Title: Composite magnetic head
Inventor: YOSHIDA SATOSHI
IPC: G11B5/29
Filed: 1986-08-29
Abstract: PURPOSE:To record two types of signals on the same disk and to ensure a highly accurate tracking action by using magnetic heads to form the sound signal tracks adjacently to the picture signal tracks via the prescribed guard bands. CONSTITUTION:A sound signal magnetic head 30 and a gap part 33a are provided at the positions in parallel to gap parts 13a and 23a of picture signal magnetic heads 10 and 20 and also distant toward the track width Tw by a distance l respectively. The picture signals are recorded on tracks 61 and 62 of a magnetic recording disk 60 by heads 10 and 20. While the sound signals are recorded by the head 30 onto a track 63 set between both tracks 61 and 62 via a minute guard band corresponding to the distance l. Thus the sound signals are recorded without decreasing the number of tracks for picture signals. Furthermore, the crosstalk can be satisfactorily reduced because both heads are separate from each other by a prescribed distance. Thus, a highly accurate tracking action is ensured without using a large magnetic head.

Title: Data storing system for image memory
Inventor: HORI TATSUHIKO
IPC: H04N5/907
Filed: 1987-08-17
Abstract: PURPOSE:To improve the availability of an image memory by dividing this memory into a planes in the same number as the maximum bits needed for expression of a single image element and using all or partial planes via a continuous address common to those planes and in response to the number of bits to store image data.

For image data #0 and #2 on four planes of a figure (b), the data on the four planes of the relevant numbers are stored in an area including addresses An, An-3, An-4...A0 of the highest bit An equal to 1 respectively. For image data #1 and #3 on a single plane of a figure (a), the data on the single plane is stored in an area including addresses An, An-1...A0 of the most significant bit An equal to 0 respectively. In such a way, those image data #0, #1... are distributed to the addresses of a continuous memory space common to the planes M0-M3 and stored there. As a result, the memory availability is improved.

Title: Phase locked loop oscillator
Inventor: MATSUMURA EIICHI
IPC: H03L7/10
Filed: 1992-07-30
Abstract: PURPOSE:To shorten a lock-up time by quickly raising a low pass filter (LPF) by a comparator during a prescribed period after impressing power supply voltage, and separating the LPF after the lapse of the prescribed time. CONSTITUTION:A frequency divider 12 divides the frequency of an output from a variable voltage control type oscillator 11 and a reference signal generator 13 outputs a signal with reference frequency. A phase detector 14 detects a phase difference between an output signal from the frequency divider 12 and a reference signal from a reference signal generator 13 by mutually comparing both signals and generates an output corresponding to the phase difference. The LPF 15 converts the output of the detector 14 into DC control voltage by smoothing the output as control voltage for the oscillator 11. A comparator 16 compares the control voltage obtained from the LPF 15 with reference voltage VR1. When the voltage of a terminal 21 is lower than the reference voltage VR1, a capacitor in the LPF 15 is quickly charged through the comparator 16. After the lapse of the prescribed time, switches SW1, SW2 are switched.

Filed: 1983-11-01
Abstract: PURPOSE:To obtain a cationizing agent contg. less quantities of unreacted materials and by-products, by neutralizing a tert. amine with a specified org. acid and reacting it with epichlorohydrin. CONSTITUTION:A tert. amine of the formula (wherein R1, R2, R3 are each CH3, C2H5) is neutralized with an equimolar quantity of a monobasic org. acid of the formula R-COOH (wherein R is a 1-8C alkyl, phenyl) having a dissociation constant (PKa) of 4 or above and then reacted with epichlorohydrin. Examples of the org. acids are acetic, propionic and, benzoic acids. It is not preferred from the viewpoint of the subsequent cationizing reaction of polymers that the resulting cationizing agent contains a large quantity of unreacted epichlorohydrin. When trimethylamine is used, it is preferred to use epichlorohydrin in a quantity of 0.95-1.08mol per mole of the amine.

Title: Container for storage and transportation
Inventor: TAKEDA KIKUO
IPC: B65D85/86
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To maintain pollution conditions within the container by forming the surface parts of a container interior part of any one of metal, glass, ceramic, and quartz or a combination of these substances except a fluorine polymer material part, and employing fluorine polymer material among constitutional parts as a press sealing material. SOLUTION: A container main body 1 and an open and close part door 2 for taking in and out a sample is made of aluminum. A metal holding member 4 of a wafer 3 is manufactured of stainless steel. A gasket of a vinylidene fluoride-propylene hexafluoride copolymer is used for a press sealing material 5 for sealing the space between the open and close type door 2 and the main body 1. By this construction, since metal is employed in a surface part to be exposed to air on the inner surface of the container, a pollution substance of an organic component or inorganic ion element never occurs from the main body part 1 or door 2. Furthermore, organic component pollution or inorganic ion component pollution caused by the air can be solved because of attachment of the press sealing material 5 of a fluorine polymer material.
