Title: Separator of solid foreign matter in liquid
Inventor: TAKEE MASAYOSHI
IPC: B04C5/04
Filed: 1978-08-29
Abstract: PURPOSE: To separate solids from liquid with high efficiency by giving velocity energy and inertia to liquid by letting liquid to be treated fall spirally into an annular space between outer wall and inner wall from the outside.  
     CONSTITUTION: A liquid to be treated sent under pressure to the inlet 15 is changed into a liquid having not pressure energy but velocity energy because the inlet 15 gradually becomes nallower and enters the annular space 13 of the head block 10, whereupon the liquid to be treated is given an inertia by which it is directed to fall down along the inside wall of the body 9 because the inlet path 14 has an opening under the water level. The inertia lowers the consumption of energy by reducing collision resistance encountered in the introduction of liquid to be treated containing foreign matters having downward movement and also causes a strong separating action to take palce on foreign matters concentrating along the inner wall of the body 9 and discharges the foreign matters from the opening 16.

IPC: B65D8/20
Filed: 1989-04-25
Abstract: PURPOSE:To improve the preserving ability by a method wherein low- temperature-melting sealing compound containing chlorinated polypropylene and chlorinated polyethylene is applied between a flange and a brim. CONSTITUTION:Sealing compound 23 is applied nearly all over the area of a brim 12 of a metal lid 11 before wind-seaming takes place. And when the brim 12 of the metal lid 11 and a flange 15 of a container main body 14 are wind-seamed, the sealing compound is compressed to seal the wind-seam part between the brim 12 and flange 15, and low-temperature-melting type sealing compound containing chlorinated polypropylene and chlorinated polyethylene is employed. Thereby, the wind-seam part can be reliably sealed during retort process.

Title: Paper feed table
Inventor: HAYASHI TAKAYOSHI
IPC: B65H11/00
Filed: 1990-04-21
Abstract: PURPOSE:To handle a sheet irrespective of size without problem by actuating a sensor similarly in the case of detecting the sheet of large size by a paper feed table main unit, even in the case of storing an auxiliary paper feed table therein. CONSTITUTION:An auxiliary paper feed table 67 is drawably provided in a paper feed table main unit 66, and the auxiliary paper feed table is prevented from easily interfering in use in a condition that it is not drawn out, by protruding only the paper feed table main unit 66 from a paper fed device. In the case of a sheet guide unstable, a proper feed is facilitated when the auxiliary paper feed table 67 is drawn out. A sensor 84 in a rear part of the auxiliary paper feed table 67, when it is drawn out, detects whether a sheet is of large size or not by detecting the rear end of the received sheet, and the sensor, when the table 67 is stored, is similarly actuated to detection of the sheet by a side of the paper feed table main unit 66 to place the large size sheet in a detection condition, so that judging of a jam, for instance, by an extended paper passing-through time is eliminated.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To realize the simplified and small-sized equalization circuit for an intra-station line termination panel. SOLUTION: A reception signal whose noise is eliminated is normalized by an AGC(automatic gain control) circuit 31. An adder 32 revises a level of an output signal of the AGC 31 in response to a feedback signal. A phase discrimination means 40 frequencydivides a fixed oscillating frequency to use a plurality of signals ϕ1-ϕ8 whose phases are shifted and to sample an output signal of the adder 32 thereby setting a timing corresponding to a rising of the output signal of the adder 32. A sampling means 60 samples the output signal of the adder 32 synchronously with a set timing to generate reproduction data. On the other hand, a BT equalizer 51 and a transfer 52 generate the feedback signal depending on a code of the reproduction data at that point of time synchronously with the set timing and gives the signal to the adder 32.

Title: Extrusion molding device for annular billet
Inventor: MAEDA TOSHIO
IPC: B21K21/06
Filed: 1985-05-21
Abstract: PURPOSE:To prevent the wear of a punch for extrusion molding by dividing said punch to an outer punch and inner punch, inserting slidably the inner punch into the outer punch and bouncing upward the inner punch by means of a spring so that the inner punch is acted with the downward force and slides against the spring force in the stage of molding. CONSTITUTION:The inner punch 3b is inserted into the bore of a billet 1 and the outer punch 3a contacts with the annular top surface of the billet 1 when the punch 3 is moved downward. The billet 1 is pressed by the outer punch 3a and the molding is started when the punch 3 moves further downward. The inner punch 3b descends first at the speed V of the outer punch 3a but the downward force acts on the inner punch 3b when a speed difference (mu-V) from the speed mu of the outflowing billet 1 is generated. The inner punch is thereby slid with the outer punch 3a by overcoming the force of the spring 4. The molding load is thus decreased and the wear of the inner punch 3b is lessened.

Title: Voltage follower circuit
Inventor: NISHIMURA KOICHI
IPC: H03F3/34
Filed: 1988-04-27
Abstract: PURPOSE:To prevent an off-setting voltage from generating by matching the voltage between the base and the emitter of an input transistor and the voltage between the base and the emitter of an output transistor even when an output current is detected and a load current is changed. CONSTITUTION:When it is presumed that the collector current of a transistor Q6 to detect a load current is made into a current I0 and the ground current amplification factor of respective transistors is sufficiently larger, the collector current of transistors Q1-Q6 becomes wholly equal. Namely, by making equal the collector current of transistors Q1-Q4 wholly even under any output load current condition, a VBE(voltage between the base and the emitter) of a transistor Q1 and a VBE of a transistor Q4, a VBE of a transistor Q2 and a VBE of a transistor Q3 are mutually made equal. Consequently, the VBE of respective transistors is mutually canceled, the base potential (input terminal) of the transistor Q1 and the base potential (output terminal) of the transistor Q4 become the same voltage and function as a voltage follower.

Abstract: PURPOSE: To correctly access without lowering recording density by dividing an information recording surface to plural areas in a concentric circular shape and respectively recording a reference signal on plural areas at a prescribed angular interval. CONSTITUTION: When either one between optical blocks 3 or 4 enters an adjacent area erroneously, the timing when sector marks SM are reproduced unmatch in the optical blocks 3 and 4, a phase difference by a time(t) of an angle α where a sector is arranged and shifted is generated. Thus, an optical disk device 1 easily detects whether or not the optical blocks 3 and 4 access correctly an area AR1 of an inner peripheral side and the area AR2 of an outer peripheral side based on the result by obtaining a phase comparison result between sector mark detection signals SM1, SM2 in a phase comparison circuit 32.
