Title: Delivery tube of fluid layer device
Inventor: OGIYAMA KENICHI
IPC: B65G53/52
Filed: 1985-03-22
Abstract: PURPOSE:To release blockable of tube easily, by making the length of a horizontal tube portion larger than a size determined from the inner diameter of the tube and an anble of repose depending on the fluid medium in a delivery tube for particle coal air flow delivery to a fluid floor boiler. CONSTITUTION:The length L of an almost horizontal portion 15 from a vertical tube 6 in a distributor (not shown in the figure) to a skew tube 17 in a delivery tube 12 is made larger than the size l which is determined from the inner diameter D of the tube 12 and an angle of repose alpha depending on the fluid medium. In such a composition, ever though an accumulation of particle coal 8 is generated within the skew tube 17 and the fluid medium 9 flows backward toward the vertical tube 16, a space 18 is produced between the vertical tube 16 and the skew tube 17, causing to produce no accumulation of the fluid medium 9 over the particle coal 8, to prevent the expansion of blockade, and to release the blockade by a normal air pressure. Thus, the blockade is easily released and the operation is stabilized.

Title: Oscillation-proof support device for impeller
Inventor: KONDOU FUMIO
IPC: F04D29/28
Filed: 1981-04-21
Abstract: PURPOSE:To eliminate the creep deformation, etc. and prevent unbalanced oscillations by supporting stationary shafts provided at both ends of an impeller for oscillation-proof construction by use of bearings and oscillation-proof gums and connect them to a shaft on a motor side with a flexible joint. CONSTITUTION:A stationary shaft 4 on the left end is supported by a main body (not shown in the figure) with a bearing 9 and an oscillation-proof gum 10 for oscillation-proof construction, and the middle of a stationry shaft 15 on the right end is also supported by the main body with a bearing 16 and an oscillation- proof gum 17 for oscillation-proof construction. In addition, the tip of the shaft 15 on the right end and the tip of a shaft 13 of a motor 12 fitted to the main body not shown in the figure through an oscillation-proof gum 11 are connected together through a flexible joint 18. Thereby, the eccentricity between an impeller 2 and the motor 12 can be absorbed by the flexible joint 18, and unbalanced oscillations can be eliminated because the impeller 2 itself is supported by the main body for oscillation-proof construction by use of the bearings 9, 16 and the oscillation-proof gums 10, 17.

Title: Device and method for receiving data
Inventor: YUZAWA KEIJI
IPC: H04N21/433
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent the incomplete state of a program from being continued because of adverse reception conditions in the case of downloading program data through broadcast waves. SOLUTION: When new program information is detected, a C/N value is observed (step 4). It is determined whether the observed C/N value is higher than a specified value or not (step S5) and when it is higher' than the specified value, a program for download control is executed (step S6). It is discriminated whether download processing is finished or not (step S7) and the download processing is continued until the end of download processing. Since the download processing is executed after confirming the C/N is satisfactory, danger in the interruption of download caused by the adverse reception conditions in the middle of download processing can be avoided.

Abstract: PURPOSE: To obviate disconnection on account of thermal impact, vibrations, etc. by thermally calking a sheath pipe part first then the insulation pipe part containing a thermistor element at the time of staking the unit contained in a case from the outside of the case.  
     CONSTITUTION: In the sensor comprising providing an insulation pipe 9 such as of alumina ceramics or the like making contact to the end face of a stainless sheath pipe 3 on the outside of a thermistor element 1 connected to the sheath pipe 3, filling inorganic powder 10 such as of alumina or the like between the pipe 9 and element 1 and containing the entire part of these in a case 11 of stainless steel, the part of the case lower than its flange 12 is heated and the case 11 is calked B while the pipe 9 is being let to contact the bottom of the case 11, following to which the case is calked A while being heated in the similar manner. Here, the case 11 is calked B while its end is being heated and therefore it shrinks larger than the pipe 9 at room temperature. This causes compressive stress to be applied in the axial direction of the pipe 9. This compressive force becomes zero only when the case reaches the heating temperature in the next calking A and therefore the disconnection of the platinum electrode wire of the element 1 does not occur.

Abstract: PURPOSE: To prevent deterioration of resolution or the like and to detect a replacement period of an exposure lamp by revising an amplification factor in response to a signal obtained by A/D-converting a reflected light when a light emission position of a read object is opposite to a reference board. CONSTITUTION: At application of power, a control section 101 drives a mechanism control section 105 and when a carriage provided with a reflector reflecting a light from an exposure lamp 25 is moved to a position opposite to a center of a white reference board, the exposure lamp 25 is lighted. After lighting for a prescribed time, the white reference board is read by one line in the main scanning direction and a peak of the line is detected, and when the peak level is smaller than the setting level, an amplification factor of an amplifier of an image processing unit 106 is increased by one step. Then the comparison between the peak level and the setting value is repeated to set a gain of the amplifier suitable for a reference signal of an A/D converter.  Then the relation between the reference signal of the A/D converter and the gain of the amplifier is made proper to prevent deterioration in the resolution or loss of high density.
