IPC: H05B44/00
Filed: 1992-03-06
Abstract: PURPOSE:To avoid noise production reversing the phase of acoustic pressure generated by elements to eliminate interference, by constituting an EL display unit so that two EL elements are over-lapped so as to be laminated over a glass substrate, and thereby applying rectangular wave AC current with its phase reversed to each space between the electrodes of each element. CONSTITUTION:An EL display unit 1 is made up of a glass substrate 3, and of following parts which are provided over the glass substrate, they are a first transparent electrode 5, a first insulating layer 7, a first EL luminous layer 9, a second insulating layer 11, a second transparent electrode 13, a third insulating layer 15, a second EL luminous layer 17, a fourth insulating layer 19 and a back face electrode 21. In this case, ITO and the like are used for the electrodes 5, 13 and 21, Mn, TbOF and Zn for a luminescent center, are used for the luminous layers 9 and 17, and alumina and the like are used for the insulating layers 7, 11 and 15 and 19 respectively. The EL display unit is constituted as mentioned above, and when the layers 9 and 17 are made luminous with voltage applied to the electrodes 5 and 21, rectangular wave AC current to be applied is turned over in phase between the electrodes, and acoustic pressure produced by the layers 9 and 17 is concurrently turned over between the layers. In this case, these are synthesized, and let acoustic pressure interfere therewith between the layers, so that noise production is thereby eliminated.

Title: Self-traveling painting apparatus
Inventor: NISHIMURA FUMIO
IPC: B05B13/02
Filed: 1984-03-15
Abstract: PURPOSE:To eliminate the loss of time when the material to be painted is conveyed by traveling two carriages, allowing one carriage to be on standby when the other carriage is subjected to painting, and allowing the other carriage to proceed automatically to the painting position when the painting is completed. CONSTITUTION:Two carriages 3 and 4 carrying a masked material to be painted are respectively allowed to travel automatically on a loop track. And when one preceding carriage is situated at the position B where the material is painted by a painting robot, the other carriage 4 approaches the standby station C1. The succeeding carriage 4 proceeds automatically to the painting position for replacing the carriage 3, when the painting of the carriage 3 is completed. The loss of time when the material to be painted is conveyed is practically eliminated in this way, and the automatic conveying efficiency can be remarkably increased.

Title: Injection feeder
Inventor: INAGAKI TAKEO
IPC: B65G53/42
Filed: 1980-04-18
Abstract: PURPOSE: To prevent reverse flow of air in a feeder by opening a choking tapered section constituting a high pressure section formed at a charging port side of an air discharge pasage in a feeder body adjusting itself to the flow of air injected fast from a nozzle section of an inner cylinder.  
     CONSTITUTION: Air containing a solid matter is discharged fast from a nozzle section 14 of an inner cylinder 15 in the second stage feeder body 9, sucked into the body 9 through a charging port 10 with an aid of a tapered choke section 16 and fed under pressure through a discharge passage 12. Increased pressure due to a pipig resistance at the nzzle section 14 tends to reverse a part of the air flow to a low pressure section of the feeder body 9 in the preceding stage. But, there is a high pressure near the choking tapered section 16 of the preceding stage feeder body 9 due to a fast air injected from the nozzle section facing it and suction of air about the tapered section 16 thereby checking the reverse flow from any subsequent stage feeder.

Abstract: PURPOSE:To make the control of steel pipe temp. with the higher accuracy possible by measuring the roughness on the surface of a steel pipe to be treated prior to the insertion thereof into a furnace, determining the total area per unit area of the steel pipe and controlling the furnace temp. of each furnace block. CONSTITUTION:The steel pipe 11 is inserted into a continuous treatment furnace 1 and is conveyed successively by rollers 10 in a preheating furnace 2, heating furnaces 3-7 and holding furnaces 8, 9, by which the steel pipe is subjected to a heat treatment. The treated pipe is ejected from a furnace outlet 12. The roughness on the surface of the steel pipe 11 is measured by a roughness measuring instrument 15 prior to the insertion of the steel pipe 11 into the furnace 1 and is outputted to a relational comparator 16. The total area per unit area of the steel pipe 11 is calculated from the measured value in the relational comparator 16 and is reflected to the heat treatment control cycle determined by taking the size, material quality, etc., of the steel pipe 11 into consideration, by which the furnace temp. or conveying speed of each block of the furnace 1 is controlled.

Title: Bumper guard with alarm whistle
Inventor: KANESHIRO TOSHIO
IPC: B60R19/48
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent or reduce damage caused by contact of an automobile bumper with an obstacle. SOLUTION: A bumper guard 2 with alarm whistle having a simple construction and manufacturable at a low cost is configured by a first damper member 3 and a whistle (pipe whistle) 4 (without the use of electrical means). The first damper member 3 is molded from synthetic rubber or the like into a hollow shape with elasticity, such that it is provided with a curved surface in a longitudinal direction as well as a hollow portion 10 on the inside. The whistle 4 generates an alarm sound by blowing of air. The bumper guard may also take a multi-layer construction wherein a second damper member made of molded elastic tube or sponge-filled form is stored and retained inside the hollow portion 10 of the first bumper member 3. Accordingly, by attaching the bumper guard on a corner of a bumper 1, in the case where that portion comes into contact with an obstacle, compressed air inside the hollow portion 10 of the first damper member 3 generates alarm sound. This alarms a driver to activate the brakes quickly or to take operative measures at an early stage, so as to prevent damage caused by contact with an obstacle or to reduce such damage.
