Title: Facsimile receiver
IPC: H04N1/32
Filed: 1992-02-25
Abstract: PURPOSE:To correctly receive speed matching data of 56KBPS by providing a B channel data detecting part and a data thinning part even in the case that speed matching information is not reported in D channel call control procedures. CONSTITUTION:An ISDN interface part 1 outputs a frame synchronizing signal, a clock of 64KBPS, and B channel data. A B channel data detecting part 2 takes the frame synchronizing signal, the clock of 64KBPS, and B channel data as the input and detects whether the 8th bit of B channel data synchronized with the frame synchronizing signal is '1' continuously a preliminarily determined number or more times or not. When the detecting part 2 detects it, a thinning indication signal is outputted to a data thinning part 3. The thinning part 3 takes the clock of 64KBPS as the input and eliminates one clock out of 8 clocks synchronized with the frame synchronizing signal to generate a clock of 56KBPS. This clock is inputted to a G4 communication control part 4, and speed matching data is correctly transferred to a control part 4.

Title: Inspection equipment for die bonding state
Inventor: KAMIZONO KAZUNOBU
IPC: H01L21/52
Filed: 1990-02-19
Abstract: PURPOSE:To recognize the protruding shape of a bonding member from a die, by providing an image sensing equipment, a vertical lighting equipment, a first and a second oblique lighting equipments, and an optical reflector. CONSTITUTION:A vertical lighting equipment is turned on and light 15 is projected. As to the image picked up by an image sensing equipment 12, the following relations exist; the die region A is bright, the bonding member region B and the bonding surface region C are dark, and the region D outside B and C is bright because of the light 15 reflected by an optical reflector 18. Thereby the periphery of a die 3 can be recognized. Since the size of the die bonding surface is known, the recognition is possible even when a part of the boundary between the regions C and D is dropped. When light 16 is projected from an oblique lighting equipment 13, the side surface 3a of the die 3 on the periphery of the bonding member 4 and the part along the facing side surface of the side surface 3a can be recognized according to the new bright and dark difference of the image of the image sensing equipment. When light 17 is projected from a second oblique lighting equipment 14, the side surface 3b of the die 3 and the part along the facing side surface can be recognized. Thus the protruding shape can be recognized when the die bonding member protrudes from the bonding surface. Thereby the bonding process can be surely and easily managed.

Abstract: PURPOSE:To enable variable magnification without increasing the size of a lens barrel part by observing the imprinting position of the visual field range, etc., of a photographed image to be recorded as it is when the image recording of photography is performed. CONSTITUTION:When photography or video image recording is performed, a prism 17 is used instead of an observing direction conversion prism 2.

Abstract: PURPOSE:To obtain an ion pump with a magnetron shape capable of stably discharging even the rare gas by providing a portion having a large inner diameter and a portion having a small inner diameter and a shorter length in the axial direction to form a cylinder so that an electron beam discharged from a magnetron is separated from the suction surface of molecules by means of the portion having a large inner diameter. CONSTITUTION:A cathode 33 is grounded and a potential phia is being applied to an anode 31 by a discharge power supply 36. The magnetic field is uniform and in parallel  with the symmetrical axis. The radius of the portion of the anode 31 having a small inner diameter is made R1 and the radius of the portion having a large inner diameter is made R2. When a discharge is being performed, an electron beam is formed at a space 26 inside a region shown by a chain line in a space encircled by the anode 31 and  cathode 33. The electron beam is brought into contact with the anode through a very thin sheath at the portion having a small inner diameter, and exists in an inner cylinder  with a radius R3 at the portion having a large inner diameter. Since the portion having a large inner diameter inside the anode is separated from the discharged electron beam, the molecules absorbed there are not applied with an electron shock, even the rare gas can be stably discharged in the same manner as a PIG-type three-poles ion pump.

Abstract: PURPOSE:To improve the linearity of the center in the S-shaped frequency characteristic curve by constituting two resonance circuits by a coil and a capacitor respectively, forming each coil as a spiral coil by a conductor foil provided additionally to each insulation board and providing additionally a ferrite plate to a 2nd coil. CONSTITUTION:A 1st resonance circuit 31 is resonated to a higher resonance frequency in the S-shaped frequency characteristic curve and a 2nd resonance circuit 32 is resonated to a lower resonance frequency respectively. A positive portion in an input signal fed to an input terminal 6 is tuned by a 2nd resonance circuit 32 and detected by a diode 18. Then the high frequency component is rejected by a capacitor 24 and a resistor 24 and the result is outputted from an output terminal 7. On the other hand, the negative portion in said input signal is tuned by the 1st resonance circuit 31. Then the signal is subjected to detection by a diode 17 and high frequency component rejection by a capacitor 21 and a resistor 23, and the result is outputted from the output terminal 7. Thus, the linearity at the middle portion of the S-shaped frequency characteristic curve is improved, which is obtained in the relation between the frequency of the input signal and the detection voltage.

Abstract: PURPOSE:To reduce the contact area between the titled tape guide and tapes so as to minimize the sliding resistance between them, by forming numerous recess sections on the outer periphery of the base body. CONSTITUTION:A highly hard surface layer 3 is formed on the outer periphery of a cylindrical base body 2 and numerous recess sections 6 are provided to the outer surface of the cylindrical base body 2.

Abstract: PURPOSE:To reduce the outside diameter of a fixed shield and to prevent formation of an arc on the outer surface of the fixed shield by coating the outer surface of the fixed shield with a heat-resistant insulator, and providing a hemispherical projecting part at the end of a moving contact. CONSTITUTION:When a moving contact 21 separates from a fixed contact 6 to open a circuit, an arc 23 is formed between both contacts and one end of the arc is shifted to a hemispherical projecting part 22, while the other end is shifted on the contact piece 4 of a contact 6 toward the fixed shield 19 and extinguished. Even if the arc 23 is then fired at the shield 19, the shield 19 has a low-electric-field surface on its back and its withstand voltage is not lowered since its outer surface is coated with an insulator 20 made of a fluororesin such as Teflon. Therefore, the shield 19 can be made to have a minimum outside diameter at which it does not obstruct the motion of the contact piece 4, and a fixed base 3 and a cylinder 8 can also be made smaller in outside diameter.
