Title: Mechanism preventing gear disengagement by error in transmission for vehicle
Inventor: NAKAJIMA SHIYUNJI
IPC: F16D23/06
Filed: 1982-06-04
Abstract: PURPOSE:To reduce the drawing power for disengagement, by chamfering a coupling sleeve at each of its abutting portions against a synchro-hub, which abutting portions are provided for preventing the coupling sleeve from getting disengaged from the synchro-hub by error. CONSTITUTION:When released from a shifted state to a neutral state, the coupling sleeve 5 is transferred toward the synchro-hub 2 by disengagement action of a shift lever. As a result, the chambered portion 15 of the coupling sleeve 5 abuts against the chamfered edge 12 of the spline gear 10 on the synchro-hub 2 developing a sliding motion between the chamfered portion 15 of the coupling sleeve 5 and the chamfered edge 12 of the spline gear 10, whereupon the coupling sleeve 5 rides on the shoulder 9a of the spline gear 10 and gets drawn to reach the neutral position. Because of the sliding motion, the resistance in the abutting of the chamfered portion 15 against the chamfered edge 12 can be made smaller than in the case where the edge of the couplig sleeve is not chamfered.

Title: Device and method for controlling and detecting alignment of composite video color frame
Inventor: OVERTON MICHAEL S
IPC: H04N9/79
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To control and detect alignment of a composite analog video color frame. SOLUTION: A decoder 22 decodes a composite video signal from a system 16 to be tested to produce a component video signal and to generate a color frame signal at start of each color frame of the composite analog video signal. Responding to the color frame signal, a flag insert circuit 26 inserts a flag signal to one of plural components of the component video signal to indicate a phase of each frame in the color frame. An analyzer 28 captures the component video signal in response to the flag signal and makes a reference component video signal and the color frame in-phase.

Abstract: PURPOSE:To provide an electrode to the surface of one side of a piezoelectric ceramic plate and to divide the electrode into two pieces and to stick the surface of the other side of the piezoelectric ceramic plate to a metallic diaphragm with a conductive adhesive and to take out a detection signal from between the other electrode and the metallic diaphragm. CONSTITUTION:The electrodes 2a and 2b divided into two pieces are formed concentrically to the surface of one side of the piezoelectric ceramic plate 1. The surface of the other side of the ceramic plate 1 is stuck to the metallic diaphragm 4 with the conductive adhesive 3. When the prescribed driving voltage is impressed on between a terminal P1 connected with the electrode 2a and a terminal Pc connected with the diaphragm 5, the ceramic plate 1 expands and contracts, and oscillates greatly in its diametrical direction mainly. The diaphragm 4 is bent and oscillates almost in an orthogonal direction to the expanding and contracting direction of the ceramic plate 1. When there is an object to be detected at that time, the diaphragm 4 is restrained from bending and oscillating and when there is no object to be detected, the diaphragm 4 is not restrained from bending and oscillating and oscillates. The detection signal according to the quantity of oscillation is taken out from between the terminals P2 and Pc.

IPC: H03M1/80
Filed: 1981-06-24
Abstract: PURPOSE:To obtain analog outputs from which higher harmonic components are removed by driving MOSFETs constituting weighted constant current  sources through time constant circuits. CONSTITUTION:Since the size ratio W/L of channel width to channel length is set to S/L, 2W/L-2<n>W/L in MOSFETs Q0-Qn constituting constant current sources, the current is weighted at I, 2I-2nI. Inverted signals 2<0>-2<n> of digital signals are applied to the gates of the MOSFET Q0-Qn through inverters IV0-IVn and time constant circuits consisting of resistances R0-Rn and capacitors C0-Cn. Consequently the current outputs of the MOSFET Q0-Qn are gradually raised, so that higher harmonic components included in the current I0 outputted from an output terminal P1 is extremely reduced.

Title: Data display method
Inventor: TOYOSHIMA NAOKO
IPC: G06F9/44
Filed: 1991-04-26
Abstract: PURPOSE:To permit a user to confirm the meaning of data by interpreting the meaning of input data, selecting an expression method at the time of data output and generating and outputting output expression through the use of the expression method selected according to the interpreted meaning. CONSTITUTION:An expression method storage part 4 stores plural expression methods at the time of data output. A meaning interpretation part 2 interprets the meaning of data inputted from an input/output part 1. An expression method selection part 3 selects the expression method at the time of a data output from the expression method storage part 4. At this time, the characteristic of the user is detected from a user characteristic storage part 81 and the expression corresponding to the characteristic of the user is preferentially selected. An output expression generating part 5 generates the output expression of input data by using of the expression method selected according to the interpreted meaning and the input/output part 1 outputs it. Thus, even when the user cannot confirm the meaning of input data by specified expression, the user can confirm the meaning in an early stage by expression which is different from specified expression and which is, furthermore, suited to the user.

Title: Magnetic disk device
Inventor: ETSUNO TOSHIHARU
IPC: G11B5/596
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To achieve a high recording density and to enable a high speed operation by using one magnetic head only for recording and the other head only for reproducing. SOLUTION: Magnetic heads 17 and 18 are driven independently from each other by actuators 3 approximately in the direction of a magnetic disk 1, and the use of the magnetic head 17 is limited to digital signal recording, while that of the magnetic head 18 is limited to digital signal reproducing. Thus, this arrangement allows gap lengths or gap widths of the magnetic heads 17 and 18 to be independently designed for optimal constitutions respectively. Therefore, a high recording density can be achieved by increasing the gap length of the magnetic head 17 and setting the track width narrower. Further, since reproducing can be operated independently from recording, this reduces a waiting time and enables a high speed operation.

Abstract: PURPOSE:To simplify the constitution, to eliminate the need for the axis alignment of laser light and to enable ultrasonic flaw detection even in environment where measurement conditions are inferior like a line of a factory, etc. CONSTITUTION:Pulse laser light 1 is made incident on one end of a multi-mode step type optical fiber 8 and then laser light which is projected by the selective mode stimulation of the fiber is in a ring shape. Then probe laser light 3 is made incident on the same fiber to generate a probe light beam which is converged on the ring center part by placing a proper collimator 9 at the output end of the fiber. A body 17 is irradiated with the laser light beam to generate surface ultrasonic waves. Those surface waves can vibrate the periphery of the center and the probe light which is reflected from the center is Doppler- shifted in frequency. This shifted light is returned to the same fiber by the collimator 9 and made incident on a Fabri-Perot interferometer 2, and the shifted frequency and intensity are measured to know information on the surface in the ring.
