Title: Flat platelike linear pulse motor
Inventor: HINO SATOSHI
IPC: H02K41/03
Filed: 1989-12-07
Abstract: PURPOSE:To reduce an eddy current loss and to improve driving efficiency by laminating a plurality of thin plates to form a yoke in which a coil is wound, and securing an armature in which pole teeth are formed on the upper surface of the yoke. CONSTITUTION:A stator 2 is formed of a yoke 11, a coil 12, an armature 13 and a permanent magnet 16. The yoke 11 is formed by laminating a plurality of thin plates molded in the same shape, and the magnet 16 is held by the two yokes 11 therebetween. An armature 13 in which pole teeth 33 are formed previously by cutting at four positions opposed to the poles of the yokes 11 on the upper surface of the flat plate is placed on the yoke 11 and secured. Thus, an eddy current loss when the coil is driven is reduced to improve its driving efficiency. Since the teeth are formed on the armature of separate member from the yoke, machining accuracy is improved, and its yield is improved by forming the teeth corresponding to the plurality of armatures on the single material.

Abstract: PURPOSE:To suppress electromagnetic wave leaking from a display device without impairing its resolution and image quality by providing an impedance matching resistance and a filter circuit for cutting off high frequency band without grounding portion, at the picture signal input stage of a picture amplifier. CONSTITUTION:A display device is provided with a filter 6 for cutting high frequency band, which is provided at the picture signal input stage of a picture amplifier 5 and in which an grounding portion is not included, and an impedance matching circuit 4 provided at the front stage of the filter 6. The filter 6 for cutting off high frequency band is, for example, an LC parallel resonance type filter and not provided with the grounding portion. Accordingly, since the impedance on a signal source side becomes infinite near a resonance point, impedance matching is not disturbed by the circuit for impedance matching 4 provided on the front stage. Thus only unnecessary high frequency band component of image signal from the signal source is damped without any disturbance to suppress reflection of electromagnetic wave from the image amplifier 5 without reducing its resolution and image quality of the display device.

Title: Fire resistant ceiling member
Inventor: KOJIMA ISAO
IPC: E04B1/94
Filed: 1994-12-22
Abstract: PURPOSE: To enhance the degree of design and enhance the fire resistance by letting a coating layer be formed over the surface of a rigid substrate, which produces a foamed fire resistant layer when heated. CONSTITUTION: A primer processing layer 21 is interposed in a boundary surface between a coating layer 20 applied on the surface of a rigid substrate 30 and the rigid substrate 30 so as to allow joined strength to be increased, and furthermore, a finishing layer 60 is given thereto as a topcoat. In this case, as coating material, the mixture of the binding material of carbide forming material with foaming agent is used, and fire resistant foamed carbide is to be produced when the aforesaid mixture is heated. Therefore, fire resistant carbide is formed in a coating layer 40 because of flame and heat in case of a fire, and foaming material is then foamed, so that a fire resistant layer 10 as thick as required is thereby formed.  Since a foamed fire resistant layer 10 increases its thickness by itself, its heat insulating effect is enhanced, heat transfer to a ceiling plenum section at the back face side is blocked, and heat transfer to the rigid substrate 30 is thereby prevented.
