Title: Rotary regenerative heat exchanger
Inventor: KATO TAIZO
IPC: F28D19/04
Filed: 1986-05-02
Abstract: PURPOSE:To prevent contamination of clean gas due to dust and to keep a fluctuation in a differential pressure, produced between two gases, at a specified value or less, by a method wherein, when gas containing dust is introduced to a heat transfer element, dust is collected by means of a filter to prevent adhesion of dust to a heat transfer element body. CONSTITUTION:A part of a filter 28 faces a hood 15, and low temperature gas containing dust is introduced from the hood 15 in a state that another part faces a hood 18, and high temperature clean gas is introduced from the hood 18. During passage of the gas containing dust, introduced from the hood 15, through the filter 28, dust is collected to produce clean gas. After the clean gas passes a heat transfer element 26 and is heated, it is brought into contact with a catalyst layer 27 to change a noxious component into a harmless component, and is increased in temperature to cause it to flow from a hood 16. This constitution prevents dust from adhesion to the heat transfer element body 26 and the catalyst layer 27, resulting in prevention of the occurrence of a state in which the heat transfer element body 26 and the catalyst layer 27 are closed and a pressure loss is increased due to dust.

Title: Communication control system
Inventor: AONO KENJI
IPC: H04L12/40
Filed: 1990-04-16
Abstract: PURPOSE:To enhance the communication efficiency of the entire network by controlling a communication control parameter from collected communication information on a transmission medium dynamically in details. CONSTITUTION:A communication state on a transmission medium 3 is always monitored by a monitor block 10 and the data is stored in a register block 11. A command block 12 generates command information to increase the communication efficiency of a network for a general station 2 and sends the information to the station based on the data stored in the block 11. Upon the receipt of the command information from a management station 1 by a reception block 20 of the general station 2, a revision block 21 revises a communication control parameter based on the command information. For example, when number of times of failed transmission to a specific station is very much, whether the cause resides in a transmission medium or in the station itself is discriminated from the operating state of the entire network. When it is discriminated that there is a problem in the On the other hand, of the station, the processing such as a request of the transmission of the current operating state or the revision of the communication control parameter of a relevant station is attained.

Title: Magneto-optical reproducing device
Inventor: FUJIWARA YASUHIRO
IPC: G11B11/105
Filed: 1990-04-17
Abstract: PURPOSE:To stably reproduce both recording media as mentioned below in simple constitution by keeping the polarization state of light to be incident upon a recording medium unchanged when the recording medium is a magneto-optical recording medium and changing the polarization state of light to be incident upon a recording medium when the recording medium is some recording medium other than a magneto-optical system. CONSTITUTION:Light emitted from a light source (semiconductor laser) 11 is led to a recording medium 16, and its return light is separated from an optical path proceeding the recording medium 16 from the light source 11 by an optical path separating means (beam splitter) 13, and is detected by photodetectors 19a and 19b. Then, when the recording medium 16 is the magneto-optical recording medium, the light emitted from the light source 11 is incident upon the recording medium 16 without changing the polarization state of this light by a polarization state varying means 14. On the other hand, when the recording medium 16 is the recording medium other than the magneto-optical system, the light emitted from the light source 11 is incident upon the recording medium after changing the polarization state of the light by the polarization state varying means 14. By this method, both magneto-optical recording medium and recording medium another than the magneto-optical system are stably reproduced in simple constitution.

Title: Discharge lamp
Inventor: INOUE AKIHIRO
IPC: H01J61/56
Filed: 1978-08-21
Abstract: PURPOSE: To restrict a starting high voltage pulse of a discharge lamp lower than dielectric breakdown voltage and facilitate readily starting of the lamp by connecting a voltage absorbing element for absorbing high voltage pulse higher than predetermined level as compared with necessary starting voltage electrically in parallel with a light emitting tube.  
     CONSTITUTION: A negative resistance element 15 is arranged as voltage absorbing element within the outer tube 11 of a discharge lamp started by high voltage pulse, and connected electrically in parallel with both electrodes. The element 15 has 4,000 volts of maximum voltage value, and 500 volts of maintenance voltage. If high voltage pulse generated upon opening of a bimetal 6 due to energization of a filament 7 exceeds 4,000 volts, it is absorbed by the element 15. Thus, the voltage level of the starting pulse is restricted to less than the voltage breakdown value at the respective components to increase the pulse generating number in the probability corresponding to the area of the portion surrounded by characteristic curves a1Wa3 shown to thereby facilitate readily starting of the lamp.

Abstract: PURPOSE:To improve reliability of a measured value, by forming an apparatus of a highly heat-conductive insulator, and forming a recess part in which a body to be measured is housed at one side of the apparatus. CONSTITUTION:When the surface resistance of a body to be measured is measured, at first, said body to be measured is housed in a recess part 12 of a base stage 14. The recess part 12 of the base stage 14 is coupled with a protruding part 18 which is formed on a mounting stage 16. A temperature measuring sensor is further attached. Under the state wherein the base stage 14 and the mounting stage 16 are assembled, the base stage 14 and the mounting stage 16 are assembled into a temperature control apparatus. Thus, the temperature of the body to be measured can be made uniform. Since the temperature of the body to be measured, the mounting stage 16 and the base stage 14 is uniform, the sensor which is attached to the base stage 14 indicates the temperature of the body to be measured without directly measuring the body to be measured. In this way, the body to be measured can be measured at the uniform temperature all the time, and the reliability of the measured value is improved.
