IPC: F28B9/08
Filed: 1992-05-20
Abstract: PURPOSE:To prevent a cooling tower from being damaged by a method wherein a collecting means for collecting drain water dispersed from an upper surface of a bottom plate and guiding it downwardly is arranged near a bottom plate of a communicating barrel in a system in which barrel parts of at least two condensing devices are in communication with each other through a connecting barrel. CONSTITUTION:In a condensing device in which barrels of two condensing units communicate with and are connected to each other through a communicating barrel 20 having an opening above a pipe bundle of each of condensing units, steam Fa discharged from a turbine flowed into an upper part of the condensing unit is flowed downwardly, cooled while passing through a group of cooling pipes and condensed. In this case, a louver 22 acting as a collecting means for collecting drain water dispered from an upper surface of a bottom plate and feeding it downwardly is arranged near the bottom plate of the communicating barrel 20. This louver 22 is arranged over an entire region of the opening of the communicating barrel 20 and further welded and fixed to reinforcing ribs 23 of the barrel of the condensing units arranged along a wall surface 21 of a barrel part of the condensing unit. With such an arrangement, liquid droplets dispersed are prevented from being directly struck against the cooling pipe and damage of the cooling pipe is prevented.

Title: Bias eliminating device
Inventor: KANEKO YOSHIO
IPC: H03M1/10
Filed: 1985-06-10
Abstract: PURPOSE:To vary freely the gain of an A/D converter by inputting an analog input signal from a sensor after deciding a bias data for the share of one period so as to eliminate a bias component. CONSTITUTION:The bias data by one period is set to the 1st memory 3 at first. Then the input to a solid-state image pickup element is reduced to '0' and an analog input signal (a) being a sensor output is inputted to a non- inverting terminal of an analog subtractor 1. On the other hand, an analog data converted by a D/A converter 5 from the bias data stored in the memory 3 is inputted to an inverting terminal and the bias component data is subtracted from the signal (a). The result is converted into a digital signal by an A/D converter 2 and stored in the 2nd memory 7. The bias data in the memory 3 corresponding to the value stored in the memory 7 is corrected. Then the data in the memory 7 is zeroed entirely by repeating the operation above. The A/D converting value of the signal (a) eliminated from the bias component is obtained from the converter 2.

Title: Magnetic recording medium and its production
Inventor: TAKAYAMA TAKAHIRO
IPC: G11B5/708
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To improve surface property, to attain stable and fast application of a magnetic coating material having high characteristics and to decrease the production cost by incorporating a titanate coupling agent into a lower magnetic layer of a laminar magnetic layer having a two-layer structure. SOLUTION: Coating characteristics to obtain good surface roughness are more required for the lower magnetic layer than the durability of the coating film. By adding a titanate coupling agent into the lower magnetic layer, coupling groups (hydrophilic groups) in the molecule are adsorbed to the surface of the magnetic powder, while hydrophobic groups have good affinity with the binder to fill the space among magnetic powder particles with the binder. Thus, the coupling agent acts as a dispersant to improve the dispersibility of the magnetic powder. The amt. of the titanate coupling agent is preferably 0.5 to 5 pts.wt. to 100 pts.wt. of the magnetic powder. The titanate coupling agent is expressed by the general formula, wherein an org. functional group. X represents carboxyl or its ester groups, phosphite groups, pyrophosphate groups, amino groups, etc.

Title: Cut sheet conveying device for printing device
Inventor: YOSHIMIZU TOMOMI
IPC: G03G15/00
Filed: 1988-05-25
Abstract: PURPOSE:To prevent the damage of a sheet by means of a roller claw through application of a tension on a cut sheet under conveyance and to improve quality, by a method wherein a roller situated on the outlet side of a sheet conveyance passage is rotated at a peripheral velocity higher than that of a roller located on the inlet side thereof. CONSTITUTION:In a state 6 right after a cut sheet tip 9a is fed from a discharge part roller 2, a cut sheet 9 is temporarily conveyed in a slacked state, but a roller 2 is rotated at a peripheral velocity higher than that of a turn-over part roller 1. Thereby, a running distance on the tip 9a side is increased by means of a difference in a speed therebetween, and the slack of the cut sheet 9 is reduced gradually. Under a state 7 right before a cut sheet rear end 9b is fed from a roller 1, the cut sheet 9 is brought into a state to be stretched along a paper guide 3, and a specified tension is applied on the cut sheet 9. Further, when the rear end 9b is brought into a state 8 in which it is fed from the roller 1, the cut sheet 9 is released from tension and dropped. However, since the sheet does not make contact with the roller 1, the rear end 9b is prevented from being damaged by the claw of a turnover roller, and a printed product of high quality is produced.

Abstract: PURPOSE:To stabilize a joining stage by bringing a jig into contact with the joining region of an electrode terminal and impressing ultrasonic waves to the jig to remove the contaminated layer on the surface thereof, then joining the electrode terminal and a connecting conductor. CONSTITUTION:The surface treating jig 9 is brought into contact with the electrode terminal 3 and is pressurized. The ultrasonic waves are simultaneously impressed to the jig. The contaminated layer 5 is removed and a properly roughened surface is obtd. when the ultrasonic waves are impressed to the treating jig 9.

The surface of the electrode terminal is cleaned in this way and the adequate roughness is imparted to the surface of the electrode terminal. The stabilization of joining conditions, the yield of the operation, the joint strength and the reliability thereof are improved.

Abstract: PURPOSE:In the reaction between isobutylene and water and/or t-butanol and prussic acid, to obtain the titled compound in high yield, by specifying molar ratios of an acid as a catalyst and prussic acid to isobutylene and/or t-butanol. CONSTITUTION:In the preparation of N-t-butylformamide by reacting isobutylene and water and/or t-butanol with prussic acid in the presence of an acid catalyst (e.g., sulfuric acid), the reaction is carried out under conditions where a molar ratio of the acid to isobutylene and/or t-butanol is 0.05-0.8 and a molar ratio of prussic acid to isobutylene and/or t-butanol is 1.5-10, at 50-120 deg.C, preferably 60-90 deg.C.

IPC: G11B7/125
Filed: 1996-05-22
Abstract: PURPOSE: To control coherence of generated light without supplying high-frequency drive signals to a laser by providing a first bias means used for generating a light with a coherent length and a second bias means whose polarity is variable and reverse to the first. CONSTITUTION: A laser 2 has a p contact, which separates first, second and third semiconductor areas into a first contact 4, second contact 6 and third contact 8 for biasing respectively. The output power and coherent length of the laser 2 are functions of biases V1 and V2 which are given to the contacts 4 and 8 and the contact 6 respectively. The contacts 4 and 8 are always given a positive bias V1, and a reverse bias is applied to a second electrode 6. Thus, the coherence of a light can be controlled without supplying high-frequency drive signals to the laser.

Title: Cooling method of thyristor
Inventor: KOBAN MITSUYA
IPC: H01L23/467
Filed: 1983-07-13
Abstract: PURPOSE:To prevent the generation of accidents regarding a short circuit resulting due to the adhesion of trash, dust, etc. contained in cooling air by passing cooling air blasted by a blower in hollow hole in a radiator and cooling a thyristor. CONSTITUTION:An assembly in which thyristors S1-S6 are assembled among radiators F1 and F2, F3 and F4 and F5 and F6 with hollow holes by a pair of fixing fittings 6a, 6b is received in a case 1. Cooling air fed by a blower 13 is diffused in box body 11, passes through the hollow holes of the radiators F to cool the thyristors S, and is discharged from exhuast holes 14. Consequently, since cooling air does not collide directly with thyristor S themselves, trash, dust, etc. contained in cooling air do not adhere on contact section among the thyristors S and the radiators F or the outer surfaces of the thyristors S. Accordingly, there is no possibility of the generation of accidents regarding a short circuit resulting from these adhesion.
