Title: Anode electrode for molten carbonate fuel cell
Inventor: SHIMIZU KAZUSHI
IPC: H01M4/86
Filed: 1988-06-30
Abstract: PURPOSE:To obtain an anode electrode for molten carbonate fuel cell excellent in electrode activity by specifying the hole rate and average hole diameter in an anode electrode. CONSTITUTION:An electrolytic plate 2 impregnated with a molten salt is supported between an anode electrode 3 and a cathode electrode 4. In this case, when the porosity of the anode electrode 3 is V(%) and the average hole diameter is L(mum), V and L satisfy the schemes I, II, respectively. Thus, the anode electrode receives a sufficient supply of electrolyte from the electrolytic plate, and the supply of a reaction gas is also improved. Hence, the activity of the anode electrode is increased, and an anode electrode having less polarization can be obtained.

Title: Split-phase starting device for motor
Inventor: KAWASHIMA KAMIHITO
IPC: H02K17/08
Filed: 1991-07-03
Abstract: PURPOSE:To prevent the influence of arc,discharges between relay contacts to a positive-temperature coefficient thermistor and heating of the thermistor by a compressor by fitting the case of the thermistor to the surface of a bobbin opposite to a sealed container. CONSTITUTION:A starting relay 8 is fitted to a sealed container 1 by inserting the relay 8 into the airtight terminal 4 of the container 1. This relay 8 is formed by separately assembling a bobbin 11 and the second case 27 for housing a positive-temperature coefficient thermistor. Since the thermistor is fitted apart from the container 1 when a starting device 5 is put in the terminal 4 of the container 1, the influence of the heat of a compressor to the thermistor can be prevented. In addition, since the relay 8 and thermistor are housed in different cases, the thermistor does not receive any influence from arc discharges between relay contacts and the combination of the relay 8 and thermistor can be easily changed.

Title: Token control method and its equipment
Inventor: FUKUOKA TOMOHIRO
IPC: H04L12/40
Filed: 1992-06-22
Abstract: PURPOSE:To allow a token controller to implement execution flow control in response to status of a terminal CPU when plural consecutive tokens transferred from a host CPU or a memory are sequentially implemented. CONSTITUTION:Each token consists of a token code indicating a type of the token and a data field storing data such as a command and a parameter and transferred via a bus 1. Furthermore, a wait token being a kind of tokens storing the execution condition of the token as data of a data field is transferred before each token. When the token is the wait token, a token analysis holding circuit 3 holds the data of the token data field as the execution condition of the succeeding token transferred next to the token. An execution condition discrimination control circuit 5 compares the execution condition with a status and stops the token output to an internal circuit from a queue 2 until such time as the both are coincident.

Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To facilitate the replacement of a photoreceptive drum, a developing device, an intermediate transfer body, and so on, and to prevent degradation in the rigidity of an image forming device main body. SOLUTION: The image forming device main body is provided with a front plate 61 and a rear plate 62, both being flat plates, and, between them, the photoreceptive drum 15, the developing device, and the intermediate-transfer-body unit 50 having the intermediate transfer body 9 are attached so that they are freely detached.

Title: Saw blade
Inventor: KOKADO KOJI
IPC: B23D61/12
Filed: 1987-07-02
Abstract: PURPOSE:To lower cutting resistance so as to smoothly remove a cut chip in order to restrain breakage of a blade, enhancing the cutting performance and accuracy and restraining vibration sound, by forming a straight section in a rake face of a tooth toward the bottom of the tooth at a certain angle to the rake surface so as to space the winding center of a cut chip from the center of the addendum. CONSTITUTION:A rake angle theta1 defined by a line from a point B on a rake surface which is slightly below the addendum end 3 of a saw blade 1 to a perpendicularly descent point C and a line from the point B to a point D forming a predetermined angle, is set. A curve R1 is depicted connecting between a point E on the line extending from the point B to the point D and a bottom point F. Further, a bottom is formed which connects the bottom point F to point G with a straight line, and a curve R2 is depicted connecting between the point G and the point H, and a straight line is depicted connecting between the point H and a point A on the next tooth so as to form a gullet. Accordingly, since the center point K of the curve R1 which is coincident with the winding center of a cutting chip is spaced from the addendum A, the distance by which the chip makes contact with the rake surface is decreased so as to reduce the cutting resistance and a load to the addendum, thereby it is possible to increase the tooth thickness M so as to increase the mass and strength of the tooth.
