Title: Uniform material distributor
Inventor: TAKAHASHI MASAOKI
IPC: B65G65/32
Filed: 1988-02-22
Abstract: PURPOSE:To enable uniform distribution of material with respect to the axis of blast furnace by varying the inclination angle of a sizing board through utilization of the orientation of the material to be fed from a conveyor and sizing the material, while furthermore turning a hopper and distributing fine particles and masses in a spiral layer. CONSTITUTION:When material 6 is fed with a turning hopper 4 being operated, fine particles 7 and masses 8 accumulate respectively at the side A and B on the bottom of the hopper 4, and when the hopper 4 turns by 180 deg. the mass 8 is placed on the fine particles 7 which is placed on the masses 8. In other words, the fine particles 7 and the masses 8 are accumulated in spiral layer end distributed uniformly in the hopper 4. When a hinge 10 is fixed to the section C and the inclination angle alpha of the sizing board 9 is reduced as the material 6 accumulates, the material is placed in spiral layer with increasing radius and thereby the material 6 is accumulated in V-shape without colliding against the wall of the hopper 4 thus providing a high volume effect.

Title: Slip control device of torque converter
Inventor: SAWA KENJI
IPC: F16H45/02
Filed: 1988-02-22
Abstract: PURPOSE:To restrain a shock at the time of connecting and disconnecting a lock-up clutch by controlling the connecting force of the lock-up clutch through a slip condition where the connecting force is smaller at a low speed change stage as compared with a high speed change stage. CONSTITUTION:When transition of a lock-up clutch to the connecting condition or to the releasing condition is detected by transition time detecting means, connecting force control means control connecting force adjusting means in such a manner that the connecting force of the lock-up clutch gradually changes. According to a signal of speed change stage detecting means, change condition varying means vary the connecting force of the lock-up clutch through a slip condition where the connecting force is smaller at a lower speed change stage as compared with a high speed change stage. Thus, regardless of a speed change stage, a favorable changeover is conducted, so that a shock at the time of transition of the lock-up clutch between the connecting condition and the releasing condition can be restrained at all speed change stages.

Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To easily confirm the residual time of a sleep timer by counting and displaying a set sleep timer hour, and varying the brightness of a display in accordance with a count value of the timer hour. SOLUTION: A backlight is provided in a display section 3 consisting of a fluorescent display tube and a LCD, and in a dimmer control section 6, the brightness of a display of a backlight is switched by control of a microcomputer 1.

Title: Automatic ventilation device
Inventor: FUJIMOTO TAKUYA
IPC: F24F7/007
Filed: 1987-02-20
Abstract: PURPOSE:To inhibit a ventilation fan from operating when there is a person in the room by serially connecting to the power source a humidity sensor which senses the room humidity to control the operation of the ventilation fan and a human body sensor which senses the presence of a human to control the ventilation fan operation. CONSTITUTION:Under a condition that there is no person in a washroom A and the humidity level there becomes high due to steam from a bath room B or moisture on washing clothings, such is detected by a humidity sensor 10 and a ventilation fan 1 is operated. It stops when the humidity in the wash room A falls short of the reference value because of the ventilation. On the other hand, when there is a person in the washroom A, such is detected by a human body sensor 11 which causes a serial circuit with the humidity sensor 10 to be opened. Since the fan 1 is not operated when an operation switch 9 is open even if the humidity in the washroom A exceeds the reference value, the fan 1 is prohibited from operating regardless of the person's desire, and so, no uncomfortable cold draft due to air supply into the washroom A is felt.

Title: X-ray source
Inventor: OKADA IKUO
IPC: G21G4/04
Filed: 1982-03-10
Abstract: PURPOSE:To prevent the evaporated and scattered material of an electrode from adhering to the inner wall of a capillary hole of a polyethylene block and also to prevent the proof pressure of the polyethylene block from being deteriorated by making the bore diameter of the through hole of the electrode larger than that of the capillary hole of the polyethylene block. CONSTITUTION:When a discharge is started, the surface material of the inner wall of a through hole is evaporated and scattered by means of a discharge current, but the evaporated and scattered material does not adhere to the inner wall of a capillary hole 2 because the bore diameter of the through hole of an electrode is made larger than that of the capillary hole 2. Therefore, the proof pressure of a polyethylene block 1 is prevented from being deteriorated and a sufficiently high voltage is applied to both ends of the capillary hole 2, and a long life can be obtained as a powerful X-ray source.

IPC: C21D9/50
Filed: 1978-03-31
Abstract: PURPOSE: To reduce the residual stress at the welded joint without depending on the heat treatment, by welding at least the final layer of the deposited metal using an austenitic metal, and after that, by cooling to a temperature under the Ms point for causing the martensitic transformation.  
     CONSTITUTION: At least the final layer of the deposited metal of the welded joint is welded with an austenitic metal, and is cooled to a temperature under the starting point of the martensitic transformation (Ms point) for the purpose of causing the martensitic transformation in the welded final layer; hereby, the shrinkage of the deposited metal is canceled by the expansion due to the transformation from the austenite into the martensite.
