Title: Magnetic disk reproducing device
Inventor: MOTOTSUGU RYUZO
IPC: H04N5/95
Filed: 1986-09-09
Abstract: PURPOSE:To almost perfectly remove skew distortion generated at time of field reproduction, by reducing a constant amount of charge in a capacitor which charges a horizontal AFC detecting voltage, synchronizing with a phase signal (PG signal) obtained at every revolution of a magnetic disk. CONSTITUTION:At time of the field reproduction, a PG coil 3 generates a PG pulse at every prescribed position of one revolution of the magnetic disk 1, and an AFC detection circuit 16 charges a detected output corresponding to the phase difference of a horizontal synchronizing signal to a capacitor 18 through a resitance 17. By triggering a monostable multivibrator 13 by the PG pulse, a constant amount of accumulated charge in the capacitor 18 is discharged through a resistance 15 and a diode 14, and the constant quantity of the phase of the oscillation of a horizontal oscillation circuit 19 changes considerably faster than the time constant of an integration circuit. In this way, a horizontal AFC following immediately to the disturbance of the horizontal synchronizing signal according to field switching, can be applied, and thereby, the generation of the skew distortion due to the disturbance of horizontal synchronization being generated on the display screen of a CRT11 can be suppressed at minimum.

Title: Automatically storing device for object to be lifted and collected
Inventor: TANAKA KOZO
IPC: B64D1/22
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To store a hanging object in an airframe in such a way that it does not collide with the bottom of the airframe by detecting the vibrating motion of the hanging object in air. SOLUTION: At the time of lifting and collecting a hanging object 28 from an aircraft via a cable, an optimum lift starting timing is calculated on the basis of a circuit which detects the vibrating states i.e., coordinates, speed, period, etc., of the hanging object 28, and of this vibration data, and a drive system is put into lifting action at that timing so that the hanging object 28 can be stored in the airframe 14 without colliding against the bottom of the airframe when lifted. If the vibration is large, whether or not the vibration is within the range that permits storing of the object is determined in order to stop lifting.

Title: Microwave irradiation tank
Inventor: KONNO HIROYUKI
IPC: H05B6/78
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent microwaves from leaking by employing a mechanism for moving a container to be heated in a specified direction on a carrier table. SOLUTION: An empty zone is formed in the upper left corner of a carrier table 3 in the initial state. Upon starting microwave oscillation, a cam plate 451 starts rotation. Following this, as four pushing arms 42L, etc., are individually urged to rotate in sequence through rotary shafts 43, seven micro-plates M are urged to move along each side of a rectangular container guide 41 continuously in sequence. As a result, the micro-plates M are constantly transferred on the carrier table 3 and microwaves oscillated in a housing 1 are uniformly irradiated to each micro-plate M. Since the housing 1 and the carrier table 3 are made of materials that do not transmit microwaves, the microwaves are prevented from leaking outside.

Inventor: MORI KAZUNORI
IPC: B62D113/00
Filed: 1988-08-26
Abstract: PURPOSE:To stabilize the steering responsiveness and the vehicle behavior by carrying out the auxiliary steering control on the basis of the steering angle signal in the steering with a large steering angle exceeding a prescribed value and carrying out the auxiliary steering control on the basis of the vehicle behavior signal in the steering with a small steering angle less than a prescribed value. CONSTITUTION:A vehicle steering device is equipped with a front wheel steering device 1 for steering front wheels according to the driver's operation and an auxiliary steering controller 4 equipped with a controller 3 for carrying out the auxiliary steering control for at least one between the front and rear wheels on the basis of the detection signal supplied from a prescribed detecting means 2. In this case, a steering angle sensor 201 and a vehicle behavior sensor 202 as detecting means 2 are provided. When, in the controller 3, the steering angle exceeds a prescribed value, auxiliary steering control is performed on the basis of the steering angle signal, while if the steering angle is less than a prescribed value, auxiliary steering control is performed on the basis of the vehicle behavior signal. Therefore, the steering responsiveness in the steering with a large steering angle is stabilized, and at the same time, the vehicle behavior in the steering with a small steering angle is stabilized.

Title: Thermal head
Inventor: SUZAKI MASABUMI
IPC: B41J2/335
Filed: 1985-09-27
Abstract: PURPOSE:To obtain a thermal head optimized for high printing quality even when low smoothness paper is used as transfer paper, by constituting said thermal head so that the uppermost part of a heat generating element is higher than the uppermost part of an electrode. CONSTITUTION:The configurational dimension of a partial glaze layer 3 is set so that the height H2 of the uppermost top surface of a heat generating element 4 larger than the height H1 of the uppermost parts of electrodes 7, 8. By this setting, because the thickness of the protective layer 9 formed on the upper layer of the electrodes 7, 8 and the opening part A of the heat generating element 4 by vapor deposition is usually uniform, the height H4 of the uppermost part of the protective layer 9a on the upper layer of the opening part A of the heat generating element 4 is larger than the height H3 of the uppermost part of the protective layer 9b on the electrodes 7, 8. If dimensional relation is set as mentioned above, the protective layer 9a on the upper layer of the opening part A of the heat generating element 4 is brought into contact with the surface of transfer paper first of all through an ink ribbon 5. From the result of experiment, if it is set that H2 is larger than H1 by about 5mum or more and H4 similarly is larger than H3 by about 5mum or more, the good contact of the protective layer with the surface of low smoothness paper is obtained.

Abstract: PURPOSE:To clean a substrate transfer mechanism without exposing the inner wall of container therefor to the atmosphere by providing a mechanism for removing dust particles and contaminants adhering to the transfer mechanism at least partially without exposing the inner wall of the container to the atmosphere. CONSTITUTION:A transfer mechanism 101 can be cleaned in a transfer mechanism cleaning chamber 105. When a gate valve between the cleaning chamber 105 and a transfer chamber 102 is opened, a slit for just passing a transfer arm appears. Differential evacuation then takes place with higher vacuum prevailing on the cleaning chamber 102 side. When the transfer mechanism is cleaned, the differential evacuation is effected by introducing Ar from the transfer chamber 102 side. This constitution blocks intrusion of dust particles or contaminants from the cleaning chamber 105 side to the transfer chamber 102 side.

Title: Synthetic resin container lid with effluent amount controlling function
Inventor: OMI HIDEHIKO
IPC: B65D47/06
Filed: 1988-08-30
Abstract: PURPOSE:To control stably the liquid amount which is discharged through the effluent tube part in a prescribed range by arranging a control device which controls the rotary opening movement of a rotary opening plate to a prescribed acute angle. CONSTITUTION:While holding the drum part of a container by one hand, if the container is made to tilt, a liquid in the container flows toward a mouth part 38 and collides with the lower surface, i.e., the inner surface of a rotary opening plate 8 and makes the rotary opening plate 8 open. At the time of opening of the rotary opening plate 8 in this manner, a connecting piece 32 gives an elasticity deformation. When the rotary opening plate 8 is opened to a prescribed angle position, a protrusion 36 which is formed on the upper surface of the rotary opening plate 8 comes into contact with the inner peripheral surface of an effluent tube part 16, and the rotary opening plate 8 is prevented from further opening. Therefore, even when a consumer makes the container tilt hastily, the opening motion of the rotary opening plate 8 is assuredly controlled. So the excessive liquid which is discharged from the mouth part 38 through the effluent tube part 16 of a container lid 2 is assuredly prevented from suddenly discharging.
