Title: Method for annealing warm forging
Inventor: HANAI AKIMOTO
IPC: C21D1/26
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To save the energy, and to suppress the raise in the cost by putting warm forged stocks in a heat insulation basket one by one, and gradually cooling them. SOLUTION: A heat insulation basket 10 contains a forged stock carrying port 6 in its center, and a lid 5 having a heat insulation material 7 inside thereof. A warm forged stock 20 is heated to a specified temperature, and forged, and also heated in the forging. Thus, air enters or is discharged through the forged stock carrying port 6, and the warm forged stock 20 can be naturally cooled, but they are put in the heat insulation basket 10 one by one, the temperature in the heat insulation basket 10 is not dropped, and the warm forged stocks 20 are gradually cooled, that is, annealed. Since the cooling speed of the warm forged stock 20 in the heat insulation basket 10 is slow, the growth of the ferrite is promoted though the structure is the pearlite the same as that in the naturally cooled condition, and the hardness is not increased.

Abstract: PURPOSE:To raise a breakdown strength and to reduce a collector resistance, by forming a collector electrode leading layer by utilizing an impurity diffusion conducted into a polysilicon for forming a gate electrode of a CMOS FET to form a resistance of the polysilicon layer. CONSTITUTION:An opening 28 is formed by first removing by photolithoetching a polysilicon layer 27 and then removing an oxide film 26 of a region from which the layer 27 is removed with fluoric acid series solution with the layer 27 as a mask. Then, it is formed by removing th film 26 of the region from which the layer 27 is removed. Thereafter, a phosphorus high concentration diffusion for reducing the resistance value of the layer 27 is executed for the layer 27 in this state. Then, when the phosphorus is doped in the layer 27, the phosphorus is simultaneously diffused in the part of the N-P-N transistor forming region of an epitaxial layer 23 through the opening 28, and a high concentration collector electrode leading layer 29 is formed. Thus, the collector resistance of the N-P-N transistor can be reduced without increasing the number of steps.

IPC: B65D88/70
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a powder storage tank in which a bag filter can be formed smaller and the discharge of stored powder can be carried out efficiently. SOLUTION: A fluid mixed with cement and air is received from a transfer pipe 13 by a case 15. A bending section B1 is provided in the transfer pipe 13, and the fluid can be received on a discharge section in the vicinity of a lateral screw conveyor 19A in the case 15. When cement is accumulated in the case 15, the most part of cement discharged out of an end T1 is absorbed into an accumulated layer by the arrangement. The most part of air passed through the accumulated layer, therefore, becomes clean air almost not containing the cement, and the discharged air can be cleaned sufficiently by a small filter. Also the fluid can discharged in the right downward direction on the end T1 to prevent the formation of a bridge on the discharge section in the vicinity of the horizontal screw conveyor 19A.

Abstract: PURPOSE:To obtain such a hard copy that part of an original image is erased optionally by providing a means which erasing part of the original image in a desired area in an image forming process with an erasure signal inputted according to a marker position. CONSTITUTION:When the erasure signal is inputted from a keyboard 3a during exposure scanning, the erasure signal is transferred to a controller 35 through an I/O port 34. A delay circuit 38 is provided in the controller 35 and a clock start signal from an image forming means 1 and said erasure signal are inputted through an AND gate 39. In this case, there is a delay of time (t) until the exposure point when the erasure signal is inputted reaches a black point as the irradiation position of a blank lamp. The delay circuit 38 delays a blank turn- on signal by said delay time and outputs it to the control circuit 8 of the image forming means 1 to turn on the blank lamp. Consequently, part of a latent image on a photosensitive body corresponding to where the erasure signal is inputted from the keyboard 3a is discharged to erase the latent image, thereby obtaining a partially removed copy.

Title: Drive shaft coupling and discoupling device in four wheel drive vehicle
Inventor: ONODERA TAKAYOSHI
IPC: F16H48/30
Filed: 1984-11-13
Abstract: PURPOSE:To enhance the durability of coupling sections of a connecting rod and a second coupling member, by locking both ends of a compression spring which urges the second coupling member, to the latter always excepting the time when the connecting rod is moved. CONSTITUTION:One end of a compression spring 37 in a coupling mechanism 30a is locked direct to a coupling rod 32 while the other end thereof is locked indirect to the coupling rod 32 through a spring seat 38, a plate 39 and a first snap ring 32b, and therefore, a compression sring 37 does not yet exert its urging force to a connecting rod 36. As a result, even if a differential gear unit is operated upon coupling of both drive shafts so that a relative rotation is effected between the coupling rod 3 and the connecting rod 36, no friction forces caused by the urging force of the compression spring 37 are effected between each component parts in the coupling mechanism 30a, and it is possible to enhance the durability of the mechanism 30a.

Abstract: PURPOSE:To improve the follow-up performance of fuel pressure control by previously using the deviation between a fuel cell real load and erquire value in the fuel supply control to a fuel processing device with the fuel supplied to a fuel cell is processed. CONSTITUTION:A fuel pressure adjusting valve 12 provided at the inlet of a reformer 11A is controlled in such a way that the inlet pressure of a fuel flow adjusting valve 9 nears the set value. At the time of load increasing, required fuel flow increases and the inlet pressure of the fuel flow. adjusting valve 9 lowers, thereby the fuel quantity to be supplied to a fuel processing device 11 is previously increased based on the deviation between a required load value from a cell output setter 30 and a real load from from a cell output detector 26. At the time of load lowering, the required fuel quantity decreases and the inlet pressure of the fuel flow adjusting valve 9 increases thereby the fuel quantity to be supplied to the fuel processing device 11 is previously decreased based on the deviation between the required load value and the real load. Thereby,it is possible to lower the pressure change of the fuel according to the load change and to ensure the fuel cell power generating plant with stability and follow-up performance.

IPC: B65G47/49
Filed: 1985-10-24
Abstract: PURPOSE:To prevent bobbins of different brands from mixing in by sticking a label printed with a brand indicating part and a brand code of a yarn on a pirn of which winding has been finished and by discriminating later brands by means of image processing. CONSTITUTION:On the upper face of pirn 1 of which winding is finished is stuck a label 3 printed with a brand and a brand code. In an image processing device just before shipment, the pirn 1 is moved on a conveyer 7 to read the label indications by means of a camera 4 of the image processing device and the image of a brand code read is compared with that stored beforehand in the image processing device 5. The result of judgement is transmitted to a control 6 of the conveyer 7 and, in case of a different brand, the conveyer 7 is stopped so that the wrong brand can be detected. This makes it possible to judge mixing of different brands automatically to cope with production involving multiple product varieties.

The lower end of the grating 4 is brought into weak contact with a reference surface 5, lifted by the insertion of an object (sheet) 6 to be detected, and the angle of the grating 4 is varied. The variation of the angle of the grating 4 is detected as the angle change of the incident light at the photodetector 2, thereby measuring the thickness of the object 6 to be detected. In this case, as the photodetector 2, a photodiode PD is used, and the angle change of the incident light from the change of the light intensity is obtained.
