Title: Fluorescent lamp
Inventor: ITO HIDENORI
IPC: H01J61/067
Filed: 1989-08-24
Abstract: PURPOSE:To prevent a bulb wall near an electrode from getting an abnormal temp. in the event for ex. of half-wave discharging by installing a heat shutting member between the electrode and the end wall of the bulb. CONSTITUTION:When a fluorescent lamp 20 approaches its latest period of lifetime, emitter fitted with electrodes 26, 26 sputters. When the emitter fitted to one electrode 26 sputters perfectly, a half-wave discharge condition is attained, and an electrode filament with emitter sputtered is burnt off, and the heat at this time may generate cracks in the stem 27. Because a heat shutting plate 30 consisting of heat resistant metal such as stainless steel is installed between the electrode 26 and stem 27 in such an arrangement that this plate 30 covers the rear of the electrode 26, the heat of the electrode 26 is prevented from radiating to the stem 27. This prevents initiation of cracks in the stem 27.

Title: Air feeding and discharging device
Inventor: KIKUTANI FUMITAKA
IPC: F23L17/04
Filed: 1990-08-15
Abstract: PURPOSE:To perform always normal air feeding and discharging operation without occurrence of any immersion of rain water or mud even if an air feeding and discharging device is installed at an under-ground place, for example, by a method wherein an air feeding port is disposed at a central part of a parasole-shaped upper cover, a guiding member covering a communication port within an air feeding passage and constituting a rain passage is installed in a spacing with the air feeding cylinder, a distance between the air feeding port and the air discharging port is spaced apart and further a flowing direction of each of the feeding air and discharging air is separated from each other. CONSTITUTION:As a fan 9 of a main body 10 is operated, the atmospheric air is sucked from an air suction port 28, passes through an air feeding passage 22 within an air feeding cylinder 23 and then is guided into a case 28 mounted at an underground place. Discharged gas completed its heat exchanging operation is collected at an air discharging hood 15, passes through an aid discharging passage 20 within an air discharging cylinder 21 and then is discharged from a blowing passage 25 into the surrounding air. Due to this fact, a distance between the air feeding part and the air discharging part is increased and a refeeding of the discharged air does not occur. For example, when it is started to rain, the parasole-shaped upper cover 24 any act as an umbrella for the air suction port 28. Since a gallery 27 is disposed, entering of rain water from the air supplying port 28 is substantially reduced. Even if rain water avoids the gallery 27 during storm and enters at the air suction port 28, the rain water is fed into a rain passage 31 by the guiding member 30 and discharged out of the air feeding cylinder 23 through a communication port 29.

Title: Energy minimum conservation type face heating method, face heater and power controller
Inventor: KIN RYUSHUTSU
IPC: F24D13/02
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent runaway of temperature by starting application of power to a face heater, and then abruptly dropping the applied power to the heater to an arbitrary value after lapse of preset time in a method for face heating by applying power to the heater and then raising temperature of the heater to heat. SOLUTION: A heater 2 is formed by coating a base material having electrodes 3 with conductive paint, and coating the overall material with an insulating film. When a voltage is applied to the electrodes 3 via lead wires 6, a current flows between the electrodes 3. And, Joule heat is generated so that temperature of the heater 2 is raised to conduct heating. In the face heater using the heater 2, after the temperature of the heater 2 arrives at a sealing point, a resistance value is abruptly raised so that the current scarcely flows. Hence, since the temperature of the heater 2 is not raised any more, the power applied to the heater 2 is abruptly dropped to an arbitrary value after lapse of the preset time by a timer. Thus, dissipation power can be suppressed to the lowest possible limit.

Title: Water leak detecting device
Inventor: OKABE MASAYOSHI
IPC: G01F1/00
Filed: 1990-08-18
Abstract: PURPOSE:To eliminate damage caused by a water leak by providing a water- absorptive expanding body, an expansion detecting means, and a means which warns the water leak according to detection information. CONSTITUTION:When there is no water leak, an electrode plate 10 and an electrode 11 on the top surface of a case 9 are separated from each other and a buzzer 13 does not sound. If water leaks, the water-absorptive expanding body 9 absorbs the water through a water-permeable case 9. The water- absorptive expanding body 8 absorbs the leaking water up to its limit of the absorption amount of water to prevent the inside from being filled with water and also expands in volume greatly to press up the electrode plate 10 through the case 9, thereby bringing it into contact with the electrode 11. The buzzer 13, therefore, sounds to indicate the water leak occurrence, thereby preventing the damage due to the water leak. In another way, a reed switch 23 is arranged in a space in the center of a magnet 22 where magnetic flux is large and the water-absorptive expanding body 8 absorbs water and expands in volume to move up the magnet 22; and the magnetic flux in the space at the periphery of the reed switch 23 is reduced and the switch 223 is broken to generate an alarm.

IPC: B60T7/12
Filed: 1994-09-12
Abstract: PURPOSE: To avoid the wasteful operation of a brake as much as possible in the case of a brake device which can reduce the action delay of the brake. CONSTITUTION: A movement speed at the time of an operator foot 136 accelerator pedal 134 being released is detected on the basis of output value change quantity per unit time of a throttle opening sensor 124. In the case of the movement speed being more than a set value, it is surmised that the degree of emergency is high, and a brake is operated. An opening/closing valve 66 is changed over to a communicating state only during a communicating time, and a brake fluid is fed to a wheel cylinder 14. A pad is made to come into slide contact with a disc rotor, and initial braking force is generated. In the case of the movement speed being more than the set value, the accelerator pedal 134 is released and then a brake pedal 10 is stepped on in most cases, so there is little chance of brake operation becoming wasted.
