) key is communicated with the fixed length. Thus, the fixed and variable data lengths of each key are compared and the shorter format of the data is used for a communication. Consequently, the length of data to be communicated can be shortened.

Title: Exhaust device for charged-particle beam device
Inventor: TAMAI MAKOTO
IPC: H01J37/18
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To realize an exhaust device for a charged-particle beam device capable of remarkably lessening an influence of a magnetic field or heat, in the event that a molecular pump of magnetic levitation type is used as the exhaust device. SOLUTION: When a sample-changing chamber 1 is exhausted by driving a molecular pump 6, an external pressure is applied to a vibration resistant joint or metallic bellows 5 and the molecular pump 6 is several mm raised under normal conditions. As a result, a magnetism-proofing cover 11 covering the circumference of the molecular pump 6 is raised together, because it is attached to a cooling block 8. As no change occurs in a magnetic circuit formed by a magnetic field leaking from the molecular pump 6 and the magnetism- proofing cover 11, leakage of magnetic flux to the exterior is little and fluctuation can be almost eliminated. Because a cooling cover 14 is provided so as to cover the outside of the magnetism-proofing cover 11, a thermal effect on the exterior of the molecular pump exhaust device can be lessened.
