Title: Method and apparatus for continuously recycling plastic
Inventor: KAKIZAKI ATSUSHI
IPC: B29C48/57
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for continuously recycling plastics which can recycle plastics in a high yield and is durable, highly safe, and small-sized. SOLUTION: A thermal decomposition tube 5, which is induction heated with an induction coil 6, is connected to the delivery end of an extrusion cylinder 1 having a built-in screw 2. A raw material fed to the extrusion cylinder 1 is kneaded and melted therein and then is continuously introduced into the thermal decomposition tube 5 to be thermally decomposed at a high temp. By limiting the functions of a screw extruder consisting of an extrusion cylinder 1 and a screw 2 to plasticization and melting only, the durability and safeness of the apparatus are improved and the treating capacity is increased.

Title: Reflection type fluorescent lamp
Inventor: MAGAI MITSUTAKE
IPC: H01J61/35
Filed: 1987-05-29
Abstract: PURPOSE:To increase an adhesive strength of an reflection layer with a protection layer and to prevent the separation of the reflection layer, by composing the reflection layer of a reflection type fluorescent lamp of a mixed reflection layer of two kinds of titanium oxides having a specific average grain size. CONSTITUTION:A protection layer 2 is formed by applying an alumina sol suspension liquid to an inner surface of a glass tube and baking it after it has been dried. Next, titanium oxide having an average grain size of 0.02-0.05 mum and titanium oxide having an average grain size of 0.02-0.05 mum are added to a polyethylene oxide water solution to make a titanium oxide suspension liquid, which is applied onto the layer 2, dried and baked to form a reflection layer 3. Further, a fluorescent suspension liquid is applied onto the layer 3 to form a fluorescent member layer 4. The use of the titanium oxides of a fine grains as described above permits contact points among the grains and among the layer 2 and the grains to be increased. By this arrangement, an adhesion of the protection layer with a binder is improved even if the binder is composed of polyethylene oxide.

Title: Radio connecting method for cordless telephone set
Inventor: ISHII YOSHITOMO
IPC: H04Q7/38
Filed: 1992-04-24
Abstract: PURPOSE:To prevent the radio connection of the adjacent channels of a master and a slave units of a cordless telephone set and to shorten the connection time by sending the channel data of the channel during transmission from a transmission side and correcting the channel at a reception side based on the data. CONSTITUTION:The master unit 40 adds transmission channel data to an incoming signal from a telephone circuit to be connected and outputs a radio wave from an antenna 49. The radio wave is received by the antenna 37 of the slave unit 30, tuned, detected and amplified at a reception circuit 35 and inputted to a CPU 32 The frequencies of PLL are changed succesively at the circuit 35, however, in the cases of adjacent frequencies tuning is apt to be occurred, so ID data are detected at the CPU 32 and whether or not the data coincide with the ID data stored in a memory 33 is decided. In the case of coincidence, whether or not channel data coincide is decided next. When the channel data are the same at the transmission and reception sides, the response signal of the radio connection is sent to the master unit 40 at the transmission side to be connected. When the channel data do not coincide, a PLL oscillation frequency is reset while being matched with the channel data sent from the transmission side.

Abstract: PURPOSE: To obtain a circuit which features both the AGC and DAGC functions and is easy to be integrated in the IF amplifier circuit common to AM and FM, by using the voltage between both ends of the collector load resistance of the transistor to supply the AGC voltage as the DAGC voltage.  
     CONSTITUTION: The common emitter of the IF differential amplifier, in which the emitters of 1st and 2nd transistor TrQ 1  and Q 2  are connected to each other in the IF amplifier circuit common to AM and FM, is connected to the collector of TrQ 3  which constitutes the constant current source circuit. Then the emitter of TrQ 5  using the AGC voltage as the base input is connectrd to load resistance r 1  common to the emitter, and the collector of TrQ 5  is connected to the power sources of high frequency amplifier and frequency converter circuits 1 and 2 via resistance R 7 . Thus, the current of TrQ 5  is flown by the AGC voltage, lowering the gain of the amplifier consisting of TrQ 1  and Q 2 . At the same time, the overlap voltage r 1  of TrQ 5  is used as the DAGC voltage of the AM high frequency and the frequency converter circuit. And switch SW 1  is turned off in the case of the IF amplification of FM, and thus the collector current of TrQ 5  is turned off.

Title: Method for press forming optical glass element
Inventor: MONJU HIDETO
IPC: C03B11/00
Filed: 1988-05-30
Abstract: PURPOSE:To enable formation of an optical element with a high accuracy at a low cost, by hot-press forming an optical glass gob having macroscopic waves with a press forming mold. CONSTITUTION:An optical glass gob 3 having macroscopic undulation waves is hot-press formed with top and bottom press forming forces 1 and 2 to form an optical glass element (formed lens) 4. The surface of the optical glass gob is instantaneously heated in a moment the optical glass gob contacts the press forming molds and softened according to the above-mentioned method. However, since the interior of the optical glass gob is not instantaneously heated without softening even the interior of the glass due to bad heat conduction of the optical glass, deformation of the optical glass gob is slowly advanced in a state of disconnected macroscopic waves to press form the desired optical glass element without taking in air between the macroscopic waves.

CONSTITUTION:A movable side specular surface 1 mounted with a stamper 3 and an outer circumferential ring 4 which determines the outside diameter size of the resin molded base material 9a are inserted to a movable side outside cylinder 5 and are mounted to the movable side of a molding machine. On the other hand, an outer circumferential ring 13 of the mirror surface is built to a stationary side mirror surface 2a and is inserted to a stationary side outside cylinder 6 which is mounted to the stationary side of the molding machine. A molten resin is packed into the cavity 7a between the outside cylinder 6 and the outside cylinder 5 and is solidified, by which the resin molded base material 9a is obtd. and the step is formed to the outer circumferential part of the surface on the side opposite to the signal surface formed by the stamper 3. The molding burrs formed between the ring 4 and the ring 13 are, therefore, prevented from being formed thicker than the surface formed of the specular surface 2a as shown in the part B of the figure. The bleeding of the adhesive agent in the sticking stage is stopped by the step part in this way and the thickness of the substrate is prevented from increasing in the outermost circumferential part.

Abstract: PURPOSE:To improve production yield and to reduce production cost by artificially forming an electrically erasable PROM with small capacity, i.e., artificial EEPROM. CONSTITUTION:A memory part 1 is an ultraviolet erasing type PROM part consisting of M bits, equally divided into n pages and shown by P1-Pn. The memory capacity of the P1 (1=1-n) is M/n bits and has page markers 2 each of which includes 2-bit ultraviolet erasing type PROM memory cell. Only when exclusive OR of 2 bits of the page marker is '1', the corresponding page is selected, reading and writing can be permitted, and when the exclusive OR is '0', the system is in a non-selecting state. Namely, the non-selecting state is obtained when the page pointer '00' or '11', and when '01' or '10', the selecting state can be obtained. Since the electrically erasable PRM with small capacity, i.e. an artificial EEPROM, can be obtained, the production yield can be improved and the production cost can be reduced.
