Title: Bottom dead point correcting device for press machine
Inventor: YAMAMOTO SHIRO
IPC: B30B15/06
Filed: 1988-12-16
Abstract: PURPOSE:To make safe correction without unlocking a die height adjusting mechanism by setting a knuckle fulcrum shaft position freely displaceable in a vertical direction and correcting the position of the knuckle fulcrum shaft according to the fluctuation in the bottom dead point position of a slide. CONSTITUTION:This press machine has a knuckle mechanism 7 which changes the rotation of a crank shaft to a horizontal reciprocating motion and applies this horizontal reciprocating motion as a vertical driving to a plunger 12. The knuckle fulcrum shaft of this knuckle mechanism is formed as an eccentric shaft and is rotated by as much as a proper desired angle, by which the position of the knuckle fulcrum shaft 11 is finely adjusted in the vertical direction. The bottom dead point position of the plunger and mechanism, hence the slide, is vertically moved in this way. The knuckle fulcrum shaft 11 is made vertically movable by rotation of a servo motor 28. Since the knuckle mechanism is mechanically separated from the die height adjusting mechanism 15, there is no need for unlocking the die height adjusting mechanism and the bottom dead point position is safely corrected.

Title: Method and apparatus for recognizing hydroplane phenomenon of vehicle tire
Inventor: BERUTO BUROIIYAA
IPC: B60R16/02
Filed: 1993-12-17
Abstract: PURPOSE: To detect the possibility of the hydroplane phenomenon in the early stage, by detecting the deformation in the circumferential direction of a projection (tread element) of a tire, and evaluating the waveform of the signal. CONSTITUTION: A permanent magnet 3 as a transmitter, is buried in a tread element 1 of a tire 2, and at least two hole generators 4 as the receivers 4 responding to the change of interval to the magnet 3, are installed inside of the tire 2. When the element 1 is deformed in the circumferential direction (the direction of double arrow 5) of the tire 2, the interval between the magnet 3 and the generator 4 is changed, and the change signal is supplied to an evaluating unit 6 each time. The unit 6 takes out the positive pulse on the deformation of the element 1 from the signal waveform, and confirms the inclination of the signal waveform at the center. Then the threshold for the possibility of the hydroplane phenomenon, inputted from an inputting unit 7 is compared with the confirmed inclination value. When the inclination value is over the threshold, a signal indicating the possibility of the hydroplane phenomenon, is outputted, and a displaying or warning unit 9 is operated.

Title: Cm file device
Inventor: SASAKI TOSHIJI
IPC: H04N5/76
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain the CM file device that compresses contents of a semi- mother file. SOLUTION: A mother file 11 has a capacity of reserving entire CMs and records a transmission scheduled CM for the time being to a semi-mother file 12 having a prescribed recording capacity. A semi-mother data management section 14 manages recording to the semi-mother file 12 and a semi-mother data generating logic section 15 transmits CMs recorded in the semi-mother file 12 respectively. The recording of CMs to the semi-mother file 12 is made based on transmission schedule of one day and since the recording capacity of the file 12 is limited, the file 12 cannot record the entire CMs at once. Thus, after the transmission of a prescribed amount of CM, the transmitted areas are overwritten depending on the end of transmission. It is convenient at reproduction by managing the recording so as to make CMs consecutive for each CM group to be transmitted continuously.

Title: Noise suppressing circuit
Inventor: MIYATA SHINJI
IPC: H04B1/10
Filed: 1987-12-18
Abstract: PURPOSE:To widely decrease externally fitting parts in case an integrated circuit is obtained by utilizing the delay time of a celamic filter CF, which is originally used in an FM radio receiver, without using a delay circuit by an LPF. CONSTITUTION:For the IF signal of an intermediate frequency amplifying step to receive a pulsative noise, distortion is received in the amplitude of the signal. The IF signal before passing through the celamic filter CF is inputted to a first detecting circuit ND1. The first detecting circuit shapes the IF signal to receive the amplitude distortion and the envelop of the signal is detected. The amplitude distortion of the IF signal due to the pulsative noise can be generated in both positive and negative direction. Full-wave shaping is executed by a second detecting circuit for the distortion in these both directions. Since an FM detecting output to receive the pulse noise can be obtained by detecting the IF signal to pass through the filter CF, the output is delayed only by a delay time by this filter CF. When this pulse noise appears in a gate circuit G, since the gate circuit G is closed by a single stable multi-MM, the noise does not appears in an output edge.
