IPC: H03H9/25
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent generation of spurious or ripples at an output by absorbing the energy of a surface acoustic wave propagating inside a substrate by forming a groove deeper than the wavelength of a surface acoustic wave in the neighborhood of an edge face on the extension of the propagating path of a surface wave, and packing an absorbing material in the groove. SOLUTION: An aluminum interdigital electrode 13 for input and an aluminum interdigital electrode 15 for output are deposited on the surface of a substrate 11 having piezoelectricity such as lithium niobate, and formed in a process such as etching. Then, grooves 17 are formed between the interdigital electrodes 13 and 15 and the edge faces of the substrate 11. The groove 17 is formed by using a dicer or the like at the surface side of the substrate 11. The depth is set almost 1-2 waves of the surface acoustic wave. Then, silicon resin or the like is poured into the groove 17 and solidified so that an absorbing material 19 is formed. It is necessary to fill the groove 17 with this absorbing material 19 in a state that the absorbing material 19 is completely brought into contact with a wall face at the side of the interdigital electrodes 13 and 15.

Title: Method for press-forming glass product and device therefor
Inventor: MURAKAMI AKIRA
IPC: C03B11/00
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To form a semiprocessed goods product with the shrinks generated on the surface of a pressed glass effectively decreased and reduced in grinding margin in shaping the glass product by a direct pressing method. SOLUTION: This method is composed of a stage for supplying molten glass on the forming faces of a lower die, a stage for controlling the glass temp. so that the temp. of the inside of glass is brought close to that of the peripheral part and a stage for pressing the glass by the forming faces of the upper die and lower die, when viscosity of the temp.-controlled glass is within 103.5-106.5 poise. Since the temp. of the inside of glass is brought close to that of the peripheral part and the glass is pressed with a relatively high viscosity, the heat contraction quantity of the pressed glass is made small, and the difference in heat contraction quantity between the inside and peripheral part of the glass is decreased. Consequently, the generation of shrinks on the glass surface is reduced.

Title: Image forming device
Inventor: OHASHI MASATO
IPC: G03G15/08
Filed: 1989-12-27
Abstract: PURPOSE:To maintain the constant gap between a roller member and a photosensitive body more satisfactorily by providing this device with a rotational driving force trans ferring mechanism whereby rotation is transferred in the direction where the roller member of an image forming unit is pressed against the surface of the photosensitive body. CONSTITUTION:A developing gear 8, which constitutes the rotational driving force transferring mechanism, is fixed to one end of the supporting shaft of a developing roller 4. On the other hand, a driving motor is fixed at the device main body. The rotational driving force of the driving motor is transferred to the developing gear 8 through the rotational driving force transferring mechanism, and consequently the developing roller 4 is rotated and driven. In this case, the constitution of the rotational driving force transferring mechanism and the rotating direction are set so that the developing gear 8 produces force F in the direction in which the developing roller 4 is pressed against the surface of the photosensitive drum 1. The coefficient of slide- friction in the driving part of the slidable supporting body 5, arranged on the driving side, is set so that it is larger than that in the follower part. Thus, the constant gap between the roller member and the photosensitive body can be maintained more satis factorily.

Title: Video camera incorporated with still camera
Inventor: NAGANO YASUYUKI
IPC: G10L21/034
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent unpleasant noise at zoom lens drive from being recorded onto a magnetic tape by attenuating an audio signal in interlocking with the operation of the zoom lens controlling a field angle of an image formed onto a film. SOLUTION: A video camera section 3 reaches a recording state by an operation of a video camera operation section 6a. When the camera section 33 reaches the recording state, the attenuation of an audio control circuit 13a is maximized to record no audio signal onto a magnetic tape. The attenuation of the audio control circuit 13 is decreased in a prescribed time and the audio recording by the video camera section 3 restores to the normal state. In the case of the recording state of the video camera 3, when a zoom lens operation section 6c of an operation section 6 is operated, the attenuation of the audio control circuit 13a is maximized to record no audio signal onto the magnetic tape 2. Thus, unpleasant zoom lens operation noise is not recorded onto the magnetic tape 2.  When a stop button of the operation section 6a is operated, the attenuation of the audio control circuit 13a is increased and the camera section 3 is stopped with the maximum attenuation.

Title: Switching method of spindle operation
Inventor: OBA SHUSUKE
IPC: G05D3/12
Filed: 1993-12-13
Abstract: PURPOSE:To smooth the speed commands before and after switching Without being interrupted by forming, just before switching, the values of the bank pulse of primary delay filter processing and error pulse of position loop processing just after the switching. CONSTITUTION:Since a SW 21 is closed at switching, both the value of a bank pulse formed by multiplying the value Vref of a speed command 100 by a constant 25 (Tf) and the value of an error pulse formed by multiplying it by a constant 26 (1/Kp) become zero, and these processings are canceled. Just after switching, the bank pulse and error pulse formed in the spindle general state just before switching are stored in a bank pulse counter 2 and an error pulse counter 4. Since the speed command formed just after switching has the equivalent value to the speed command just before switching by these bank pulse and error pulse, the speed command just after switching is smoothly continued.
