Title: Band-shaped magnetic recording medium and magnetic head and magnetic recording and reproducing device
Inventor: SUZUKI HIROSHI
IPC: G11B5/627
Filed: 1994-03-14
Abstract: PURPOSE:To decrease such phenomena that the signals from plural channels simultaneously generate errors by setting the joined part to a leader tape and both ends of the traveling direction of a splicing tape at a prescribed angle to a traveling direction. CONSTITUTION:The joined part of the band-shaped recording medium 1 and the leader tape 2 and both ends in the traveling direction of the splicing tape 3 for splicing the joint part are set at 45 to 85 deg. or 95 to 135 deg. angle to the traveling direction of the band-shaped recording medium 1. As a result, the diagonal mapping shapes with the traveling direction are eventually generated at the beginning and terminal ends of the band-shaped medium, unlike the shape change by the prior technique. Then, a time leg is generated between the channels and the possibility of simultaneous increasing of the error rates with the plural channels is drastically lessened at the time of passing of the shape changing parts over the gap of the head even if a conventional recording and reproducing apparatus is used.

Abstract: PURPOSE:To flower the buds of a cut cherry twig at a desired time to desired extent by placing a duct for supplying hot air and a duct for sucking hot air on the floor and the ceiling of a blooming promotion chamber, respectively, and automatically controlling the temperature and humidity in the chamber to respective prescribed levels. CONSTITUTION:A cut cherry twig having flower buds is slantly cut with a sharp edge and supported with a twig-supporting tube 4 placed in a blooming promotion chamber 1. The cut end of the twig is immersed in a water tank 3 filled with water. The temperature in the chamber is maintained to nearly constant level between 25 deg.C and 30 deg.C for 100-340hr and the humidity is kept to >=40% by operating a hot-air feeding duct 6 and a hot-air suction duct 7. In the course of the above operation, the exchange of water and draining of the twig are carried out at intervals of 5 days. About 48hr before taking the twig out of the chamber, the temperature in the chamber is gradually lowered to a temperature not lower than 5 deg.C and the bloomed cherry twig is taken out of the chamber. The blooming rate of 60-70% can be attained within 15 days in contrast with 3 months necessary for blooming under natural conditions.

Title: Measuring device of uneven thickness for transparent disc
Inventor: SHIGEMATSU KAZUO
IPC: G01B11/06
Filed: 1982-03-19
Abstract: PURPOSE:To form a device which measures the uneven thickness of a transparent disc to be used for optical discs or the like with a simple optical system with high accuracy. CONSTITUTION:Parallel luminous fluxes 1 of an He-Ne laser or the like are made incident to a disc 3 to be measured of uneven thickness roughly perpendicularly to the plane of the disc 3. The fluxes 1 transmitted through the disc 3 are made incident to a detector 7 for the positions of light spots, and the output corresponding to the angles of deviation generated by the uneven  thickness of the disc 3 is obtd. from the detector 7. More specifically, if psi<<1 where the distance from the disc 3 up to the detector 7 is defined as l and the angle of deviation of the parallel luminous fluxes as psi, the fluxes 1 on the detector 7 move by psiXl and the currents corresponding to psiXl flow in the outputs A, B of the detector 7. The value of the uneven thickness is detected from said outputs A, B. The differential signal of the outputs A, B is obtd. with a differential amplifier 10, and the AC component thereof is drawn out with a filter constituted of C and R5. The output of the filter is proportional to the rate psiXl of deviation of the parallel luminous fluxes and the quantity of the parallel luminous fluxes; therefore, the output is first divided by the output of a differential amplifier 11 proportional to the quantity of the light by a divider 12 in order to remove the influence of the fluctuations in the quantity of light and is then integrated by an integrating circuit 13, whereby the voltage proportional to the uneven thickness is obtained in an output 14.

Title: Genuineness identifying method, genuineness identifier and production thereof
Inventor: AONO TAKASHI
IPC: G06K19/06
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To make visually or mechanically and easily identifiable the genuineness by converting the incident linearly polarized light of single wavelength into an elliptically polarized light through birefringence. SOLUTION: Linearly polarized light 22 of single wavelength is made incident, that linearly polarized light 22 is converted into an elliptically polarized light 23 by birefringence and the genuineness is identified from the state of that polarization. The genuineness identifier is provided with a substrate, a reflection layer, a birefringence layer 13 and a polarization layer. An identifying person watches the genuineness identifier and confirms the color, for example, and the identifying person, who confirms the color, inclines the genuineness identifier and can identify a genuine article when the color of the genuineness identifier is changed or can confirm a forged article when the color is not changed. Since the color of the genuineness identifier is changed corresponding to the viewing angle, the genuineness can be easily identified.  Since the color is not changed in the case of the forged article based on color copy or the like, the forged article can be easily recognized. The birefringence layer 13 can be formed from a plastic film so that the mass-production can be carried out inexpensively.

Title: Washing machine
Inventor: YAMAGISHI YOSHIO
IPC: D06F39/08
Filed: 1989-02-23
Abstract: PURPOSE:To eliminate the noise generated when a valve is closed, and prevent water leakage when a drain port is closed by the valve, by a method wherein a valve is moved by a driving force of a driving mechanism until it reaches the middle of the way between the maximum open position and the shut position for the drain port, and after that it is moved by a spring member. CONSTITUTION:In case a valve 9 is moved toward the shut position, the valve is moved by a driving force of a driving mechanism 14 until it reaches the middle of a way between the maximum open position and the shut position for a drain port 7, and then it is moved by a spring 13. As a result, the force of the spring 13 becomes weak when the spring 13 begins to move the valve 9. Therefore, the impact when the valve 9 hits against the brim of the drain port 7 is so small that the noise of valve shut is diminished. Although the force of the spring is so weakened that the hitting sound does not become a problem, the spring still has an enough force to expel foreign matters when the valve 9 is struck against the drain port 7 by the spring 13. Therefore, the water leakage is prevented when the drain port 7 is closed by the valve 9.
