Title: Fluoroplastics product provided with discrimination display
Inventor: SHIMIZU KENJI
IPC: B41M3/00
Filed: 1989-03-27
Abstract: PURPOSE:To easily apply a discrimination display not erased easily by re-baking a fluoroplastics substrate to temp. equal to or higher than the m.p. thereof and subsequently cooling the same to form granular projections and applying a discrimination display consisting of recessed parts having surface discrimination display shape and the coloring material embedded in said recessed parts. CONSTITUTION:A fluoroplastics substrate 1 is re-baked to temp. equal to or higher than the m.p. thereof and subsequently cooled to form 1000/cm<2> or more of granular projections 2 on the surface of said substrate. Recessed parts 4 having a discrimination display shape are formed to the surface of the fluoroplastics substrate 1. A coloring material 3 is embedded in the recessed parts 4 of the fluoroplastics substrate 1 to obtain a fluoroplastics resin product 10 provided with a discrimination display. A film 8 is closely adhered to the entire front and rear surfaces of the molded product 2 to obtain a fluoroplastics resin product 10b provided with the discrimination display. The film is transparent enough to see the discrimination display due to the coloring material 3 embedded in the recessed parts 4 from the outside and excellent in chemical resistance and the close adhesiveness with the molded product 2 and a film made of fluoroplastics is used. As mentioned above, since 1000/cm<2> or more of the granular projections are formed on the surface of the substrate, the discrimination display or a seal can be bonded in spite of the fluoroplastics product.

Title: Manufacture of cylindrical die board and grooving device
Inventor: YANAGIMOTO CHUJI
IPC: B23K26/00
Filed: 1995-03-06
Abstract: PURPOSE: To retain fixed knives without play by emitting a laser beam in pulse oscillation, while controlling the feeding of a stock for a cylindrical die board in the direction along the axial center and that of the rotation, and machining a knife-embedding grove like a string of beads. CONSTITUTION: An essential cylindrical die board stock 1 is attached to the rotation holding frame 11 of a rotary supporting body 4. While the feeding of the stock 1 is controlled in the direction along its axial center L and in the rotating direction, a laser beam is emitted in pulse oscillation from a laser irradiation nozzle 22 in the direction orthogonally crossing the axial center L. Thus, the stock 1 is machined with a knife-embedding groove 28 formed like a string of beads. The irradiation of the laser being intermittent, a hole with a diameter slightly larger than that of the laser beam is formed in the stock 1. The hole is made in plural numbers continuously to each other at a prescribed pitch to form the knife-embedding groove 28 like a string of beads with a width size large enough to deal with a thick knife.  This knife 28 is provided with plural apexes 29 and capable of preventing play of the knife.

Title: Bias current compensation circuit for operational amplifier
Inventor: HANAWAKA MASUO
IPC: H03F1/30
Filed: 1978-06-20
Abstract: PURPOSE:To automatically compensate the bias current without being affected due to temperature fluctuation, by connecting the resistor to the inverting input or non- inverting input of the operational amplifier to detect the bias current. CONSTITUTION:When the switch SW is OFF, the current ib flows to the resistor Rb, the output of the operational amplifier OP is Rbib(1+R2/R1), and when the switch SW is ON, the output of the amplifier OP is 0. When the switch SW is ON and OFF, the AC output corresponding to ib appears at the output of the amplifier OP and it superimposes on the DC signal voltage Eo=(R2/R1)Ei. The AC output which is sufficiently small to Eo is amplified A, rectified D, and given to the inverting or non-inverting terminal of the amplifier OP via the resistor R3 to reduce the AC output. If the gain of the amplifier A is sufficiently great, substantially Rbib is nearly equal to 0, the current ib is all fed through the resistor R3 to enable automatic compensation. With this constitution, fine current ib can be compensated with good precision by taking the resistor Rb and the gain of the amplifier A greater, through the use of conventional components.

Title: Suppression circuit of search noise
Inventor: KOMATSU KEIICHI
IPC: H04N5/94
Filed: 1984-04-16
Abstract: PURPOSE:To suppress search noises with simple constitution by raising a dropout detection level at the time of the search reproduction than that at the time of the normal reproduction and compensating a search noise occurence period as well as a dropout period. CONSTITUTION:A dropout detection level is not proper when it is too large or small. Accordingly a dropout detection circuit 16 sets an output of a variable gain amplifier 44 as so to be an initial detection level. When gains of the variable gain amplifier 44 at the time of the search are smaller than those at the time of the normal reproduction and an input level of the dropout detection circuit 16 is smaller, a potential impressed on a transistor Q4 becomes smaller. As a result the dropout detection level can be set higher than that at the time of the normal reprodution.

Title: Base station radio
Inventor: OSAWA AKITO
IPC: H04W88/08
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a base station radio by which the communication of a mobile station does not become an interference wave in the area of low output base station radio by varying attenuation quantity with a variable attenuation, changing the noise exponential of a reception part and deciding the radius of an up reception area. SOLUTION: This base station radio (BTS) estimates the outgoing transmission area of the BTS that can arbitrarily adjust the outgoing transmission area range of BTS from the detection voltage value of transmission power by adjusting transmission power. Base station radio varies the noise exponential characteristic of the reception part by appropriately varying the attenuation quantity of a variable attenuator installed in the preceding stage of the reception part. Base station radio controls an incoming reception area range to be similar to the outgoing transmission area range. Even if MS48-1 receives the down transmission signal of BTS44 and makes a call at a point B, it is out of the incoming area range against BTS46. Thus, interference to MS48-4, 48-5 and 48-6 in an area 52 can be avoided.

IPC: G04G13/02
Filed: 1981-05-20
Abstract: PURPOSE:To facilitate demonstration of alarm function while enabling checking of alarm sound for a short time by reducing the time interval thereof through a short time counter responsive to external operation. CONSTITUTION:An AND gate 26 is opened through a switch control circuit 8 with the operation of switches 7 and 7' and one-second signals from a voltage division circuit 2 will be counted with a short-time counter 27 so that AND gates 28-30 are separately opened or closed at intervals of two seconds. As a result, alarm driven waveforms from waveform synthesization circuits 18-20 are applied sequentially at intervals of two seconds to an alarm driving circuit 24 thereby assuring easy demonstration of alarm sound for a short time, in stead of normally switching at intervals of six seconds through a time elapsing circuit 21 or the like. The checking of alarm sounds also can be done for a short time.

Filed: 1992-02-27
Abstract: PURPOSE:To obtain the liquid crystal display device having a high contrast ratio and good liquid crystal quality in an active matrix liquid crystal display of high fineness and high density by coloring or clouding spacer materials. CONSTITUTION:This liquid crystal display device has a pair of transparent substrates 1, picture element electrodes 4 having at least one active elements 5 on the inside surfaces of at least one of these transparent substrates 1, a liquid crystal layer 3 formed between the transparent substrates 1 and spacers 7 formed within this liquid crystal layer 3. These spacers 7 are colored or clouded. Light is shielded in the spacer parts and, therefore, light leakage is decreased when the spacers 7 are colored. The light is not completely shut off but scatters and, therefore, the leakage light decreases when the spacers are clouded. The leakage light of the black display is, therefore, decreased. The material of the spacers 7 is not particularly limited, insofar as the material is org. matter and can be synthesized to a spherical shape; for example, divinyl benzene, etc., are usable.
