IPC: H01G13/00
Filed: 1994-09-02
Abstract: PURPOSE: To make it possible to uniformly coat an electronic part by a method wherein a barrier, with which a backward flow of powder coating resin is prevented, is provided on the terminal of movement of a leveller in a circulation bath. CONSTITUTION: A barrier 10, with which the backward flow of powder-coating resin 1 is prevented, is provided on the terminal of movement of the level adjusting plate 3A in a circulation bath 2. The above-mentioned barrier 10 is formed in the length extending on the whole width of the circulation bath 2, and a very small gap (δ) is formed between the lower edge of the barrier 10 and the bottom face of the circulation bath 2. Also, the upper edge of the barrier 10 is adjusted in such a manner that it becomes almost the same height as the upper surface of the accumulated layer of the powder coating resin 1. Also, a plurality of aperture parts are dispersively provided on the lower part of the barrier 10. The opening ratio of the above-mentioned aperture part is set at 50 to 60% of the area of the lower part.  As a result, a painting operation can be performed uniformly on the painting region of the electronic part by dipping it in the same depth in whatever place of the accumulated layer, which is adjusted by a leveller, of the powder coating resin in the circulation bath.

IPC: H01L23/15
Filed: 1987-09-18
Abstract: PURPOSE:To obtain the titled bonding material having an almost same coefft. of thermal expansion as AlN sintered body, and forming a bonded layer having satisfactory wettability and contg. no foams, by specifying ranges of the compsn. of SiO2, B2O3, Al2O3, and CaO constituting the bonding material. CONSTITUTION:The title bonding material consists of 40-60wt.% SiO2, 20-30wt.% B2O3, 9-20wt.% Al2O3, and 3-15wt.% CaO. Less than 3wt.% ZrO2 may be further added to the bonding material. ZrO2 is effective for improving chemical durability of the vitrified bonding material. When the amt. of added ZrO2 exceeds 3wt.%, uniform melting of the vitrified bonding material is difficult, so the coefft. of thermal expansion of obtd. product becomes high. In order to bond a sintered aluminum nitride with the bonding material, raw materials for bonding material are mixed and melted in the first stage, then vitrified by cooling, and obtd. vitrified product is crushed to powder having <=0.5mu means particle diameter. By regulating the particle size to the above described range, a uniform bonded layer can be formed.

Abstract: PURPOSE:To facilitate sighting by vision and to enable the highly precise sighting by sampling a visual field by a polar coordinate system, obtaining a camera picture and detecting an object position inside the picture. CONSTITUTION:A concentric circular scanning type television camera 11 generates the picture for which the visual field is sampled by the polar coordinate system Also, a picture processing circuit 12 segments an object area inside the picture of the television camera by using the information of the brightness, color and movement, etc., of an object based on the picture from the concentric circular scanning type television camera 11 and calculates the centroid of the object area inside the picture. By using the calculated result, the object position is obtained. Also, a motor-driven pan head 13 rotates the visual line of the television camera in a direction corresponding to the object position based on an object position analyzed result in the picture processing circuit 12. Thus, the picture of the rotationally/axially symmetrical object becomes a vertically developed regular graphic and the sighting by the vision is facilitated. Also, since the picture is smaller in a center in the polar coordinate system and the information can be obtained in detail, the highly precise sighting in the center of the visual line is enabled.

Title: Short distance driving method for pulse motor
Inventor: MAKINO MITSUNOBU
IPC: H02P8/00
Filed: 1991-09-17
Abstract: PURPOSE:To realize a speed pattern for driving a pulse motor different from a conventional one where the pulse motor is driven in the order of start - acceleration - constant speed (high speed) --deceleration - constant speed (low speed) - stop because this speed pattern can not be applied on a head moving motor in a disc medium tester where the moving amount is very small and the number of pulses is very low. CONSTITUTION:A pulse motor is started at a starting time point t1 with high speed 3500pps and that speed is sustained. Deceleration is started at time point t2 when the number of remaining pulses is lower than 12 and when the speed reaches a final speed of 1200pps at time point t3, that speed is sustained and the pulse motor is stopped at time point t4 when the motor arrives at a target position. Consequently, short time movement can be realized by eliminating the accelerating region and low vibration stoppage can be realized by performing deceleration only at the time of stoppage.
