Title: Mouse device
IPC: G06F3/039
Filed: 1992-03-11
Abstract: PURPOSE:To attain the stable control of a mouse which is not placed on the flat surface by constructing a mouse to be attracted to a mouse pad. CONSTITUTION:A control circuit 2 judges whether the mouse is in operation or not by means of a touch sensor terminal 1 on a mouse button. Based on the result, current is applied to a coil 4 wound on an iron core 3. When the current flows in the coil 4, the iron core is magnetized so that the mouse is attracted to the mouse pad consisting of iron 7. Thus, the mouse can be operated even though it is not placed on the flat surface.

Title: Grafting robot
Inventor: MIZOTA MORIKAZU
IPC: A01G1/06
Filed: 1995-03-13
Abstract: PURPOSE: To provide a grafting robot having excellent handleability. CONSTITUTION: A stock transporting device 18 is equipped with at least a pair of hycopotyl gripping hands 37 and a pair of hycopotyl gripping auxiliary hands 39 and the shape of the passing face of a cutter blade 116 of a cutter 19 of the hycopotyl auxiliary hands 39 is made into approximately the same as the passage locus of the cutter blade to provide the objective grafting robot. The position determination of a seedling in cutting is prevented from readily becoming unstable and the hycopotyl is fixed. Since the cutting area is lessened and grafting performances between a scion and a stock are deteriorated when the cutting angle of the hycopotyl is an obtuse angle, the most excellent taking activity is obtained when the hycopotyl is cut at 25-30 deg. inclination angle from the vertical line.

Abstract: PURPOSE:To always and constantly write into a disk and to read out from the disk irrespective of the change of a disk condition caused by contamination, wearing, damages, etc., by specifying the internal pressure of a container for housing the driving mechanism, etc., of the disk and a head.

Filed: 1985-03-16
Abstract: PURPOSE:To make an overall frequency characteristic flat by providing a low- rigidity part in the peripheral part of a dust cap to change the rigidity of the peripheral part of the dust cap in the peripheral direction. CONSTITUTION:Four recessed parts 1c each of which has a sharp rise angle and covers 45 deg. are formed in the peripheral part of a dust cap 1 to enhance the rigidity, and projecting parts 1d whose rigidity is relatively low other than recessed parts 1c are a low-rigidity part A. The rigidity of the recessed part 1c is changed in accordance with the rise angle, the depth, and the central angle, and since the rigidity of the peripheral part of the dust cap 1 is changed with respect to place by these recessed parts 1c and projecting part 1d, resonance of a single frequency does not occur but is dispersed into plural subresonances and is distributed in a wide frequency range. Since the rigidity of the rise part of the dust cap is enhanced, the high band frequency range is extended.

Title: Bidirectional impedance converting circuit

IPC: H03H11/40
Filed: 1983-03-31
Abstract: PURPOSE:To obtain an input impedance being proportional to a load impedance, and also to convert easily a titled circuit to an integrated circuit by constituting it of an emitter follower circuit, a voltage comparing circuit, and the first-the fourth current mirror circuits. CONSTITUTION:When voltage V1 rises from a stable state, a current I1 is made to flow by a TR 5 of an emitter follower circuit 6, and in case when an amplification factor betap of the TR 5 is large enough, Ia=I1 is obtained. When a current transfer ratio in a current mirror circuit 23 is denoted as gamma2, and also a base current of TRs 21, 22 is small enough, a current of gamma2.Ia flows in, and in a circuit 33, a current of gamma2 .gamma3.Ia flow out of the output end. In this case, since a TR 4 does not conduct, -I2=gamma2.gamma3.Ia, and accordingly, -I2=gamma2.gamma3.I1 is ob tained. Also, a load impedance is shown by ZL=V2/(-I2). When the voltage V1 rises, the circuits 23, 33 are operated, and in the end, V1=V2 is obtained, therefore, an input impedance Zin becomes like Zin=V1/I1=gamma2gamma3ZL. In case the voltage V1 drops, Zin=gamma1gamma4ZL is obtained in the same way.
