Title: Method for discharging dust in dust collecting apparatus
Inventor: TSUJIMOTO KIYOSHI
IPC: B04C5/15
Filed: 1980-10-21
Abstract: PURPOSE: To discharge dust continously even if pressure in a dust collecting apparatus is negative by discharging the same while opening moment due to dust accumulation is balanced with closing moment due to a balance weight.  
     CONSTITUTION: An eccentric damper 10 is provided to a lower dust discharge port of a cyclone 1 and opening and closing of said damper 10 are balanced by a balance weight 11. When dust is sufficiently accumulated on a valve plate 10 of the damper, opening moment is increased and becomes larger than closing moment due to the balance wieght 11 and the damper is gradually opened and a part of the dust begins to fall. When a falling amount is increased, the valve plate 10 is closed by action of the balance weight 11. Therefore, only in an amount of the dust accumulated in a condition keeping a definite height h, the dust is discharged and, without varying inner pressure, can continously discharged.

Inventor: ODA KAZUTAKA
IPC: B05D3/02
Filed: 1995-05-23
Abstract: PURPOSE: To greatly improve a drying speed by curbing a long-sized band-shaped body traveling continuously in a drying chamber by supply of gaseous flow to increase the contact area with heating rolls in a device for guiding the long-sized band-shaped body by plural rolls including the heating rolls to dry a coating film. CONSTITUTION: The long-sized aluminum band-shaped body 1 which travels continuously while the body is guided by the cylindrical guide rolls R is coated with a photosensitive resin contg. an org. solvent by a coating section 2, by which a coating film is formed thereon and, thereafter, the band-shaped body is introduced into a first step drying zone 3. The gas supplied from an air feed port 5 is regulated in flow by a flow regulating plate 9 disposed along the traveling direction of the band-shaped body 1 and is brought into contact with the coating film on the band-shaped body 1, by which the org. solvent is evaporated.  Next, the band-shaped body 1 arrives at a second step drying zone 4 where the band-shaped body is brought into contact at a contact angle (a) with the heating roll R1 and is thereby heated up; thereafter, the band-shaped body is guided to the next heating roll R2 while maintaining the prescribed spacing from the arc-shaped rear surface 13 of an air blow-off box 11. The band-shaped body is thus sufficiently dried.

Abstract: PURPOSE:To attain normal reception and transmission even if a frequency of a noise signal is overlapped on a frequency of a carrier signal by applying frequency modulation linearly to a carrier pulse to transmit a transmission code, retarding each frequency component of the carrier pulse at the reception side and compressing and synthesizing the component on a time axis to decode the transmitted code.

Each pulse Pc of the carrier signal Sc is a sinusoidal wave SW whose frequency is changed linearly between pulse width W as shown in a figure. Then a signal received by a photodiode 41 is given to a matched filter 44 via a preamplifier 42 and a limiter 43. Each frequency component in each carrier pulse Pc is delayed by a different delay time and compressed and synthesized on time axis.

Filed: 1983-08-17
Abstract: PURPOSE:To enable to bond a semiconductor chip by a soft brazing material on a heat sink substrate by using a composite alloy metal plate which selects thermal expansion coefficient as an intermediate plate. CONSTITUTION:In a semiconductor device in which a semiconductor chip 6 is bonded through an intermediate metal plate 7 on a heat sink substrate 9, a metal composite plate such as a clad plate in which oxygenless coppers having the same thickness are bonded by a cold rolling method at both sides of an iron- 36% nickel alloy having small thermal expansion coefficient is used as the plate 7. Then, the coefficient is decided to be the prescribed value, i.e., larger than the value produced by adding 1/4 of the difference between the thermal expansion coefficient of the substrate and that of the chip to the thermal expansion coefficient of the chip and smaller than the value produced by adding 3/5 of the difference between the thermal expansion coefficient of the substrate and that of the chip to that of the chip. Thus, since the chip 6, the plate 7 and the substrate 9 can be bonded thereamong with a soft brazing material 8, the reliability can be improved as compared with the conventional one that the substrate 1 and the plate 7 are bonded therebetween with the brazing material.

Filed: 1990-06-07
Abstract: PURPOSE:To reduce dispersion of thickness and thermal deformation by using an etched plate material as a metal layer for constituting a piezoelectric transducer. CONSTITUTION:A piezoelectric transducer 1 is constituted of a piezoelectric ceramic 13, an electrode layer 14 made of a thin film metal layer such as Au, and a metal plate 12 of Ni-Fe alloy. A nozzle formation member 8 has a nozzle opening 9 arranged opposing to the piezoelectric transducer 1. The piezoelectric ceramic 13 is stuck to the etched Fe-Ni alloy 12 by a conductive adhesive 10. The Fe-Ni allay is used as the metal plate 12 so as to obtain a thermal expansion equivalent to the piezoelectric ceramic 13. As the Fe-Ni alloy is used, a piezoelectric transducer which does not make displacement dependent on temperature can be obtained even if the heat curing conductive adhesive 10 is used. The Fe-Ni alloy is heat-treated before an etching in order to stabilize the thermal expansion. For example, when a median of a thickness of the metal plate 12 is made to be 50mu, it is easy to confine thickness dispersion within 1% by a roller.

Title: Magnetic tape checking method

Filed: 1984-07-20
Abstract: PURPOSE:To facilitate an easy optical check of a magnetic tape by reflecting the light by a magnetic head at the other side and through a magnetic recording track and using a magnification optical system to check a reflected image of said track. CONSTITUTION:Gaps Ga and Gb of a magnetic head for magnetic recording have different azimuth angles and have contacts with a magnetic tape 5 at different angles respectively. Thus video signal tracks 6a and 6b are formed. These tracks have different recording directions. Then the parallel beams are irradiated to the tape 5 after development from the direction approximately orthogonal to the direction of the gap Ga. Thus the light is not reflected from the track 6a owing to the gap Ga. Instead the light is reflected from the track 6b owing to the other gap Gb. Then the reflected image of the magnetic track is checked by a magnification optical system. This facilitates an easy optical check of a magnetic tape.
