IPC: F24F7/06
Filed: 1986-01-16
Abstract: PURPOSE:To provide a ventilation device having a stable ventilating function by a method wherein a second blower composed of a transverse flow fan is arranged in front of a first blower attached in a fixing hole which faces toward an indoor side. CONSTITUTION:This device is composed of a first blower 3 fixed with its suction port 2 being directed toward an indoor side in respect to a fixing hole and a second blower 5 supported by two parallel supporting arms 4.

Title: Mass spectrometer
Inventor: TAKADA YASUAKI
IPC: G01N27/62
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To stabilize analysis for a long time even if a migration compatible solvent containing non-volatile salt is used by having a vibrator for causing vibration to a needle electrode. SOLUTION: A needle electrode 22 is arranged in the vicinity of a first pore 8. A positive high voltage is applied in positive ion measurement and a negative high voltage of several kilovolt for instance is applied in negative ion measurement from power supply 53 of a high voltage. Thereby, a corona discharge is generated, and primary ions for chemical ionizing is generated. It is desirable that a needle electrode 22 is arranged in a needle electrode cover 26 to retard deposition of salt to the needle electrode 22. A supersonic wave vibrator 28 is attached on the needle electrode 22 or a needle electrode stand 25. When measurement is executed continuously for several hours, non-volatile salt is deposited in the vicinity of a front edge of the needle electrode 22.  Then, vibration is applied to the needle electrode 22 with the supersonic wave vibrator 28 to peel sludge, which drops to remove. Since non-volatile salt is deposited on the needle electrode 22 is very fragile, it is possible to remove the salt by dynamics action such as vibration and the impact, etc., to cause acceleration in the needle electrode 22.

Title: Refuse compressing machine
Inventor: YAGI YASUO
IPC: B30B9/32
Filed: 1982-01-20
Abstract: PURPOSE:To compress refuse thoroughly without wasting electric power consumption and time by setting compressing time as desired in conformity with the restoring force occuring in the mass and amt. of the refuse. CONSTITUTION:When a compressing plate starts descending, a stop switch 15 is turned on. A capacitor C3 discharges electricity gradually in the circuit of a stepless adjusting knob switch 13 constituting a part of a timer circuit and according to the discharge thereof, the G potential with respect to the A potential of a PUT drops and at the point of the time when said potential drops slightly lower than the A potential, the A and G of the PUT are forward biased and the PUT is turnd on. In other words, when the quantity of the discharge is large, the time between the same is short and when said quantity is small, the time is conversely long. With this constitution wherein the quantity of discharge is adjusted by setting the magnitude of the resistance as desired, the switch 13 sets the compression time as desired. When the compressing plate arrives at the max. height, the switch 15 is turned off, and a motor 8 is stopped.

Title: Seal device of nuclear reactor well
Inventor: MIYASAKA MASANORI
IPC: G21C13/00
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the amount of the heat transferred from a reactor pressure vessel, ease the concentration of thermal stress and load and improve the strength of the vessel by placing a basin seal in a flange part of the reactor pressure vessel. SOLUTION: Heat in a reactor pressure vessel 1 is transferred from a flange part 11 to a basin seal 12, when heat conduction is suppressed because of a space X formed between the flange part 11 and the seal 12. Moreover, the vertical layout of the space X at equal intervals ensures a uniform heat transfer in the direction of the radius to reduce the occurrence of thermal stress on the seal 12 and an installation position for it.  In case of the displacement of the pressure vessel 1 due to thermal expansion and contraction and the application of external force to it, impact is made on the flange part 11, the seal 12, a support plate 13 and an intermediate connection 14 which is less strong mechanically than the pressure vessel 1, but the setting of the thickness of each taper part as well as the installation of taper parts 12a, 12b and 13b in the connecting points of them makes it possible to ease the concentration of stress.

Title: Optimum communication speed automatic setting system for modem
Inventor: TANAKA KAZUYUKI
IPC: H04L29/06
Filed: 1992-01-21
Abstract: PURPOSE:To attain communication with a high efficiency at all times by automatically optimizing the communication speed of a MODEM. CONSTITUTION:After the connection to a called side MODEM with the electric physical specifications at an optimum communication speed, a caller MODEM confirms whether or not an optimum communication speed setting function is in existence in the called party (signal 27). When the function is in existence, the called party sends a reply data frame to the caller side (signal 28). The caller side sends check data used to check line quality for a predetermined number of times, 10 times in this case to the called party (signal 29). The line quality is checked from the sent check data and the called party avoids the setting of ranking of the communication speed when the current communication speed is not proper to report the reply result of the line quality check to the caller side in a data frame (signal 30). The caller side sets the ranking at the informed communication speed. The processing causing the signals 29-30 is repeated till the communication speed adaptive to the line quality is obtained.

Title: Bias magnetic field applying method for magneto-optical recording and reproducing device
Inventor: MAKITA AKIHIKO
IPC: G11B11/10
Filed: 1989-01-17
Abstract: PURPOSE:To avert the deterioration of recording data by turning a permanent magnet for impressing bias magnetic fields to a magnetic medium to a prescribed position according to modes,fixing the same to this position and selecting the direction where the magnetic fields are to be impressed. CONSTITUTION:The permanent magnet 26 for applying the bias magnetic fields 41, 42 on the recording medium 20 is turned and positioned according to the modes. The magnetic field 41 is applied in one direction perpendicular to the medium 20 at the time of recording. The magnetic field 42 is applied in the direction reverse therefrom at the time of erasing. The direction of the applied magnetic field 50 is determined in the direction orthogonal with the direction 51 of magnetization of the magnetic layer 22 of the medium 20 in the mode exclusive of recording and erasing. The magnetic field acting on the magnetic layer at the time of the mode exclusive of recording and erasing does not have the component in the direction where the magnetization direction of the magnetic layer is inverted according to this constitution. The inversion of the magnetization direction does not, therefore, arise even if a laser beam is strong at the time of reproducing or disturbance acts at the time of erasing. The deterioration of the recording data is thus prevented.
