IPC: E21D9/12
Filed: 1989-11-15
Abstract: PURPOSE:To miniaturize a system as a whole by conveying a pile of removed earth to the outside of a shield machine as stirring it with a removed earth stirring belt conveyor after adding a mud cross linking agent to the skudgy removed earth excavated out of natural ground with an adding means. CONSTITUTION:Sludgy removed earth 10 excavated out or facing natural ground 2 by a cutter face plate 3 and taken into a cutter chamber 4 is conveyed to the outside of the cutter chamber 4 by a screw conveyor 5 as keeping the inside of the cutter chamber 4 airtight. This sludgy removed earth conveyed to the outside of the cutter chamber 4 is conveyed up to a belt conveyor 16 as being stirred by an earth stirring transfer conveyor 6. At this time, a power or liquid mud grain cross linking agent 13 is added to this sludgy removed earth 10 by a mud grain cross linking agent adding means 14. This cross linking agent 13 is added to the sludgy removed earth 10 in a conveyor pipe 7 from radial four spots of the conveyor pipe 7 constituting the removed earth stirring transfer conveyor 6, so that kneadability between the mud grain cross linking agent 13 and the sludgy removed earth 10 is thus enhanced.

Title: Array probe
Inventor: TANAKA HIROTSUGU
IPC: G01N29/24
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To obtain an array probe in which beam patterns are made uniform and by which the reproducibility and the reliability of a flaw detection capability are enhanced by a method wherein electrodes which are arranged at outermost ends of split electrodes are arranged in such a way that their width size is made larger than every width size of electrodes which are arranged at the inside. SOLUTION: In an array probe, respective split electrodes 11a, 11b are shaped to be parallelograms. As a result, beam patterns 12a, 12b formed at a time when a voltage is applied across the split electrodes and a whole-face electrode 2 supplement intermediate parts between the mutually adjacent electrodes 11a, 11b, and an echo- height drop amount y3 which is generated in the intermediate parts can be reduced. In addition, since every width size w2 of the split electrodes 11a at both ends is larger than every width size w1 of the split electrodes 11b at the inside, the beam patterns 12a which are generated at ends can be made nearly equal to the beam patterns 12b which are generated at the inside.  In addition, when an angle at every acute angle of the parallelogram split electrodes 11a, 11b is set in a range of 45 deg. to 85 deg., even a flaw in a small width of about 1mm can be detected surely by any of the electrodes 11a, 11b.

Title: Thermal transfer medium
Inventor: HAKIRI MINORU
IPC: B41M5/333
Filed: 1987-11-24
Abstract: PURPOSE:To obtain a high-density transfer image superior in resistance to oil and resistance to plasticizer, by using a mixture of a specific compound and a specific phenolic substance as a color developer. CONSTITUTION:In a thermal transfer medium, an accepting sheet is laid over a transfer sheet having a transfer layer mainly composed of a leuco dye so that an accepting layer thereof is in contact with the transfer layer of the transfer sheet. A required color image is formed on the surface of the accepting sheet by being thermally printed from the reverse of the transfer sheet or the reverse of the accepting sheet. A color developer for the accepting sheet makes use of a mixture of a compound shown by a formula I and a phenolic substance shown by a formula II. In this manner, a transfer image superior in resistance to chemicals, e.g., a plasticizer and an oil, can be obtained. In the formula, R1, R2 represent an aromatic heterocyclic ring with 5 or 6 members using a nitrogen atom as a hetero-atom, and the heterocyclic ring forms a complex with a metal ion through the nitrogen atom.

Title: Pll circuit
Inventor: SHINTANI FUMIHIKO
IPC: H03L7/113
Filed: 1992-11-05
Abstract: PURPOSE:To improve the convergence of a phase locked loop(PLL) and to improve high-speed followup ability and the safety of converging operations by fixing the phase comparing result at a specified value just after the PLL is started. CONSTITUTION:An automatic frequency control (AFC) loop is formed by connecting a frequency comparator circuit 11, adder circuit 16, LPF 17 and VCO 18 in the shape of a loop. When the AFC loop as an auxiliary loop is locked and a frequency lock signal is generated at the time of activating the PLL circuit, the phase error signal output of a phase comparator circuit 14 is preset to zero, the contents of a frequency divider circuit 13 and the output phase of a phase reference generation circuit 12 are respectively preset to mutually relating prescribed initial values, and a phase error amount at timing for actually starting phase comparison at the time of PLL start is fixed to the specified value. Thus, since a first phase comparing position just after the PLL start can be set in advance, the convergence of the PLL is accelerated and stabilized. Therefore, it is not necessary to consider any exceptional processing at the time of activation.

IPC: H03K19/086
Filed: 1990-11-01
Abstract: PURPOSE:To obtain an output of either an ECL 100k or an ECL 10k level by devising the output circuit such that either of two different kinds of constant current circuits is switchingly connected to an emitter of a differential amplifier transistor (TR) pair in an ECL (emitter coupled unsaturation logic circuit). CONSTITUTION:With a switching terminal 33 connected to a vCC terminal 15, a TR 32 is turned on and TRs 9,121 are turned off, then a constant current source circuit A is interrupted. Simultaneously, since a power supply VCC is applied to a constant current source circuit B, the constant current source circuit B is connected to a differential amplifier circuit and an output level acts like the mode of ECL 100k. When the switching terminal 33 is disconnected from the vCC terminal 15 or connected to a VEE terminal 18, the constant current source circuit B is interrupted and the TR 32 is simultaneously interrupted, the constant current source circuit A is connected to the differential amplifier circuit and the output level acts like the ECL 10l, mode. Thus, the ECL 1O0k level or the ECL l0k level is selected by the connection of the changeover terminal 33.

Title: Surface protective film and its production
Inventor: HIRAGORI MASAHIKO
IPC: C09J7/02
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To obtain a surface protective film improved in tear strength without increasing the thickness by forming a self-adhesive layer on one side of a substrate produced from a compsn. comprising a specific high-density PE and a styrenic elastomer or a soft PP resin. SOLUTION: A high-density PE in an amount of 100 pts.wt. is compounded with 10-25 pts.wt. styerenic elastomer or soft PP resin. The resultant compsn. is formed into a film by high-neck inflation, i.e., by pulling up the compsn. through a metal mold having a lip clearance of 1-3mm until the frost line height reaches 4-7 times the diameter to the mold and widening to a blow-up ratio of 4-10 to obtain a film thickness of 5-30μm. One side of the formed film as the substrate is coated with a self-adhesive to give a surface protective film. Thus, the tear strength can be increased without increasing the thickness, and the occurrence of film breaking can be prevented.
