Title: Exhaust gas filter regenerating device
Inventor: KAKEGAWA TOSHIAKI
IPC: F01N3/02
Filed: 1987-02-16
Abstract: PURPOSE:To improve the regeneration efficiency of an exhaust gas filter by estimating an exhaust gas temp. from the output signals of an exhaust gas temp. sensor and the rack position sensor of a fuel injection pump to control an EGR valve, and keeping an exhaust gas temp. to the optimum. CONSTITUTION:When a vehicle is traveling, first, whether the detected value of the pressure of exhaust gas by an exhaust pressure sensor 34 gets above an allowable value or not is judged by a control means 24. And, when judged yes while also detecting that the vehicle is traveling on an expressway with its vehicle speed by a vehicle speed sensor 26 being above a set value, it is judged whether an exhaust gas temp. by a temp. sensor 28 is above a defined value (approx. 400 deg.C) or not. When judged no, a butterfly valve 18 is closed to increase the exhaust gas temp. When judged yes, on the other hand, a timer is driven and an EGR valve 20 is controlled over a set time to obtain a defined value of an EGR ratio, and the exhaust gas temp. is maintained at the temp. (approx. 600 deg.C-700 deg.C) necessary for the regeneration of a particulate filter 12.

Title: Speed detector
Inventor: KUROIWA AKIHIKO
IPC: G01P3/44
Filed: 1987-02-16
Abstract: PURPOSE:To detect the actual speed of a motor at all times by calculating an amount corresponding to the error of the same frequency as that of the output signal of a position detector from speed signal obtained by differentiating the output signal of the position detector and detecting phase difference between said amount corresponding to the error and the output signal of the position detector and the amplitude signal of said amount corresponding to the error. CONSTITUTION:The output signal theta of a position detector 2 for detecting the rotational angle of a motor 1 to be detected is differentiated in a speed calculating circuit 10 to obtain speed signal omegaS. Then, error signal omegaM with the same frequency as that of the signal theta is detected from the signal omegaS in a band-pass filter 11 and phase difference signal PD between the signal theta and the signal omegaM is obtained in a phase difference signal detecting circuit 12. On the basis of the output signal PDL of a low-pass filter 13 and the output signal AL of another low-pass filter 15 passing an amplitude calculating circuit 14, error angle signal thetaM is calculated in a sine wave generating circuit 16. Then, the signal thetaM is subtracted from the signal theta in an actual angle calculating circuit 17 and its output signal thetaT is further differentiated in an actual speed calculating circuit 18 to calculate the actual speed signal omegaT of the motor 1.

Title: Constant load seal device for valve for high vacuum
Inventor: ISHIGAKI TSUNEO
IPC: F16K31/122
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To make the size of a valve for high vacuum as small as possible when it is provided with a constant load seal device by employing a leaf spring instead of a coil spring of a conventional over-travel mechanism. SOLUTION: A plurality of ports communicating with the valve chest 11 of a valve body 10 via pipes are formed and an actuator for actuating a valve rod 19 is arranged adjacent to the valve body 10. A valve seat is formed in a flow passage joining the valve chest 11 to one pipe and the flow passage is closed by putting the seal rubber provided on the valve body at the base end of the valve rod 19 into contact with the valve seat and is opened by separating the seal rubber provided on the valve body from the valve seat. The driving force of the actuator is transmitted from a driving member 25 to the valve rod 19 via a leaf spring 1. The driving member 25 is provided around the valve rod 19 such that it can reciprocate and the movement thereof is regulated. This prevents a load transmitted to the valve rod 19 from the driving member 25 from exceeding a predetermined amount.

Title: Manufacture of surface acoustic wave device
Inventor: YAMADA YOSHIAKI
IPC: H03H3/08
Filed: 1985-02-20
Abstract: PURPOSE:To improve the pattern accuracy and to ensure the required film thickness by using a laminate film supporting the photosensitive substance film as one face of the base film and using the photo masking method to decide the remaining pattern of the absorbing body of the spurious surface acoustic wave. CONSTITUTION:The laminate film 13 supporting a low melting point photo sensitive substance film 12 having a prescribed film thickness on one face of a high melting point and transparent base film 11 is laminated to the entire face of a wafer 10 including transducers 2, 3 by using the film 12 as a press contact face. Since the laminated film 12 is coated and supported on the base film 11 in advance, the sufficient thickness to absorb the spurious surface acous tic wave is ensured. The film 12 is exposed by an ultraviolet ray via a photo mask placed on the film 11. The film 13 whose bonding force is deteriorated by the exposure is exfoliated from the film 11. Thus, the photo sensitive sub stance film of the remaining part acts like a spurious surface acoustic wave absorbing body.

Title: Piezoelectric coupler
Inventor: TSUNEMATSU TOYOAKI
IPC: H03H9/56
Filed: 1987-02-14
Abstract: PURPOSE:To prevent the transmission of noise from an input electrode pair to the output electrode pair by placing a space for separating input and output to both major planes opposed to each other of a piezoelectric substrate so as to apply electrostatic shield to the input and output electrode pairs. CONSTITUTION:A space 39 for separating the input and output is placed to both opposed major faces and the input electrode pairs 33, 34 and the output electrode pairs 35, 36 are formed thereto. Then ground electrode pairs 37, 38 are formed to the space 39. A signal voltage applied to input terminal pairs 41, 42 is extracted as a signal voltage at the output electrode pairs 35, 36. In this case, since the earth electrode pairs 37, 38 are formed between the input electrode pairs 33, 34 and the output electrode pairs 35, 36, no electrostatic coupling exists between the input electrode pairs 33, 34 and the output electrode pairs 35, 36, and the transmission of noise from the input to the output because of the electrostatic coupling between the input and output is prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent interruption of photographing due to a worn-out battery. SOLUTION: In the case of taking a snapshot, a check level of a battery is set depending on an image data quantity stored in a storage element and when a shutter is released before transfer of image data from the storage element to a recording medium is finished, a detected battery voltage is compared with a check level setting value to discriminate propriety of photographing a succeeding frame. In the case of continuous shooting, the check level of the battery is set on the basis of a continuous shooting number setting value, a compression rate of image data and a file size of the image data and the detected battery voltage is compared with the check level setting value to discriminate the propriety of photographing the succeeding frame.  Or the continuous shooting available number is decided on the basis of the continuous shooting number setting value, the compression rate of image data and the file size of the image data to limit the photographing number in the case of the continuous shooting to the continuous shooting available number. Thus, interruption of the photographing due to a worn-out battery can be prevented.
