Title: Burner
Inventor: OKAMOTO KENYA
IPC: F23C99/00
Filed: 1987-09-11
Abstract: PURPOSE:To improve an effect of reduction of NOx in a low NOx burner utilizing a complete pre-mixing combustion by a method wherein a group of flame holes formed by a flame hole plate and a flame hole partition plate, the flame hole partition plate is projected into a combustion chamber and several counter flames are formed. CONSTITUTION:A combustion chamber 8 is formed by a combustion chamber wall 9 and a combustion chamber outlet 10. The combustion chamber wall 9 is provided with a group 4 of a plurality of flame holes arranged at a substantial constant distance and opposed to each other. Flame holes 5 in the group 4 of the flame holes are formed by bending a thin plate continuously and combining it with a flat plate. A fuel supplying passage 3 is of an elongated cylinderical structure and the group 4 of the flame holes having several flame holes 5 is constituted at the combustion chamber 8 by a flame hole plate 6 and a flame hole partition plate 7 projected toward the combustion chamber 8. When mixture gas fed from the flame holes 5 into the combustion chamber 8 is ignited, a flame is formed. The flame hole partition plate 7 is red heated by the flame due to its projection from the flame holes 5, resulting in that a thermal radiation is increased. In order to stabilize the combustion more, it is sufficient to make some punched holes in the projection of the partition wall 7.

Title: Looped transmission system
Inventor: KUBO AKIHIKO
Filed: 1985-10-15
Abstract: PURPOSE:To easily change the ratio of a synchronizing signal area to an asynchronous signal area, by setting either one of synchronous and asynchronous in addition to transmission-able, transmitting, and neutral in control areas of time-divided plural slots moving round an annular transmission line. CONSTITUTION:A frame 31 is constituted of plural slots 23 and either one of synchronous and asynchronous is set in addition to transmission-able, transmitting, and neutral in an access controlling area 12 as control information. When a synchronizing signal is transmitted, a transmission equipment 32 requests an assignment of a synchronous slot to a management device 33. The management device 33 assigns a vacant slot 23 where synchronism is established to the access controlling area 12 after retrieval. When synchronous communication is terminated, the transmitter 32 releases the used slot. An asynchronous signal is also transmitted in the same procedure. Therefore, the overall communication efficiency can be improved by easily changing the ratio of the control area of synchronous communication to that of asynchronous communication.

Title: Dry manufacturing process of hydrogen storage alloy electrode
Inventor: HAYASHIDA HIROTAKA
IPC: H01M4/38
Filed: 1988-09-13
Abstract: PURPOSE:To increase both the hydrogen gas absorbing ability and the electrode capacity by the following process: Specified amounts of powder of fluorine resin and powder of hydrogen storage alloy relative to the weight of an electrode are mixed under the influence of shearing stress to make a cotton-like mixture which is placed on an electricity collector and formed. CONSTITUTION:When powder of hydrogen storage alloy and a specified amount of powder of fluorine resin are mixed together by means of a mixer such as a cutter mill under the influence of shearing stress, an aggregate of single strands is produced in which the fluorine resin powder has turned into slender single strands intertwined in a condition of cotton. The slender single strands are intertwined in a cotton-like condition to the extent that the alloy powder does not fall off. As a result, a cotton- like mixture is obtained by mixing the hydrogen storage alloy powder and the fluorine resin powder under the shearing stress, with the mixture comprising the aggregate of the strand-like fluorine resin and the alloy powder retained in the aggregate. This mixture is placed on a collector as an electricity conducting base body and formed to obtain an electrode. The amount of the fluorine resin powder to be added herein is ranged within 0.5-5.0% of the weight of the electrode.

Filed: 1989-09-06
Abstract: PURPOSE:To largely improve resistance against breakdown when surge is applied by a method wherein either an anode or a cathode of a diode is formed in an Si substrate via a connection hole formed on an insulating film. CONSTITUTION:In second diodes 40 and 41 constituting an input protection circuit, pn-junction is formed vertically while the junction area is determined by size of a connection hole (h) formed on an insulating film. Thus the junction area which has been able to be obtained by thickness of a thin film conventionally can be increased so that rise in current density can be suppressed. In addition since an end of a protective diode is formed in an Si substrate and a heating part is an interface between the Si substrate and an Si thin film, heat radiation property is largely improved resulting in remarkable improvement in resistance against breakdown when surge is applied.
