Title: Unified type methanol reforming equipment for fuel cell
Inventor: UEMATSU KENGO
IPC: B01J19/00
Filed: 1986-01-16
Abstract: PURPOSE:To improve efficiency and enable miniaturization and simplification by containing each device for reforming reaction, heat transfer, cooling and water separation in an unifying container. CONSTITUTION:Raw material comes from a row material nozzle 9 into a reaction tube group 11 where reforming catalyst 12 is filled and methanol reforming reaction arises. On the other hand, high temperature combustion gas coming in from a combustion gas nozzle 13 supplies reaction heat and goes out of an exhaust gas nozzle 14. Reformed gas produced enters a heat transfer tube group 16 partitioned by a mid-tube plate 15. As the heat transfer mode here becomes convection heat transfer, buffles 18 supported by spacers 17 are equipped at the inner side of the heat transfer tube group 16 in order to improve the heat transfer performance furthermore. On the other hand, dehydrated gas coming out of a water separating part 19 is supplied from a dehydrated gas nozzle 20 to the outside of the heat transfer tube group 16, goes out of an anode supply gas nozzle 21 after exchanging heat and enters the anode part 7 of the fuel cell. The reversed gas is collected in the demister 26 of the water separating part 19 and supplied to the dehydrated gas nozzle 20.

Inventor: HARADA YASUO
IPC: F02M25/07
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of exhaust emission by inhibiting execution of feed back control in the case where a parameter changed according to an operating condition of an EGR valve is not in a control target region, or in the case where the parameter is in the control target region at the time of EGR feed back control. SOLUTION: During operation of an internal combustion engine 10, in an ECU 12 a command injection rate of fuel is calculated on the basis of a period operating condition, and fuel is forcibly supplied from a fuel injection pump 14 to a fuel injection valve 38 in a timing which is set on the basis on a relation between engine rotating speed and the command injection rate. A tolerance of an injection rate in relation to the command injection rate is read out from a map, and a target opening of an EGR valve 64 is found out according to a value obtained by adding and subtracting the tolerance of the injection rate on/from the command injection rate.  In the case where a real opening of the EGR valve 64 is in an opening region according to an injection rate region on the basis of the tolerance between the command injection rate of fuel and the injection rate, the EGR valve 64 is feed back-controlled. In the case where it is not in the opening region, feed back control is inhibited.

Abstract: PURPOSE:To improve tight-adhesiveness between a board and a device and realize high integrity by a method wherein a metallized layer composed of mixed layers is provided on the AlN ceramics board and the device is soldered to the metallized layer with metal having a specific melting point. CONSTITUTION:A metallized layer 21 composed of mixed layers of AlN ceramics and Ni and Cu is formed on an AlN ceramics board 1. Then a silicon IC chip 23 is soldered to the layer 21 with metal having a relatively low melting point not higher than 560 deg.C. Under the temperature not higher than 560 deg.C, the difference in thermal expansion between the ceramics and the metal in the layer 21 can be absorbed by the mixed layers, so that the peeling-off of the layer 21 can be avoided. Moreover, as the AlN ceramics has a high thermal conductivity, even if the layer 21 and the chip 23 generate heat during the operation, the heat is discharged satisfactorily. With this constitution, the peeling-off of the metallized layer can be avoided.

Title: Semiconductor laser
Inventor: NAGAI SEIICHI
IPC: H01S5/00
Filed: 1988-01-14
Abstract: PURPOSE:To decrease a reduction in an optical output due to temperature rise and to obtain the output having a predetermined intensity at the time of driving a pulse by increasing the end face reflectivity for outputting a laser beam to be mainly used as compared with that of the other end face. CONSTITUTION:The reflectivity of a front end face for outputting a laser beam to be mainly used is increased over that of a rear end face. Accordingly, optical output P current I characteristic for the light emitted from the front end face becomes as shown in fig. a, and optical output P - current I characteristic for the light emitted from the rear end face becomes as shown in Fig. b. Generally, the light emitted from the front end face having high reflectivity becomes lower in efficiency than that from the rear end face. Accordingly, even if the temperature of an active layer is raised by the conduction of a pulse driving current I of a semiconductor laser, a reduction in the optical output P can be reduced as designated by an arrow due to its low efficiency. thus, the variation in the optical output can be eliminated.

Abstract: PURPOSE:To improve the S/N, by amplifying differentially the output of an original reader, then integrating the output signal obtained by said amplification. CONSTITUTION:A signal containing an optical signal and noises mixed up and a signal of only noise are delivered alternately to signal lines 12a and 12b of an original reader. The signals on these lines 12a and 12b are supplied to a differential amplifier 14, and an output containing a small level of noise component is obtained at an output 15. This output 15 is fed to an input 19 and inverted by an inverting amplifier 16. Then both inverted and non-inverted signals are extracted with proper timing to an output 18 by a switch 17. The signals of the output 18 are integrated by an integrator 20, and the electric charge stored in a capacitor 25 is discharged with each fixed period by an MOS transistor TR21. The noise generated in both positive and negative directions is eliminated each other with the integration of the integrator 20. Then the electric  charge stored in the capacitor 25 corresponds only to an optical signal. Therefore only the optical signal is obtained at an output 24 by amplifying 23 the  pulse obtained when the TRT21 discharges.

Abstract: PURPOSE:To improve a noise resistant character, to reduce a displaying space, and to realize a long distance operation by turning on/off a light from a light source by means of a liquid crystal shutter, transmitting it by means of an optical fiber cable to be displied. CONSTITUTION:Display information prepared by a control signal circuit 1 is transmitted through a wire 2 to a liquid crystal shutter 6. The liquid crystal shutter 6 interrupts the light form a light source 3 when an electric field is applied, and the light from the light source 3 is transmitted by the shutter 6 when the electric field is not applied. In such a way, the liquid crystal shutter 6 works as, so to speak, a switch or a shutter to control the light, and even when the light source 3 is single, many signals can be controlled by increasing the number of picture elements 6a. The light to be controlled is transmitted through an optical fiber 7 and displayed on a screen 4. Thus, the noise resistant character can be improved, a transmission distance can be made into a long distance, and since the optical fiber 7 is fine and does not occupy a space, the display can be realized by the small screen.

Abstract: PROBLEM TO BE SOLVED: To minimize the difference of boundary pixels between actual images by estimating a conversion coefficient that is lost at the time of quantization and adding an estimated signal to an original signal that is undergone inverse conversion. SOLUTION: A correction coefficient calculating part 31 calculates a correction coefficient by inputting an original video signal Fq (x, y) which is undergone inverse conversion and a correction coefficient selection signal.

A correction controlling part 33 inputs the original video signal Fq (x, y) that is undergone inverse conversion and a correction boundary value and outputs the correction coefficient to the parts 31 and 32. A selecting part 34 selectively outputs the correction value that is calculated by the part 32 in accordance with a correction control signal.  Further, an adding part 35 adds the signal Fq (x, y) that is undergone inverse conversion to an output signal of the part 34 and outputs a video signal f' (x, y) that is performed post-processing.
