Title: Charging method of raw material into blast furnace
Inventor: JINBO TAKAO
IPC: C21B7/20
Filed: 1982-01-14
Abstract: PURPOSE:To control the position of a distributing chute accurately and to charge the raw materials for the next time by a desired amt. surely into a desired position by detecting the timings for the start and end of charging of the raw materials and the position in the circumferential direction of the distributing chute and deciding the position where charging is completed. CONSTITUTION:Raw materials (m) enter a distributing chute 9 through chutes 17, 11 and are charged into a blast furnace 10. In this state, the starting of passage of the raw materials (m) passing through the inside of a vertical chute 11 and the stopping of the supply are detected with a photodetector 13 when a lower sealing valve 8 opens, and are inputted to an operator 15. The direction of the chute 9 from a reference position is detected with an angle detector 16, and is inputted to the operator 15. From the inputs thereof, the position where charging of each raw material in the circumferential direction of the furnace 10 is decided. In accordance with the results of the decision, signals are fed to driving mechanisms 18, 19 for opening and closing of valves to open gate valves 7 for regulation of flow rate and sealing valves 8 for lower parts so that the position where the charging of the previous time is completed and the position where the next charging is to be started are made coincident. Or if necessary, the next charging is started after the chute 9 is deviated by a prescribed angle.

Title: Photodetector
Inventor: FUJII KAZUTO
IPC: H01L31/14
Filed: 1991-01-19
Abstract: PURPOSE:To eliminate that light to be detected is absorbed by a method wherein the intensity of the light to be detected is detected by utilizing that an electron level is shifted by an optical Stark effect when the light to be detected is incident and that a tunneling current is changed by its shift. CONSTITUTION:When a semiconductor layer of a quantum well structure is irradiated with light, a first level ENa of a well layer 17 is shifted to the lower side and a first level EWa of a well layer 15 and a well layer 19 is shifted to the higher side. As a result, ¦ENa-EWa¦ is reduced, the probability that electrons are tunneled to the well layer 19 through the well layer 17 from the well layer 15 is increased, and an electric current is detected by using an ampere meter 9. Since the Stark shift amount of an electron level is proportional to an optical intensity, the amount of the electric current reflects the optical intensity. The optical intensity can be calculated back from the amount of the electric current.

Title: Conductive modulation type mosfet
Inventor: WATANABE KIMINORI
IPC: H01L29/78
Filed: 1985-01-17
Abstract: PURPOSE:To prevent any latch up phenomenon up to high current regions from occuring by a method wherein the parts not forming source diffused layers are periodically provided in the first conductive type base layers while the width of source diffused layers coming into contact with source electrodes is made 10mum or less. CONSTITUTION:A part of source layers 14 is periodically removed to make the width of source diffused layers 14 coming into contact with source electrodes 17 10mum or less. The length l3 from a point (b) to parts 21 not forming the source diffused layers 14 is reduced less than half of the length of layers 14 so that the hole current at the point (b) in a channel part may flow easier into the parts 21 not forming the source diffused layers 14 than through the parts below the layers 14. Through these procedures, any latch up phenomenon up to high current regions may be prevented from occuring since the resistance in the lateral direction below the source diffused layers 14 may be effectively reduced less than that in any conventional structures.

Abstract: PURPOSE:To output a pulse signal at high speed and also, to output the accurate number of pulse signals by arranging plural devices to generate a pulse with frequency corresponding to pressure by combining so as to be operated by sensing depressing pressure at different parts of a key top. CONSTITUTION:A force from the finger of a user is transmitted to a longitudinal pressure sensor 12 and a lateral pressure sensor 14 by a pressure transmission mechanism 11. The force transmitted to the longitudinal pressure sensor 12 is converted to an electrical signal based on the magnitude of it, and is transmitted to a longitudinal pulse signal generator 13. The longitudinal pulse signal generator 13 generates and outputs a pulse signal at reciprocal speed proportional to the value of a transmitted electrical signal. Similarly, as for a lateral direction, the force transmitted to the lateral pressure sensor 14 is outputted as a lateral pulse signal in proportion to the magnitude of the force. In such a way, it is possible to generate the longitudinal pulse signal and the lateral pulse signal simultaneously based on the force impressed on and the position of the key top.

Title: Position detecting device for annular running body
Inventor: KAJIYAMA SHIGERU
IPC: G01B21/22
Filed: 1982-01-20
Abstract: PURPOSE:To perform the detection of an absolute zero point, restriction of a running range, and check and correction of the moving amount, and the like, by combining the signals from a moving amount detecting sensor and a slant angle sensor of the running body which runs by amount one time on the annular rail in the forward and reverse directions. CONSTITUTION:A driving device 3 is scanned in the forward and reverse directions for some time. Based on the output signal of the slant angle sensor obtained in this range, the right upper position (0 degree) is designated. This position is determined as a base point. Then, the outputs of an encoder 11, which are obtained with the movement of the driving device 3, are counted, and the upper and lower limits of the running range are checked with said moving amount. Then, based on the signal from the slant angle sensor, the corresponding fixed point is judged from the moving amount. The fixed point and the moving amount are compared. When the difference is larger than a specified value, it is judged as abnormal, and the driving device is stopped. The moving amount is corrected to the value of the fixed point. Thus, the moving amount is automatically corrected by the slant angle sensor signal which is obtained at every fixed point.
