Title: Carbonization oven
Inventor: KATAYAMA KIICHIRO
IPC: C10B41/08
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency and productivity of a carbonization oven and the yield of charcoal. SOLUTION: A burner 28 is installed at the lower part of a metal-made oven body 26, and above the burner 28 are installed an equalizing member 29 and a material basket 30. The first valve 31 for controlling the flow rate of air and an inert gas blowing-in means 38 are installed at the lower part of the oven, and the second valve 33 for controlling the flow rate of an exhaust gas is installed at the upper part. To the lid 27 of the oven body 26 is connected an exhaust duct 34 equipped with an opening and closing means 35 and a cooling means 36. Volatile components are lead to the duct 34, cooled to be liquefied, and recovered. Carbonization reaction proceeds by closing the means 35 and by controlling the flow rates of air and the exhaust gas by valve operations.  Air introduced into the oven body 26 is evenly distributed by passing it through the equalizing member 29, thus causing the carbonization reaction to proceed homogeneously and preventing uneven carbonization. The recovery of liquids and the carbonization can be conducted with the same oven by switching the opening and closing means 35. The metal-made oven body and the blowing-in of an inert gas increase the cooling velocity.

Abstract: PURPOSE:To realize miniaturization at the time of making the transfer speed converter and the FIFO of data into integration by using a synchronous single port memory. CONSTITUTION:Serial data with a frequency (a) is stored in the single port memory 1. A serial-parallel converter 2 is operated with the frequency (a), and a parallel-serial converter 3 inputs the data of (n) bits outputted from the serial-parallel converter 2, and sets a flag 4. Furthermore, the data of (n) bits is outputted bit by bit sequentially with a frequency (b). A readout signal generating device 5 generates a pulse synchronized with a clock of frequency (a) only when the flag 4 is set, and an address generating device 6 sends a readout address to the memory 1 synchronizing with the output signal of the device 5. Also, to perform a write operation on the memory 1 with the frequency (a) and a readout operation with the frequency (a) alternately, it is performed by setting the frequency of the clock to be supplied to the memory 1 at 2a, that is a doubled frequency and performing read-in and write alternately.

Title: Alignment detecting method
Inventor: NAKANO TAKAHIRO
IPC: G03F9/00
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To compensate for ununiformity of light flux density accompanying the deflection of optical path by picking up both mask alignment mark and work alignment mark with a camera while irradiating the picking-up area with the scattering beam. SOLUTION: The scattering beam is incident to the mask alignment mark 1a and work alignment mark 4 at the picking-up position and also lights the range sufficiently wider than the regions of the mask alignment mark 1a and the work alignment mark 4. In this case, the lighting beam is incident to the photosensitive material film 3a at the position of the work alignment mark 4 from every angle. Thereby, even if the light incident part of the photosensitive material film 3a is recessed, the light is refracted in every angle when the light passes the recess of the photosensitive material film 3a. Thereby, the density of light flux that is incident to a CCD camera is almost uniformed, except for the part corresponding to the mask alignment mark 1a.

Abstract: PURPOSE: To enable to accomplish the metering of main fuel normally by a method wherein a bypass, bypassing the main fuel metering part, is provided so as to be able to discharge vapor bubbles generated in high temperature fuel therefrom.  
     CONSTITUTION: When the temperature of the fuel in a float chamber 15 turns to be high during engine running, the evaporation of the fuel occurs to generate vapor bubbles in the fuel liquid and the fuel containing bubbles therein flows to a main fuel jet 8. On the other hand, at this time, the negative pressure of the bypass 10 is kept in the state that the fuel in a main fuel passage 9 does not flow in a negaive pressure passage 11 and at the same time the air in an air passage 12 does not flow back to said passage 9 by utilizing the negative pressure at a venturi 6 and properly adjusting the throttles of a negative pressure jet 13 and an air jet 14. As a result, the bubbles in the fuel arrived just before the jet 8 does not long stagnate there in being sucked out through the bypass 10 and the negative pressure passage 11.
