Title: Facsimile receiver
Inventor: KUNO TAKASHI
IPC: H04N1/36
Filed: 1979-04-11
Abstract: PURPOSE:To make unnecessary the incorporated oscillator of high accuracy and to ensure the synchronism, by selecting the transmission synchronism system and indepedent synchronous system in the continued time of facsimile transmission signal. CONSTITUTION:The facsimile transmission signal is fed from the input terminal 10 to the separation unit 11, and the video signal is output at the output terminal 18 after it is amplified at the video signal amplifier 14. On the other hand, if the video signal having longer continuous time than the width of the synchronizing signal is absent, the selection instruction unit 12 does not produce the instruction signal, the synchronous signal output 11B is amplified at the synchronous amplifier 13 and it appears at the output terminal 17 via the switch 15, being transmission synchronous system. When the video signal having longer continuous time than the synchronous signal is input, the output 11c operates the selection instruction unit 12 to output selection signal, the switch 15 is selected to the incorporated oscillator 16 for this period, and the oscillation pulse is appeared at the output terminal 17 as the synchronizing signal to establish the independent synchronous system.

Title: Surface acoustic wave resonator
Inventor: YAMAMOTO TAIJI
IPC: H03H9/145
Filed: 1985-03-08
Abstract: PURPOSE:To suppress the undesired vertical mode resonance and to attain the easy conversion into a high frequency as well as easy production with a surface acoustic wave resonator, by arraying plural sets of electrode fingers of the same number containing the cross finger electrodes in a cycle lambda/2 after setting the wavelength of the surface acoustic wave at lambda. CONSTITUTION:The cross finger electrode 32 and 33 are formed by arraying plural sets of electrodes 36 containing three electrode fingers 37 in a cycle lambda/2 with the inter-center distance set at 9/4lambda. The marks (+), (+), (-) and (-) are given to those electrodes 36. Thus the undesired vertical mode resonance is reduced considerably. This is due to a face that the three-in-a-set electrodes 36 are arranged with 9/4lambda spaces and at the same time have marks (+), (+), (-) and (-) respectively. Thus the reflected waves are offset among those electrode fingers and therefore the excellent resonance characteristics can be obtained.

Title: Tentering apparatus of running sheet
Inventor: KATAOKA HIROSHI
IPC: B29C53/18
Filed: 1981-03-30
Abstract: PURPOSE:To prevent the generation of air table phenomenon, by putting only both edge parts of a running sheet between upper and lower rolls and tentering the sheet directly. CONSTITUTION:Two sets of upper and lower rolls are arranged symmetrically right and left so as to put only both edge parts of a running sheet S between. Right and left lower rolls are rotated synchronously each other, being connected by the intermediate part of an expander roll 3. Directions of right and left rolls are directed obliquely outside by an angle theta generating a proper tension T of width direction to the sheet between rolls. By supporting the upper roll 5 by a floating arm 7 in free up and down motion a force advancing the edge part of the sheet S obliquely outside is decided by the frictional force obtained by multiplying the weight of the upper roll 5 with the frictional coefficient between the sheet and the roll, and the tension T of width direction of the sheet S is decided by its partial force of width direction. Thus, generation of air table phenomenon is prevented.
