IPC: A01G13/06
Filed: 1993-10-21
Abstract: PURPOSE:To take proper measures according to conditions of a field while suppressing the energy consumption in controlling freezing and frost injuries to crops. CONSTITUTION:This method for controlling freezing and frost injuries is to set a temperature around crops to be maintained for controlling the freezing and frost injuries at the set temperature (Tlo), sense the temperature (Tl) around the crops, start the combustion of a blower in the case of Tl<= Tlo, stop the combustion in the case of Tl>Tlo and repeat the procedures thereafter in blowing off warm air produced by a warm air producer around the crops and controlling the freezing and frost injuries. The warm air producer used in the method is provided by arranging a blower 16 just under a combustion chamber vessel body 32 for preparing a flame 40 and producing a combustion gas 42 and a blowoff port body 35 for mixing the combustion gas 42 with the open air 41 blown in by the blower 16 just above the combustion chamber vessel body 32. The upper part of the combustion chamber vessel body 32 and a combustion gas outlet 33 are protruded into the blowoff port body 35 and the combustion chamber vessel body 32 is surrounded by outer plates 39 of the apparatus made of a radiant heat reflecting material. Thereby, the loss in the produced thermal energy is suppressed to enhance the effectiveness of the warm air for controlling the freezing and frost injuries.

Title: Magnetic head
Inventor: HIGAMI FUMINORI
IPC: G11B5/235
Filed: 1987-11-12
Abstract: PURPOSE:To realize high-density recording by inserting a material having a specific magnetic permeability between -0.9 and 0.9 into a magnetic gap formed between magnetic pole surfaces facing each other. CONSTITUTION:The material 10 having the specific magnetic permeability between -0.9-0.9 is inserted into the magnetic gap 1 formed between the opposed magnetic poles of the upper magnetic pole 2 and the lower magnetic pole 3. Such material is the material contg. materials which are oxide consisting of a quaternary system of, for example, yttrium, barium, copper, and oxygen and exhibit superconductivity. The magnetic resistance of the magnetic flux is smaller nearer the surface of a medium 5 than the gap part at the time of writing and, therefore, the writing magnetic field is intensified if such head is used. Since the magnetic flux of a reading out signal does not cross the gap part, the signal output is improved. The use of the medium having large coercive force and high-density recording are thereby enabled.

Title: Semiconductor device
Inventor: TERAMOTO SATOSHI
IPC: H01L21/336
Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To practically reduce the distance between a channel formation region and a source/drain electrode and lower the resistance between them by forming a first layer, comprising metal and a second layer comprising titanium nitride next thereto and connecting the second layer to the gate insulation film as a gate electrode. SOLUTION: Since the resistance of silicide layer 111 of a thin-film transistor(TFT) is extremely small, the resistance between a channel formation region 104 and a metallic electrode 106 is practically decided by a distance displayed by (x). Since (x) is desirably at most 1 μm, resistance is substantially reduced. Therefore, the characteristics of a TFT are improved by reducing the distance between the channel region 104 and a source/drain electrode 106, thereby reducing the resistance between them. Furthermore, since resistance can be made small enough, the amount of impurities doped to the source/drain region 103 can be made small. In this way, characteristics are improved even if doping amount is small way.

Title: Flash-off time securing apparatus
Inventor: OSUMI KOICHI
IPC: B05C9/14
Filed: 1986-12-01
Abstract: PURPOSE:To shorten a line and to secure a flash-off time, by allowing a truck presence sensor and a passage confirming sensor to be connected with each other between a working position and an intermediate drying position and making a truck rotatable at the intermediate drying position. CONSTITUTION:An article 17 to be painted is stopped at every stop position by the truck stopping operation of a stopper 60. Work is applied to the article 17 to be painted when the stop position is a working position and, thereafter, a stopper operating switch 62 is operated to release the operation of the stopper 60 and a truck is moved to the next stop position. At this time, since the passage confirming sensor 81 of a front seat operates the stopper operating switch 62 after the sensing of the passage of the truck when the front seat is vacant, the truck moves to the next seat; however, when the previous truck is yet present, the stopper 60 receives the signal of a truck presence sensor 82 to be prevented from being canceled. Further, the article 17 to be painted rotates along with the truck at an intermediate drying position to shorten the interval between trucks.
