Title: Linear led light source
Inventor: INOUE YUTAKA
IPC: B41J2/45
Filed: 1985-06-24
Abstract: PURPOSE:To make it possible to obtain illuminance higher than a fluorescent lamp by using a high-luminance type LED, by arranging the end surface of the P-N junction part of the LED chip toward the light emitting direction. CONSTITUTION:The quality itself of a high-luminance type LED chip 10 comprising GaAlAs and the like becomes closer to a transparent state in comparison with a low-luminance type LED chip. Therefore light beams can be emitted in many directions. A cylindrical lens 40 is arranged so as to be held between a supporting part 50, which is attached to a substrate 20 and has an L shaped cross section, and a flat supporting plate 51 in front of the LED chip 10. A P-N junction part 13 of the LED chip 10 and the cylindrical lens 40 are arranged on the same plane. The light rays, which are emitted from the P-N junction part 13 at the end surface of the LED chip 10, are utilized. The illuminance of the light, which is about three times that of the light emitted from an anode (or cathode) 12 on the upper surface of the LED chip, can be obtained.

Title: Pilot type steam trap
Inventor: WATANABE KENICHI
IPC: F16T1/22
Filed: 1993-05-14
Abstract: PURPOSE:To prevent outlet side water hammer caused when a pressure reactive valve is opened. CONSTITUTION:A pilot passage 12 is opened and closed through a lever 16 by floating and lowering a pilot float valve 14, and pressure of a pressure chamber 15 is controlled. Thereby, a pressure reactive valve composed of a piston 21 and a valve body 22 opens and closes a valve port 19, and discharges condensed water to an outlet 10. Before the pilot passage 12 is opened, a pilot flow valve 14 opens a bypass passage 13, and discharges the condensed water directly to the outlet 10. When the pressure reactive valve is opened, since the condensed water is discharged to the outlet through the bypass passage 12, even if the condensed water is discharged suddenly to the outlet side when the pressure reactive valve is opened, water hammer is not caused.

Filed: 1981-08-31
Abstract: PURPOSE:To have a fired linear speed with high accuracy and with a simple constitution, by giving the feedback control in accordance with a variance of the number of revolution of a motor that gives revolutions with a linear speed to a disk with a pickup, via a potentiometer, a divider circuit, etc. CONSTITUTION:The degree of shift of a pickup 3 is detected toward the radius direction of a disk 1 via a potentiometer 4. This detected voltage is processed by a divider circuit 5 and turned into the signal corresponding to the linear speed of the disk 1 with the pickup 3. Thus the number of revolution of a driving motor 2 is controlled for the disk 1 via an amplifier 6 and an adder 10. At the same time, the revolution of the motor 2 is detected by a frequency generator 7. Then the feedback control is carried out to a variance of revolution so that the motor 2 corresponds to the linear speed via adders 9 and 10 to obtain a coincidence between the output voltage of the circuit 5 and that of a frequency-voltage converting circuit 8 and obtained in accordance with the value detected by the generator 7. With this simple constitution, the linear speed of the disk 1 can be set constant with high accuracy, without affecting the potentiometer, the divider circuit, etc.
