Abstract: PURPOSE:To increase track density by installing plural positioning lines at the interval of width of a data track in the radial direction of a disk and installing a data track corresponding to a data head each time a servo head corresponds to respective positioning lines. CONSTITUTION:A servo head 6 is composed of reading exclusive-use heads 6a and 6b and in a servo track 2, servo tracks 2a and 2b or 2c and 2d with mutually different recording frequency of servo information are arranged adjacently. At the interval of width of a data track 3, positioning lines l1 and l2 are formed in the radial direction of a disk 1. On the other hand, between the track 2b and the track 2c, data tracks 3a-3d are mutually arranged adjacently. When a head 6 is located on the line l1, a head 7a is located on the central line of the track 3a and a head 7b is located on the central line of a track 3c. When the heads are located on the line l2, they are installed so that they may be located on the central line of tracks 3b and 3d respectively. Thus, track density can be increased.

Title: Fixed quantity discharge method of fluid
Inventor: MORI KIJIYUU
IPC: G01F11/04
Filed: 1978-12-22
Abstract: PURPOSE: To control the discharge of synthetic resin liquid easily and to prevent the attachment of the said resin liquid drops by moving the piston of an injector type feeder vertically by means of rotation of a pulse motor.  
     CONSTITUTION: The threaded rod 2 is turned by the pulse motor 1, the piston 4a of the injector type feeder is moved down through the slider 3 that is screwed onto the threaded rod to inject synthetic resin liquid 6. The injection quantity can be regulated by the drop distance of the slider that determines the drop distance of the piston, that is, by the rotation of the threaded rod by the pulse motor. Also since the piston is raised when the pulse motor is reversed by the setting number of pulses, the remained resin liquid can be sucked to prevent a fall of resin liquid.

IPC: B65B19/04
Filed: 1992-06-19
Abstract: PURPOSE:To correct the position and posture of a wrapping material and prevent wrapping failure and jamming of the material, by making a part in the vicinity of a fixed-pitch conveyor lower than the surface of the conveyor, providing suction holes in the carrying surface in a carry-in position, and connecting them to a negative pressure source, in a device for carrying a paper wrapping-material, etc. CONSTITUTION:A carrying surface 8a' which is lower than the timing belt of a fixed- pitch conveyor is formed by eliminating part of 8b of a carrying table 8', which is close to the fixed-pitch conveyor, as shown by a two-dot chain line. Further, two suction holes 15 are provided in the carrying table 8', in the position slightly away in the carrying direction from the position where a paper wrapping-material W' is placed to be moved, and are connected to a negative pressure source by a tubes 16. In this structure, the wrapping material W' is sucked by the negative pressure of the suction holes 15 when being placed and moved on the carrying surface 8' from the fixed-pitch conveyor. Consequently a brake is applied to cause the entire rear end of the wrapping maternal W' to come into contact with a pusher. Since the pusher pushes the rear end of the paper, the position and posture of the paper can be corrected.

Title: Vibrational gyro
Inventor: FUJIMOTO KATSUMI
IPC: G01C19/5642
Filed: 1995-06-27
Abstract: PURPOSE: To obtain a vibrational gyro from which signals which are hardly affected by magnetic fields are inexpensively detected and which has a high heat resistance by using an LiNbO3 or LiTaO3 single-crystal substrate which causes a polarization inverting phenomenon due to a pyroelectric effect as the piezoelectric substrate. CONSTITUTION: A vibrator 12 contains a regular quadrangular prism-like piezoelectric substrate 14. The substrate 14 is composed of a single-crystal substrate, such as LiNbO3 single-crystal substrate, LiTaO3 single-crystal substrate, etc., which causes a polarization inverting phenomenon due to a pyroelectric effect. The substrate 14 is polarized so that the polarities can be counterposed to each other near the center of the substrate 14 in the thickness direction. The polarizing method of the substrate 14 utilizes a local polarization inverting phenomenon caused by heat and a layer in which spontaneous polarization is inverted is formed by heat-treating, for example, the LiNbO3 single substrate at a temperature which is a little lower than the Curie temperature.  Two polarization electrodes 16 are formed at an interval in the width direction on one main surface of the substrate 14 and a common electrode 18 is formed on the other main surface of the substrate 14.

Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption for preventing a battery from being charged without limit with an induced voltage, when a vehicle motor is idling. SOLUTION: When a hybrid vehicle runs only by an engine 1 at high speed, and a torque command of 0 for driving a motor 3 is generated from a run control unit 9 for a prescribed time or longer, a motor controller 10 checks the induced voltage at the motor 3 on the basis of revolutions of the motor 3 by a revolution sensor 12 and a graph stored in a memory 14, and the result is compared with the voltage of a battery 7 detected by a voltage sensor 11. When the induced voltage is higher than the battery voltage, a weak field current in response to the revolutions of the motor is generated under the control of the field, and voltage is not induced, and the battery is prevented from being charged without limit with the induced voltage.  When the induced voltage is lower than the battery voltage, the field current is not be made to flow, because the battery 7 is not charged even if the induced voltage is generated.
