IPC: G11B19/02
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a disk permitting to adjust a relation between registered timer reservation information and timer reservation information recorded on a disk side by reading the timer reservation signal from a timer reservation information storage means, and executing the timer reservation based on the timer reservation information signal and a control signal reproduced by a timer reservation information reproducing means. SOLUTION: Based on the output reproduced by an optical head 4 from a user's data recording region of an optical disk 1, a system controller 14 judges whether or not timer reservation is registered on the optical disk 1. Namely, it judges whether or not a timer reservation information signal and a control signal, which indicates whether execution of the timer reservation by the timer reservation information signal stored in a timer reservation information storage means is accepted or inhibited, are recorded in the user's data recording region of the optical disk 1, and if yes, namely, when it is an exclusive reservation, the reservation is executed only according to the reservation recorded on the disk.

Title: Color paste and its production
Inventor: NOMURA HIDESHI
IPC: C08K5/17
Filed: 1994-06-27
Abstract: PURPOSE:To form a color filter from a polyimide poor in solvent resistance by incorporating a water soluble org. amine more than a specified times mol. equivalent of a carboxyl group of polyamic acid, a pigment and water. CONSTITUTION:The water soluble org. amine binds in base form to the carboxyl group of the polyamic acid and becomes to a water soluble polyimide precursor. Further, when an amount of the water soluble org. amine binding in base form is too low, the polyimide precursor composition does not dissolve to water. In order to easily dissolve the precursor in the water. it is necessary to add >=0.5mol. equivalent water soluble org. amine per polyamic acid. Moreover, in this water based color paste, a pigment is dispersed in an aq. soln. of the polyimide precursor. Methyl amine, ethyl amine, n-propyl amine, 2 ethanol amine, 2-amino-2 methyl 1 propanol are a concrete example of the water soluble orb. amine.

Filed: 1990-06-01
Abstract: PURPOSE:To obtain the composite having bioaffinity, strength and durability in combination by specifying the conditions for a pressurized heating treatment at the time of isotropically pressurizing a container into which the molding of gold- and silver-based metals and apatite are sealed in a contact state and which is evacuated. CONSTITUTION:The molding of the alloy to be joined or the gold alloy or the silver or silver alloy (described as metal M) is brought into contact with the apatite and is sealed in this state into the hermetic container having plasticity to pressures. The container is then internally evacuated. The isotropic pressure and temp. are applied with fluid as a pressure medium to this container from the outside. The pressure is maintained at 50 to 800MPa and the temp. of the container at 100 to 850 deg.C. The pressure below the lower limit is insufficient to make the denser apatite and the pressure above the upper limit is not required. The diffusion joining between the apatite and the metal M is not sufficiently established if the temp. is below the lower limit, and the temp. above the upper limit is not required for the formation of the denser apatite and establishing of the joining. The composite having good quality is obtd. by the tempering characteristic of the metal M according to this method.

These components are fraction collected from a fraction collection port via a fraction collection pipe 7. The bubbles float on the buffer soln. surface if the bubbles exist in the buffer soln. at this time. The bubbles are sucked through a pass filter 19 for gas, a filter retainer 21 and a suction pipe 23 into a vacuum pump 22 and are dis charged to the outside. Namely, the bubbles can be surely discharged even if the bubbles exist in the buffer soln. and, therefore, the sepn. performance of the migration sample is enhanced. In addition, the efficiency of the sepn. operation is enhanced as well as the bubbles can be removed even if a power source is not interrupted.

Abstract: PURPOSE:To offer the device having a stable picture output element by transducing the standard pattern having >=2 levels into an electric signal by a color image pickup element at each start of scanning, recording the data at each picture element unit of the image pickup element and applying standardization at each picture element signal so as to correct variation among sensors. CONSTITUTION:The output electric signal of a CCD line sensor 3 is amplified by an amplifier 4 and converted into a digital signal by an A/D converter 4. This signal is split into three colors, e.g., white, yellow and cyan corresponding to each color filter and stored respectively in line memories 6, 7 and 8. Devices up to 3-5 are operated similarly to CCD elements 3, 3', 3'' and 3''', the signal is stored respectively in line memories 6, 7, 8 and outputted as a one-line signal. The one-line signal at each color is averaged at each two picture elements by a register 9 and an adder 10 so as to eliminate reflected noise due to sampling. Then the standardization to correct shading is conducted to the signal at each picture element at each sensor.
