Title: Corrosion resistant steel material and its production
Inventor: USUI MASAYOSHI
IPC: C23C10/28
Filed: 1979-10-11
Abstract: PURPOSE:To diffuse Sn or Sn-Cu on steel material surface and improve corrosion resistance by forming an Sn film on the surface of an iron or steel material or Cu- plated iron or steel material, then heating the same to specific temperatures. CONSTITUTION:Sn is electroplated on the surface of an iron or steel product or Cu-plated iron or steel product. Next, it is heated to 770-1,120 deg.C in an atmosphere gas comprising CO, H2, N, etc., after which it is quickly cooled. The heating causes Sn or Sn-Cu to diffuse into the iron or steel material and the solid solution layer of alphaFe or gammaFe is formed depending upon the heating temperatures. The corrosion resistance of the iron or steel material by Sn is considerably improved by the formation of this Sn-Fe or Sn-Cu-Fe solid solution layer.

Title: Device for preventing occurrence of combustion vibration
Inventor: TAKESHITA SHIROU
IPC: F23N5/24
Filed: 1983-07-18
Abstract: PURPOSE:To prevent the occurrence of combustion vibration during ignition at a low temperature time, by a method wherein the inside space of a combustion cylinder combined with a combustion chamber is partitioned by a control plate having a communicating hole which intercommunicates the burner side and the bender side. CONSTITUTION:A burner block 1 is located so that a burner is positioned in a direction extending orthogonal to the direction of axis of a combustion cylinder 3, and high temperature exhaust gas after combustion is forcibly guided downward by means of a communicating hole 10 in a control plate 9 located within a passage in a combustion cylinder 3, and is exhausted to the outside from an exhaust pipe through a bender 4, a flow uniformizing pipe 5, and an exhaust chamber 6. Location of the control plate causes disturbance of a temperature boundary layer formed in the passage, and causes non-uniformization of a reflecting state at the boundary layer of a pressure wave during ignition in which combustion vibration is caused, and this removes the cause of the occurrence of combustion vibration. The control plate 9, positioned in a slanted manner, has a communicating hole 10, formed by a plurality of pores, on the side where the air for circulation in the chamber collides with the outer wall of a combustion chamber 3. This constitution removes the source of the production of a steady wave generated in a combustion cylinder and a communicating passage, which are most related to acoustic resonance of a system holding combustion vibration, and enables to perform efficient heat exchange.

Title: Heating apparatus
Inventor: FUSE NOBORU
IPC: H01L21/22
Filed: 1988-05-27
Abstract: PURPOSE:To increase the heat insulating effect of a heating apparatus and also the cooling effect, improving a static characteristic and a dynamic characteristic, which are opposite to each other, of temperature characteristics of the heating apparatus at the same time, by providing a space layer between heat insulating material layers which insulate the heat from a heater. CONSTITUTION:A space layer 5 is provided between heat insulating material layers 2a and 2b which insulate heat from a heater 1. For this purpose, fluid whose heat insulating effect is relatively excellent, e.g., air, is used as a heat insulating material in the space layer. The space layer is, e.g., a tightly sealed container or an opened container. The space layer can be a vacuum container 5. The apparent heat capacity is made large, and the temperature characteristics of a heating apparatus are improved. When the heating apparatus is heated in the tightly sealed container, new air having a low temperature substitutes for heated air having a high temperature as required. When the temperature is to be decreased, air having a cooling function is made to flow in and circulated. Thus, the temperature decreasing characteristic of the heating apparatus can be improved. In this way, the heating apparatus wherein the temperature characteristics, i.e., the static characteristic and the dynamic characteristic, are improved at the same time is obtained.

Filed: 1978-10-25
Abstract: PURPOSE: To enable the oblique advance of a sheet material to be corrected even if the sheet material conveying passage is sharply bent, by arranging a slip conveyance means between a sheet material feeding means and a resistor roller which corrects the oblique advance of the sheet material.  
     CONSTITUTION: A sheet material 6 is sent-out one by one from a cassette 2 through the revolution of a pick-up roller 7. Then the sheet material 6 reaches a resistor roller 13, guided by guide plates 8 and 9, slip conveyance means 10, and guide plates 11 and 12, and here oblique advance is corrected. In this case, the slip conveyance means 10 is constituted of the roller 21 made of the material having relatively high frictional coefficient such as rubber and the roller 20 rotatable against the shaft 22 and having narrow width in the direction of shaft. Accordingly, when the top end of the sheet material 6 is set in oblique advance into the resistor roller 13, only the part which has not been dashed against the roller 13 of the sheet material can be transferred, and oblique advance can be corrected effectively.

Title: Superilluminescent diode
Inventor: NOGUCHI ETSUO
IPC: H01L33/38
Filed: 1989-05-26
Abstract: PURPOSE:To fully prevent light from returning from an edge side to a light emission section and to fully restrain FP mode oscillation by forming a bending guide active layer which guides light following a linear active layer to a direction which is different from that on an extension axis of the active layer. CONSTITUTION:A linear active layer 14 is formed vertically to a cleavage edge side 21 which becomes a take-out surface of light, and bent at an active layer 15 of a bending guide following the active layer 14 at a radius of curvature R which allows to guide most of light emitted at the linear active layer 14. In a part wherein light is absorbed while being guided, the longer the bending guide active layer 15 is, the more it effects in a state that non-excitation or reverse-bias is applied. In this case, bending loss is extremely little at the radius of curvature R of 3mm or more, and most light is guided and escaped. Effect to restrain FP mode oscillation becomes larger by forming an AR film to the edge side 21 for taking out of light.

Title: Battery type ignition unit
Inventor: NODA TEIZOU
IPC: F02P9/00
Filed: 1984-06-26
Abstract: PURPOSE:To reduce the load of the battery so as to ensure long life of the battery, by connecting a capacitor which has a relatively large capacitance and is accomodated in a heat resistant resin box, to the battery which supplies to the ignition coil, in parallel. CONSTITUTION:A capacitor C having a relatively large capacitance is connected to a battery E which supplies to an ignition coil, in parallel. The energy 1/2CE<2> due to the capacitor C is applied in the same direction as the direction in which the battery E supplies the electricity to the loads (L, R), whereas the energy 1/2LI0<2> due to the inductance L is directed in the opposite direction. Consequently, the energies in a transition condition wherein the point P is switched from ''off'' to ''on'', cancel each other and the load of the battery E can be reduced. Thus, the long life of the battery can be maintained.

Abstract: PURPOSE: To send a PB dial signal as a control signal to a DP dial line while satisfying a prescribed limit for the average level of a low frequency component when a master set receives dial data containing a tone switching signal from a slave set. CONSTITUTION: Assuming that a control part 4 judges a line 3 as a DP dial line A and a master set 1 receives the tone switching signal contained in abbreviated dial data S from a slave set 2, in this case, each time the data S after the second data are first received later, the master set 1 inhibits the transmission of a PB dial signal PB based on the data S and transmits a busy signal to the slave set 2. When the data S after the second data are received again, the master set 1 sends the signal PB based on the data S to the line 3. When the slave 2 receives the busy signal from the master set 1, after the lapse of prescribed time to provide minimum pause for satisfying the limit of the average level, the dial data after the second data are sent to the master set 1 again. Thus, the signal PB can be processed and sent to the line A.
