Title: Optical information recording and erasing device
Inventor: ASO SHINICHI
IPC: G11B7/0055
Filed: 1986-07-02
Abstract: PURPOSE:To surely completely erase information with a low power and less thermal damage by arranging two light beams symmetrically with respect to the center line of a recording track and simultaneously projecting them. CONSTITUTION:Elliptic erasing light spots a1 and a2 whose lengthwise direction coincides with the direction of a recording track 1 are arranged symmetrically with respect to the center line of the recording track 1 and are simultaneously projected. At this time, elliptic light spots a1 and a2 are projected with the same shape and the same power. Since at intensity of light in the recording track is approximately uniform but the intensity of light is quickly reduced on the outside of the recording track 1, the total power obtained by integration, namely, the power of a laser is reduced. Though a maximum temperature of a recording film is higher than the temperature of crystallization of recording materials and the recording film is crystallized by gradual cooling due to slow reduction of the intensity of light of elliptic light spots a1 and a2 to erase information, information is surely and completely erased if the temperature of the whole of the recording track in the breadthwise direction is raised to the melting point of the recording film.

Title: Cold rolled bright steel sheet
Inventor: KOBAYASHI YOSHIKI
IPC: B21B1/22
Filed: 1980-11-04
Abstract: PURPOSE: To manufacture a cold rolled bright steel sheet having a prescribed roughness in its front and back surfaces, with a high yield, almost having no need for a buffing work, by permitting a rolling roll to apply a temper rolling process to the steel sheet.  
     CONSTITUTION: The titled steel sheet is especialy suitale for use of a stationary binder, a stove reflector, etc., and has a surface roughness, ≤0.05μ Ra on one side and ≤0.10μ Ra on another side. The work rolls 1, 2 and backup rolls 3, 4 of a concerned rolling mill are driven to rotate respectively in a direction shown by an arrowed mark. A foreign matter, adhering to the surface of the work roll 1 is removed by a brush 5. A temper rolling mill oil supplied from a nozzle 6 keeps the surface of the work roll 2 clean; the temper rolling mill oil entering the feed-in side along with the rotating surface of the backup roll 4 is removed away from the roll surface by a wiping action of a pressure gas jetting device 9. For the purpose of more perfectly wiping off the remaining temper rolling mill oil, it is brushed off by a brush 10, and hereby, the surface of the work roll 2 is brought into a very poorly wetted quasi-dry condition. Then the steel sheet P is fed to the dry and quasi-dry work rolls 1, 2 and receives wherein a prescribed temper rolling process, and is finished into the front and back surfaces having said roughnesses. The higher the fineness output of the surface of rolls 1, 2 is, the more favorable they are.

Title: Method for detecting purity of component
Inventor: HAMADA NAOKI
IPC: G01N30/74
Filed: 1991-05-31
Abstract: PURPOSE:To obtain a highly reliable measured result within a short time by calculating the total volume of a three-dimensional chromatograph constituted of a plurality of wavelengths to compare the same with the volume only of the peak caused by a main component. CONSTITUTION:When a sample is injected in a sample injection mechanism 3 in such a state that the mobile phase in a tank 5 is sent to an analytical column 2, each component of a sample forms a zone within the retention time determined by the column 2 and discharged from the column 2 to flow in a spectral analyzing cell 6. Each zone forming component receives the light of an analytical light path 10 to absorb the light having a wavelength determined by the component. The light emitted from a cell 6 is spectrally separated into respective wavelengths and the respective lights are incident to the photodiodes 11 corresponding to the respective wavelengths. The lights of respective wavelengths are converted to electric signals which are, in turn, outputted to a signal processor 1 through a scanner 14. The whole volume of a three-dimensional chromatogrph constituted of a plurality of wavelengths containing impurity is calculated in an apparatus 15. By comparing the obtained volume with the volume only of the peak caused by a main component, the presence of impurity can be judged with high reliability.

IPC: B41J2/175
Filed: 1981-09-30
Abstract: PURPOSE:To meet the need of a liquid contact property and to enable the prevention of the loss of a flow rate, by linking an inlet valve body to the middle part of a lever and to a monolithic intermediate rod, and by connecting the lever to the intermediate rod by a pin. CONSTITUTION:When the device is OFF, a lever 30 is made to be straight by a guide plate 31, and a drain port 14 is opened, while an inlet 12 is closed. When a solenoid coil 70 is turned ON under the condition, a bending lever 30 moves, in a straight state, to the right, and first a drain port 14 is closed by a drain-port valve body 15. In the further movement, the lever is bent at the intermediate part, and thereby the guide plate 31 is separated from the upper half 30b of the lever 30. Meanwhile, a connecting pin 25 only slides to the right along a groove 24. When it touches the right end and rotates, an inlet valve body 20 is separated from a valve seat 21 and opened. By this constitution, a liquid chamber can be constituted by a member meeting the need of a liquid contact property, the loss of a flow rate can be prevented by the simultaneous transitional closure of the inlet and the drain port during the ON-OFF operation of a valve, and thus the load on a pressure pump can be reduced.

Abstract: PURPOSE:To lower the pressure of molding material applied onto a mold surface under the condition that an injection molder is used by a method wherein a closed space at the first position is formed by bringing a first mold and a second mold close to each other and molding material is poured form the injection molder in the closed space and, by bringing the first mold and the second mold further close to each other under the pressure lower than that applied in the previous process so as to compress the molding material in the closed space at the second position in order to fill a cavity with the molding material. CONSTITUTION:When a second mold 2 arrives a point B, sliding contact faces 11 and 21 face to each other so as to surround the periphery of a mold surface in order to form a closed space 6 between a first mold 1 and the second mold 2. Under the state as described above, molten resin is poured from an injection molder into the closed space 6. Next, the oil pressure of a second cylinder device 4 is lowered and, after that the second mold 2 is advanced further by re-starting the driving of the second mold. At this time, the volume in the closed space 6 is gradually decreased so as to compress the molten resin in order to spread the resin in the closed space 6. By the arrival of the second mold 2 to a point C (or at the second position), the closed space 6 forms the predetermined cavity and the second mold 2 and the first mold 1 are clamped together and the molten resin is cast in the cavity.
