IPC: H03M13/23
Filed: 1993-03-26
Abstract: PURPOSE:To suppress the generation rate of errors low without generating a decoding mistake by dividing a transmission signal into plural blocks and performing a likeli-hood comparing discrimination en bloc to every unit of divided blocks. CONSTITUTION:A record read-out controlling means 11 switches the record read-out for the unit of a data block in a recording means 12 and records likelihood discrimination results 50 into the recording means 12 successively and simultaneously outputs likelihood discrimination results 51 stored at every unit of data blocks en bloc in the recording means 12 to a decoding pass deciding means 13. The decoding pass deciding means 13 decides a decoding pass by the likelihood discrimination results 51 and outputs decoded data 48. Thus, the generation rate of errors is suppressed low without generating a decoding mistake even when undecid-able states of the decoding pass are consecutive.

Abstract: PURPOSE:To improve the discharging characteristics of ink and reduce consumption power by a method wherein the amount of strain of the side walls partitioning a pressure chamber is made larger and, at the same time, the side wall is quickly moved. CONSTITUTION:Piezoelectric member 21, which is polarized to the thickness of a plate, and flat plate-like lowly rigid member 22, the rigidity of which is lower than that of the piezoelectric member 21, are bonded together, Pressure chambers 34 having the depths exceeding the bond area between the lowly rigid member 22 and the piezoelectric member 21 are formed from the surface of the lowly rigid member 22. Under the condition that wiring pattern for energizing the electrodes in the pressure chambers 34 is provided on the surface of the lowly rigid member 22, a ceiling plate 30 is bonded to the lowly rigid member 22. Thus, by reducing the resisting force by the side wall 24 of the lowly rigid member 21 to the strain of the side wall 24 of the piezoelectric member 21, the amount of strain of the side wall 24 is made larger. Further, by allowing to reduce the capacitance between the wiring patterns on the lowly rigid member 22 having low dielectric constant, the current flowing in the electrodes 28 is reduced, resulting in reducing consumption power and, at the same time, shortening the time of the voltage applied to the electrodes 28 for reaching the predetermined voltage so as to quickly move the side walls 24.

Title: Speaker system
Inventor: TAKAHASHI KENICHI
IPC: H04R5/02
Filed: 1978-06-08
Abstract: PURPOSE:To make (n) order air distortion factors zero and reduce the distortion factors of the speaker system by applying two signals of the phases varying by 180 deg./n (n is integer of over 2) to separate speakers and bombining the reproduced sounds of the respective speakers spacially. CONSTITUTION:When two speakers 1, 2 of the same diameter are arrayed and signals x, jx of phases respectively varying by 90 deg. are applied thereto by a phase shift circuit 3, air distortions becomes zero if the air distortions of both at the sound receiving point 4 are combined. Namely, the secondary air distortions owing to the non-linearity of air are perfectly negated. On the other hand, the sums of the basic waves do not become zero, Hence, the sounds free from air distortions may be listened to at the sound receiving point. Since the speaker system is so arranged as to make (n) order air distortion factors zero by applying the two signals of differing phases by 180 deg./n to separate speakers and combining the reproduced sounds of the speakers spacially in this way, the distortion factor may be rduced beyond the theoretical limit of the distortion factors of conventional speaker systems.

Title: Fuel injection valve
Inventor: NIWA YUTAKA
IPC: F02M61/12
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent abrasion of a sliding part of a valve member to be slid on a valve body. SOLUTION: A sliding surface is formed on a sliding part 24 of a needle valve 20 so that the section in the sliding direction may be formed into a projecting shape. The sliding surface is a curved surface having the curved sectional shape in the sliding direction, and the contact area of the sliding surface to the inner peripheral wall of a valve body 13 is relatively small. Moreover, the difference between irregularities in the radial direction of the sliding surface is about 1/100 of the distance between both ends of the sliding surface in the sliding direction. Accordingly, a suitable clearance is formed between the sliding surface and the inner peripheral wall of the valve body 13.  Even if the needle valve 2O is made eccentric when it is reciprocated while being slid on the valve body 13, the suitable clearance is secured between the sliding surface and the inner peripheral wall of the valve body 13. Accordingly, a film of fuel is formed between the sliding surface and the valve body 13, the slide resistance of the sliding parts 24, 28 and the valve body 13 is decreased, and therefore, abrasion of the sliding parts 24, 28 can be prevented.

Filed: 1981-05-08
Abstract: PURPOSE:To eliminate the occurrence of the pulse-like noise which is caused by the switching, by switching the polarity of the vertical deflecting current by means of a switching element having a time constant in coupling to the switching of the inclination of a video reflecting means within a TV camera. CONSTITUTION:A cathode-ray tube 4 displays an image obtained from the image pickup output of a TV camera, and this image is viewed directly through a viwefinder 6a or through a finder 6b after the reflection by a mirror 9. A switching element coupled to the rotation of the mirror 9 is set to invert the polarity of the vertical deflecting current of the tube 4. Thus the inversion of an image caused by the mirror 9 is compensated. For the switching of the switching element, the switching element is turned off after an active state of a certain period of time to avoid the immediate switching to an OFF state. In such way, the pulse-like noise which is caused by the energy stored at a vertical deflecting coil can be prevented.
