Title: Vibration damper
Inventor: OKINO TOSHIO
IPC: F16F7/10
Filed: 1982-03-23
Abstract: PURPOSE:To simplify the structure and provide reliable operation by making up a damper's lock mechanism of a cam and an inertia member which is forced by the cam, while said damper unit converting the relative axial motions of two members into rotary motion to attenuate vibration. CONSTITUTION:With respect to a slow displacement of any target to be damped, such as pipings or so, which is caused by its heat expansion or contraction, an inner cylinder 3 makes slow left and right motion with respect to an outer cylinder 1 and a rotary rod 9 is then turned slowly, providing corresponding turn of both a cylindrical cam 12 and a divided inertia member 16. When the target to be damped is quickly shifted due to the earthquake or so, the inner cylinder 3 makes rapid motion so that the rotary rod 9 and the cylindrical cam 12 integrated therewith are turned drastically. The divided inertia member 16, however, cannot follow those motions due to its inertial characteristic and relatively delays in turning to the cylindrical cam 12, on account of which the member 16 is pressed upward and downward against the resilient force of a coiled spring 29 onto the internal peripheral face of the outer cylinder 21, thus providing the locked condition.

Title: Thin film magnetic head device
Inventor: MATSUURA TSUKASA
IPC: G11B5/60
Filed: 1989-02-28
Abstract: PURPOSE:To drastically shorten an access time by writing information to a magnetic recording medium integrally formed at the tip part of a suspension, and providing a thin film magnetic field, which reads the information from the magnetic recording medium. CONSTITUTION:A suspension 5 held by an arm is possessed, and an integrally formed thin film magnetic head 3 is provided at the tip part of the suspension 5. Further the information is written and read in a condition in which the head 3 is almost brought into contact with the magnetic recording medium. In such a case, a floating head slider is eliminated, the weight of the tip of the suspension can be reduced, and an interval (h) between a head gap 4 and a magnetic recording medium 1 can be made approximately zero. Thus the access speed can be made faster.

Title: Production of unsingle crystal semiconductor
Inventor: YAMAZAKI SHUNPEI
IPC: H01L21/268
Filed: 1989-02-28
Abstract: PURPOSE:To improve mobility of carriers by irradiating an unsingle crystal semiconductor with a light beam having uniform or gentle energy distribution for heating the semiconductor and by moving a second light beam in a narrow range within an irradiation range. CONSTITUTION:An unsingle crystal semiconductor is irradiated with a first light beam 3 having uniform or gentle energy distribution for such a period of time that the semiconductor is not molten and with such a quantity of energy that the semiconductor is not annealed until it is irradiated with a second light beam. According to this method, the mobility of carriers can be improved since the unsingle crystal semiconductor which has been warmed by the first light beam is irradiated with the second light beam and annealed thereby. Therefore, it is possible to obtain an unsingle crystal semiconductor having higher mobility of carriers at a lower temperature, in a shorter period of time and more easily in comparison with conventional methods.

Title: Electronic wrist watch
Inventor: TAWARA IWAO
IPC: G04F10/00
Filed: 1981-03-31
Abstract: PURPOSE:To make it possible to perform pace sound reporting and time measuring by a stopwatch stably by a simple operation, by reporting the pace sound through a pace selecting counter and measuring the time by a stopwatch counter in response to a starting command. CONSTITUTION:When a setting switch is operated and the starting is commanded, the time is measured by a time measuring counter in a unit of a short time interval in a stopwatch circuit. At the same time a terminal C1 in a pace maker circuit 15 is inverted to a high level, and an AND gate 56 is opened through an FF46. When a selecting switch is operated and a terminal C2 is inverted to a high level, a pace reporting signal 56, which has a frequency corresponding to the preset signal based on a pace selecting counter 48, a pace selecting circuit 42, and the like, is outputted through a gate 56. Since the operation is simple and a variable resistor and the like are not required, the stable sound reporting can be performed even though temperature is changed and the measurement of the elapsed time by the stopwatch can be also performed.

Title: Radar reflector
Inventor: HASEBE NOZOMI
IPC: G01S13/76
Filed: 1990-02-28
Abstract: PURPOSE:To obtain the non-directionalness in the horizontal plane by using a horn antenna, setting axes of (n) pieces of horns of the same characteristic to an equal angle interval of 360/n degrees in the horizontal plane and placing radially the opening surface of each horn toward the outside. CONSTITUTION:As for this reflector, 16 pieces of horns having a half-amplitude level, for instance, whose beam width is 22.5 degrees are placed radially from the same center in the horizontal plane at 22.5 degrees angle interval by setting opening surfaces 101, 102... 115, 116 toward the outside. In this case, since 16 pieces of horns of the same characteristic are placed at an equal angle in the horizontal plane, directionalness of the respective horns is superposed at a point of 3dB down. Accordingly, when the reflector is considered to be a transmitting/receiving antenna and synthesized as a whole, a characteristic being non-directional in the horizontal plane can be obtained.

Filed: 1982-03-25
Abstract: PURPOSE:To increase the output of a linear motor by forming a magnetic flux gap in a magnetic circuit having a magnet, a center pole and a yoke and providing a coil in the gap, thereby increasing the current. CONSTITUTION:A magnetic circuit is composed of a magnet 7, a center pole 8 and a yoke 9, and a magnetic gap 12 is formed in the circuit. A coil 6 is formed in the gap 12, and a pair of brushes 15, 16 are attached to a coil 6 through the gap 12. When the brushes 15, 16 are energized from lead wirings 19, 20 and a current flows through the coil 6, the latter is affected by a force by means of Lorentz's force, which is transmitted from a bobbin 4 to a shaft 13, thereby driving a load. Since the bobbin 4 is electric insulator and the conductive metal forming the coil 6 is isolated from the adjacent conductive metal from each other, the current which is flowed to the coil 6 can be increased.
