Title: Production of photographic substrate
Inventor: TAMAGAWA SHIGEHISA
IPC: G03C1/775
Filed: 1989-02-23
Abstract: PURPOSE:To obviate the generation of stains in a production process without degrading flatness by subjecting the surface of raw paper to a heating treatment at a specific temp. for a specific period of time prior to a corona discharge treatment. CONSTITUTION:The raw paper to be used for the photographic substrate is essentially required to be added with an alkyl ketene dimer as a sizing agent among additives. This photographic substrate is formed by subjecting the raw paper to the corona discharge treatment, then extrusion coating a polyolefin resin on both surfaces thereof. The surface of the raw paper is subjected to the heating treatment for 0.5 to 20 seconds at the temp. higher by >=10 deg.C than the m. p. of the alkyl ketene dimer prior to the corona discharge treatment of this time. When the corona discharge treatment is executed, sticking of the alkyl ketene dimer to a corona treatment roll and a pass roll with which the raw paper web after the corona discharge treatment comes into contact first and the consequent contamination of the rolls are obviated in this way.

Title: Integrated circuit
Inventor: KUDOU MITSURU
IPC: H03H11/12
Filed: 1984-03-12
Abstract: PURPOSE:To obtain an integrated active BPF circuit having a desired characteristic by providing a limiter circuit to an output section of the active BPF composing a resistor, a capacitor and an amplifier so as to absorb the fluctuation of an output amplitude depending on variation in a time constant circuit. CONSTITUTION:The variation of the output amplitude of the BPF circuit attended with the changeover is suppressed by connecting the limiter circuit 16 to an output terminal of the active BPF with time constant switching circuits 12, 13. An input signal from an input terminal 21 is inputted to a base of Trs Q1, Q2 constituting a differential amplifier in the circuit 16 and only the DC component of input signal is propagated because of the capacitance 19. The difference of the input signal is multiplied by a factor of the gain at the differential amplifier and the signal is outputted from a terminal 15 while the upper and lower limit of the output signal is limited because this circuit has a high gain. Thus, even if the input signal amplitude is fluctuated, a limit is given over the output signal by increasing sufficiently the gain of the differential amplifier.

Title: Measuring device
Inventor: UARUTERU SHIYUMITSUTO
IPC: G01D5/36
Filed: 1984-03-12
Abstract: A measuring system includes reference marks provided in the measuring direction alongside the graduation of the scale. These reference marks are absolutely allocated to the graduation and are used to generate reproduceable control pulses. For the identification of each reference mark there is serially allocated to each reference mark a code mark which is made up of code mark segments. The code mark segments follow one upon the other without gaps in the measuring direction, and each includes a homogeneously continuous surface or zone. These code mark segments are arranged in correspondence to their coded information, offset parallel to one another transversely to the measuring direction and are scanned by a scanning field which is integrated in the scanning field used to scan the reference marks. This gapless arrangement of the code mark segments prevents interference with the scanning of the reference marks.

Abstract: PURPOSE: To make the degree of shock absorption adjustable by installing at least two series of orifices having different diameters, and constituting it to rotate and control a disc so as to make one of the orifice series of the disc coincide with the ports of a body. CONSTITUTION: In time of standing still, an electromagnet 22 remains unutilized, a spring 10 becomes extended, and a sleeve 18 hits on a stop abutting contact part. A disc 9 is in such an angular position as making an orifice 11 being large in diameter so as to be coincided with two ports 3 and 4, imparting a relatively soft suspension to wheels.

An iron core 24 is moved in the axial direction, and the sleeve 18 is driven till its slanting edge 24a is abutted to a surface 23a to which a supporting material 23 corresponds. During the process of this axial movement, a rod 15 will rotatively drive the disc 9 by the axial movement of a hole 17.  After having rotated as far as an angle equal to a sector angle being distant from these two ranging orifices 11 and 12, the orifice 12, whose diameter is small, is opposed to both the ports 3 and 4 in a face-to-face manner.
