Title: Manufacture of boron steel excellent in cold workability by controlled rolling
Inventor: NISHIDA KAZUHIKO
IPC: C21D8/00
Filed: 1978-11-07
Abstract: PURPOSE: To improve the cold workability of a low alloy steel contg. Cr as it is hot rolled, and to give sufficient hardenability by the heat treatment after cold working, by addn. of a trace amount of B to the low alloy steel contg. Cr, and by conducting a specific heat treatment.  
     CONSTITUTION: The boron steel is a low alloy steel of medium or low carbon comprising 0.15W0.40% C, 0.3W1.2% Mn, 0.5W1.5% Cr, <0.10% sol. Al, 0.0003W 0.0050% B, in addn., contg. <0.10% V and/or <0.05% Nb. The steel is soaked at a temp. not lower than 1,000°C, then hot rolled at a draft not smaller than 15, and finished at a temp. 830W950°C to form fine, uniform ferrite-pearlite structure. After hot rolling, fine and uniform structure is formed by the control of cooling rate at 0.3W3.0°c/sec. without increase in bainite structure. The inclusion of B restrains the formation of bainite, forming fine structure of pro-eutectoid ferrite-pearlite, which is excellent in col workability and machinability.

IPC: H03F3/347
Filed: 1984-07-03
Abstract: PURPOSE:To supply an output current corresponding to a plus input signal from the 1st Tr to a load, flowing a current which is a specific multiple of the collector current to the 1st Tr decreasing with a negative input signal from the 2nd Tr to the load, and supplying a current corresponding to the positive and negative input signals to the load by providing the 1st Tr which is connected on an emitter-follower basis and the 2nd Tr which operates according to the collector current of the 1st Tr.

Title: Oxide superconductor
Inventor: SHIMANO TAKASHI
IPC: H01B12/06
Filed: 1987-06-01
Abstract: PURPOSE:To prevent the deterioration of a metal wire by forming an oxide superconductor layer and a stabilized metallic layer in this order at the outer side of a metal wire which furnishes an antiacidprocessed layer over the surface. CONSTITUTION:An oxide superconductor made by covering the outside of a superconductive wire with a good heat-conductive metal is composed of an alkaline earth metal, a rare earth group element, copper, and oxygen, represented by Y-Ba-Cu-O type. For the formation of the oxide superconductive layer, an oxide superconductor paste is spread over the surface of a metal wire which furnishes an antiacid processed layer, and it is sintered and formed in the ambiance including oxygen. In this case, a crack is liable to be generated an the membrane during the sintering if a thick membrane is formed by only one round spreading. But by making the thickness of the paste-spread membrane small, and repeating the process of spreading and sintering several times to thicken the membrane, the oxygen is fed sufficiently to the whole body of the superconductor layer to obtain a good superconductive property. In such a way, the brittleness of the oxide superconductor is overcome and a long wire material can be obtained.

Title: Infrared sensor
Inventor: WATABE YOSHIFUMI
IPC: G01J5/02
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To obtain an infrared sensor by which infrared rays are detected precisely by a method wherein a first pulse signal is input, a second pulse signal which is input in succession to the first pulse signal and whose signal value is smaller than that of the first pulse signal is input and a change in a resistance value during the input of the second pulse signal is measured. SOLUTION: When only a first pulse signal is input, an infrared sensitive resistor generates heat when the first pulse signal is input, and a temperature is raised. When the input of the signal is finished, a temperature drop is started from a point of time when the input of the signal is finished. At a point of time when the input of the first pulse signal is finished, a second pulse signal whose level is lower than that of the first pulse signal is input. Then, the infrared sensitive resistor generates heat so as to raise a temperature when the second pulse signal is input from a point of time when the temperature drop is started after the finish of the input of the first pulse signal. A temperature drop is started from a point of time when the input of the second pulse signal is finished. Consequently, while the second pulse signal is being input in order to measure a change in a resistance value, the heat dissipation of the first pulse signal is overlapped with the heat generation of the second pulse signal, and a temperature change becomes gentle.

Abstract: PROBLEM TO BE SOLVED: To suppress variation of amount of material to feed by feeding a material from each output part at least once to each of plural parts, to which material of almost the same quality is fed by plural output parts. SOLUTION: A liquid-drop 7 is fed (n) times (n>1) to each element part by usign a liquid-drop feeding device 6, having (m) (m>1) pieces of nozzles lining up with almost the same interval as an interval between elements in a row direction. At that time, the liquid-drop 7 is discharged from all of the (m) pieces of nozzle and is fed one by one to each element in (m) lines by scanning them one time. The liquid-drop feeding device 6 is then moved for one element length in the nozzle direction, the liquid-drop 7 is discharged from all of the (m) pieces of nozzles and is fed one by one to each element in the (m) lines by scanning one time. The liquid-drop 7 is fed to each element from the (m) pieces of nozzles (n) times for each by repeating the process. Thereby, the variation of an element resistance can be suppressed without relying on the fine adjustment of an amount to discharge.  Moreover, n>=m>1 is preferable.

Filed: 1977-11-18
Abstract: PURPOSE:To raise the peak of high threshold frequency and form a speaker of a wide frequency range with a simple constitution by providing a reinforcing ring to the connection portion of bobbin and diaphragm. CONSTITUTION:A reinforcing ring 9 is coupled near the root 8 on the inner side of a bobbin 7 in a speaker consisting of a diaphragm 5, diaphragm edge 6 and bobbin 7. In the results of calculations by the finite element method of the case when the reinforcing ring 9 is provided in this way, A, B, C show the sound pressure characteristics of total, diaphragm 5 and edge 6 respectively and D shows the peak of high threshold frequency. In this case, the peak D of the high threshold frequency is produced in the neighborhoo of 40K Hz, which is higher by about 50% than that of the case when no reinforcing ring is provided. Hence, the provision of the reinforcing ring 9 in this way enables the speaker of a wider frequency range to be formed.
