Title: Multi-layer amorphous alloy thin band for iron core
Inventor: SATO SHUN
IPC: H01F1/14
Filed: 1988-06-20
Abstract: PURPOSE:To provide an amorphous alloy thin band for an iron core which has a highly saturated flux density and a high thermal stability by using for an outer layer a high amorphous alloy having a higher crystallization temperature than an inner layer. CONSTITUTION:An amorphous alloy having a high operating temperature BS is placed inside B while an amorphous alloy having a high thermal stability is plated outside A1 and A2. The inner alloy is an amorphous alloy such as B14 (atomic %) having a high BS so as to meet a formula BS>=1.63T. For the other layers, an alloy such as Fe79W3Si6B12 having a high thermal stability with 520 deg.C or more of TX and 1.0T of BS is used. Why 1.63T or more of BS is required for the alloy is to raise the average BS of a multi-layer substance and why 520 deg.C or more of crystallization starting temperature TX when heat is started to be generated is required when a temperature up speed of the outer alloy is 10 deg.C/min is to crystallize the inner alloy at as high temperature as possible. When this multi-layer amorphous alloy thin band is used for a power transformer, it is desirable that the thickness of the outer layers is made as thin as possible.

Title: Trigger signal generator
Inventor: FUJIWARA KATSUMI
IPC: G01B11/02
Filed: 1982-08-30
Abstract: PURPOSE:To decrease the influence that disturbance gives on a trigger signal even if there is the disturbance and to improve the accuracy in measurement, by focusing a scanning beam at the point above a sample to be measured, providing a pinhole at that point and detecting the scanning beam with a photodetector. CONSTITUTION:When a scanning beam 10 is directed to a scanning reference position, the beam is reflected by a mirror 11 and is detected through a pinhole 12 with a photodetector 13 for trigger. Therefore a signal of a sharp rise (fall) as shown by (5-1) can be obtd. for the output signal from the detector 13. Even if a disturbance in the quantity of light, temp., etc. arises and a fluctuation appears in the signal, the binary encoded signal from a processing circuit fluctuates less (5-2). Therefore, if the part to be measured of a sample 4 to be measured, for example, the sample 4, is a photomask for a printed board or the like, the accuracy in measuring the pattern width thereof is improved.

Filed: 1980-10-29
Abstract: PURPOSE:To facilitate piping and to reduce the storage space of an antenna, by constituting the balanced-to-unbalanced transforming circuit of the antenna of a two-stage stack array by the external conductor of a coaxial feeding tube. CONSTITUTION:The transmission power from a feeding terminal 1 is fed to a coaxial feeding tube 3 through a coaxial feeding tube 8.

Feeding points 91 and 92 are connected to dipole antennas 10 and 41 for vertical polarization respectively. The conductor pole for a balanced-to-unbalanced transforming circuit for the antenna 41 is constituted with a conductor pole 31, and the conductor pole of a balanced-to-unbalanced transforming circuit for the antenna 10 is the external conductor of the coaxial feeding tube 8. Thus, one pipe is omitted, and therefore, many antennas are arranged on the surface of a pole 7 of a limited thicness.

Abstract: PURPOSE:To prevent dew condensation from being caused at an easy-to- condensate place such as a window, etc., in a room. CONSTITUTION:An up-down rotation signal and a left-right rotation signal generated by a remote control input device are inputted to a dew condensation controller 30 in advance so as to direct the uptown and left-right angles of the louver of an air conditioner to the window, and the movement position of the louver 12 is determined by a louver up-down driving motor 13 and a left-right driving motor 14 and stored in an air conditioner controller 20. The amount H of vapor nearby the window which is obtained by a temperature sensor 41 and a humidity sensor 42 is compared with the amount HO of saturated vapor; when the difference between the both is smaller than a certain quantity DELTAH and dew condensation is easily caused, the louver 12 is moved to the stored position and an air conditioning part 10 is placed in dehumidifying operation. Consequently, dry air flows to the window to prevent dew condensation on the window. When the difference is larger than the certain quantity DELTAH and no dew condensation is caused, the louver 12 is put back to its original position and the air conditioning part 10 is placed in normal operation. Consequently, the dry air is prevented from excessively being supplied into the room.
