Abstract: PURPOSE: To produce a corrugated radiator having the oil way width corresponding to wave height and improve the degree of freedom of heat design by crushing heat radiating ribs with a male die and a lower die of which the thickness is changed stepwise according to the wave height of said ribs.  
     CONSTITUTION: A corrugated radiator 2 formed to a wave shape of a wave height H is carried in by a conveyor 8, and a lower die 10 ascends in the heat radiation rib by the size having been set in the control system of a lower die driving device. A male die 9 is inserted between the heat radiating ribs, and upon completion of the ascending of the lower die 10, it crushes the end part 3 of the heat radiating ribs. In the crushing process, the oil way width near the root part 17 of the ribs is regulated to the thickness of the die 10 to the size which is the thickness B of the corresponding parts. Upon completion of the crushing of the radiating ribs, the die 9 and the die 10 retreat to the home positions, and the radiator 2 is fed forward by  one wave. Again the same operation is repeated in the positions of the die 9 and the  die 10, whereby the end parts 3 of the ribs are successively crushed. The crushed  end parts 3 are welded in the next process, whereby the corrugated radiator 2 is obtained.

IPC: H01L29/68
Filed: 1988-02-23
Abstract: PURPOSE:To reduce base resistance and improve breakdown strength between C and B, by adjusting the doped amount of a base and causing a difference in prescribed energy levels to be around or above the height of a collector barrier, and by installing a no-added spacer layer between base and collector barriers. CONSTITUTION:An n-type InGaAs base thin layer 9 is provided on an InP substrate 1 through an n<+>-type InGaAs collector 2, an i-type InAlGaAs 3, an i-type InGaAs spacer 8. An i-type InAlAs 5 are put on the thin film layer 9. Assume that the amount of doping to a composition of the base layer 9 is 9X10<18>cm<-3>. In such a case, when a thermoelectron transistor is operated, Fermi levels EF of the base 9 and spacer 8 are shown as chain lines I. In view of the doped amount in the base 9, EC-EF of the base is 0.39eV and it is higher than the height of a collector barrier:  E=0.27eV which is obtained by the spacer 8 and yet, sheet resistance exceedingly decreases. The spacer 8 belongs to an i-type and when EC-EF=0.01eV, it is smaller than  EC. Thus, breakdown strength between C and B can be improved.

Title: Binarization conversion circuit
Inventor: KAWAKITA HARUO
IPC: G01P3/481
Filed: 1994-03-10
Abstract: PURPOSE:To prevent inability of outputting a binarized signal from occuring as caused by failure in computing a threshold with a binary coding conversion circuit or abnormality of the binarized signal as caused by abnormality in the threshold. CONSTITUTION:When a voltage rises, a power only resetting circuit 53k gives POR= '0' for a specified time, a PB terminal moves to '0' and with an SL signal to '0', an S terminal moves to '0'. As a result, a latch hysteresis selection circuit 53i outputs a value Hl preset to a hysteresis computation circuit 53f. When a difference Sn between an extermal value and the current value exceed a hysteresis value H1, the computation circuit 53f outputs a latch signal to an output latch circuit 53g or the like. As a latch signal is outputted from the hysteresis computation circuit 53f, an output latch circuit 53g outputs a high or low level signal Vout based on the indication of an increase/decrease judging signal Sn (MSB). Thus, the hysteresis range H1 is set immediately when a power source is turned ON thereby enabling immediate operation of a comparator.

IPC: G06F17/30
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To inexpensively and also highly reliably perform information providing service to a user in a short response time. SOLUTION: When an information retrieval request A=(a+b+c+d+e+f) exists from a user's terminal 4A of a slave system 3, a retrieval type generating part 9 decides whether only information classes which are stored in a slave system are enough to meet the user's request or a master system 1 is further needed to be retrieved by checking an information management table 10. When the slave system is not able to satisfy, a retrieval expression A= (f+ not (a+ b+c+d+e)) which retrieves information classes f that do not exist in the slave system in the master system is created and sent to the system 1. The system 1 retrieves an information storing part 6 by using the retrieval and sends retrieval result information to the slave system 3.  This is added to an information storing part 8 of the system 3, and retrieval result information that is separately retrieved through A=(a+b+c+d+e) within the slave system with retrieval result information which is retrieved by the master system added is returned to the user, i.e., the terminal 4A. After that, an information management part 11 additionally rewrites information classes f on the table 10.

Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To perform optical etching the entire surface of a substrate, without relying upon a designed dimension by uniformly exiting or raising the temperature of the entire surface and, at the same time, to control the temperature of the substrate at a high speed by utilizing a feature of surface waves in that the wavelength property of the waves can be neglected as electromagnetic waves by guiding infrared rays into the substrate, so that the substrate itself may become an infrared-ray source due to infrared surface waves being generated by the infrared rays. SOLUTION: When infrared rays are made incident to a substrate 3 in a state in which the rays are not totally reflected by the surface of the substrate by arranging a coupling prism 2, so that the prism 2 comes into contact with the substrate 3 or shaving the end of the substrate 3 and the infrared rays are guided into the substrate 3, infrared surface waves are generated on the surface of the substrate 3 and the substrate 3 itself becomes an infrared-ray source. In addition, the temperature of the substrate 3 can be controlled precisely at a high speed, when the infrared-ray output of the substrate is adjusted by using a substrate temperature measuring instrument and a controller.
