Title: Stamp stand
Inventor: NAGASAWA YASUO
IPC: B41K1/54
Filed: 1994-08-26
Abstract: PURPOSE: To open and close the lid member of a stamp stand by the single hand by bringing the lid member to a free state by releasing a lock mechanism to bring the same to a semi-open state by the elasticity of an elastomer. CONSTITUTION: A lid member 3 is held to a closed state by a lock mechanism and, at this time, the elastic base material 13 and elastic projection 14 of an elastomer 5 are elastically deformed. When the operation piece 12 of the lock mechanism 4 is pushed down on its front side, the rear part of the operation piece 12 is raised to raise the front part of the lid member 3. By this mechanism, the engagement of the pawl piece 10 and hook piece 11 of the lock mechanism 10 is released to release the lock mechanism 4. Whereupon, the lid member 3 becomes a free state to be brought to a semi-open state by the elastic force of the elastomer 5, especially, by the elastic force of the elastic projection 14. Therefore, a finger is inserted in the gap formed between a main body 2 and the lid member 3 to open the lid member 3.  When the upper surface of the front part of the lid member 3 is pushed down, the lid member can be closed.

Filed: 1984-09-27
Abstract: PURPOSE:To reduce the speed drop amount of a motor due to an impact load and to shorten the recovery time by detecting the speed drop of the motor due to the load, and transiently setting an overcompensated current reference. CONSTITUTION:An impact load detector 10 detects the impact load of a motor 1 on the basis of a motor current IM, a motor speed NM and a speed reference set by a speed setter 9 when the load is applied, and operates an integration coefficient setter 11.

Title: Analyzing method for infrared heat image
Inventor: KARAKI MITSUHIRO
IPC: G01J5/48
Filed: 1986-08-29
Abstract: PURPOSE:To accurately decide the temperature at an optional position by making the reference points of heat image data and graphic data coincident with each other and adjusting their angles, and then putting those data together. CONSTITUTION:Data on a temperature distribution measured by the infrared temperature distribution measuring instrument 13 of a measurement part 11 is inputted to a computer 15 for measurement through an interface 14. The heat image is adjusted manually to the mechanical reference line of the measuring instrument 13. Graphic information on a metallic mold drawing is inputted by an analysis part 12. The temperature distribution data and graphic form registration data are aligned with the mechanical reference line of the measuring instrument 13 and made into one data on a CRT. The heat image is distorted because of a slanting-direction image, so the graphic form based upon the graphic data displayed on the screen of the CRT is rotated in three dimensions according to an angle adjustment value to make both data meet each other. Thus, the heat image which can be discriminated only by the temperature distribution consisting of contour lines can be recognized corresponding to the drawing where the shape at the optional point is clear, so the temperature state at the optional measurement point is accurately decided.

Title: Soundproofing device for ventilating hole
Inventor: FUKUDA MITSUO
IPC: F24F7/013
Filed: 1988-08-16
Abstract: PURPOSE:To enable a sound-absorbing material to absorb noises in a wide frequency range from low frequencies to high frequencies by using a soft quality sound-absorbing material overlaid with a soft thin films for the sound-absorbing material. CONSTITUTION:When a ventilating fan 3 is run, the indoor air is drawn through a ventilating hole 2 and a weather cover 4, and discharged through an outlet 6 into the outdoor air. The noise generated by the ventilating fan 3 is absorbed by a soft quality sound-absorbing material 11 and a soft thin film 12. The soft quality material 11 effectively absorbs sounds with frequencies over 1,000Hz, whereas the soft thin film 12 markedly absorbs sounds with lower frequencies. The noise generated by a ventilating fan 3 is absorbed in a range from low frequencies to high frequencies; thus the noise in the air discharged through an outlet 6 is reduced. Noises transmitted outwardly or inwardly through the ventilating hole 2 when the ventilating fan 3 is at rest are also absorbed by the soft quality sound-absorbing material 11 and the soft thin film 12. The transmission of noises is thus prevented in a range from low frequencies to high frequencies.

Filed: 1981-12-18
Abstract: PURPOSE:To allow a selective epitaxial growth with an oxide film as a mask, by heating in a vacuum in a structure wherein polycrystalline Si is evaporated on the oxide film formed on an Si substrate. CONSTITUTION:The polycrystalline Si 1 is evaporated in thickness 250nm on the thermal oxide film 2 100nm thick formed on the Si crystalline substrate 3, and, when it is heated in a vacuum (1-5X10<-7>torr) at 1,200 deg.C for 30min, the single crystal Si approx. 150nm thick is grown. The example used with an oxide film as a mask is illustrated. In the first structure, a thermal oxide film 2' is formed on the polycrystalline Si 1, and a hole is opened on the oxide film 2' by an etching. By heating this structure in a vacuum at 1,200 deg.C for 30min, the crystallization is advanced at the part of the polycrystalline Si 1 wherein the oxide film is removed, but, at the part covered with the oxide film 2', the crystallization is not advanced, and accordingly the structure is not varied.
