Abstract: PURPOSE:To make the gas coming from a pannel being dissolved during heat treatment to be burnt by feeding air by a method wherein wavelike unevenness is formed on the surface of a frit layer on the funnel seal surface in order to form through holes when the pannel is placed thereon. CONSTITUTION:A frit layer 3 is formed by coating the seal surface 2 of a funnel 1 applied with graphite with the paste, wherein a rehicle consisting of an organic binder and an organic solvent is kneaded with frit powder, while wavelike unevenness with a pitch of 5-10mm. is formed by pressing a metallic mold or the like at every interval of the material in an intermediate dry state proceeding on the frit layer. Next, a panel 4 and the funnel 1 incorporated in a frame are transferred into a mesh belt type sealing furnece to be raised in temperature up to about 380 deg.C at the temperature rising rate of about 10 deg.C. Thereby the quantity of oxygen contained in the air inside of a tube is short by about 20% as compared with the quantity of oxygen required to burn completely organic substances of the panel. However, the lacking oxygen can be supplied by throughholes 5 which are formed by wavelike unevenness provided on the frit layer and piercing in-and-outside of the tube.

IPC: E05B65/02
Filed: 1990-03-15
Abstract: PURPOSE:To prevent doors from being accidentally opened by locking the door only when a parcel sensor is sensing the presence of the parcel and prevent children or the like from being confined in the box by employing a safety sensor for sensing the entrance of animals or the like. CONSTITUTION:Doors 4A, 4B are locked by the pressing on a locking button P1 when a parcel sensor S1 is sensing the presence of a parcel. As a door sensor S2, various switches may be used for detecting the contact of the doors 4A, 4B as well as a proximity switch for detecting the proximity of the doors. A safety sensor S3 may be of any type as long as it detects unauthorized entry of a moving body such as an animal or a child and various sensors such as infrared sensors may be used for it. Because the safety sensor S3 detects the entry of a child or an animal, the output of the sensor prevents the child from being confined to improve the safety. The disadvantage of confining animals is also eliminated.

In this case, the inner pressure of an oil chamber 6 that is communicated to the inside of the hydraulic pump 3 through each oil guiding hole, is elevated, and a piston member 5 is pressed to a holding plate 23 of a planetary gear 22 thereby. A gear plate 24a on which a second ring gear 24 is formed, and a rear flange 20a on which the holding plate 23 as well as a ring gear 20 are formed, are pressed with each other through frictional plates 26, 25, respectively. The planetary gear 22 is locked thereby, and an input shaft 1a and an output shaft 1b are directly connected with each other. The relative rotation between a rotor 30 and a cam ring 31 is suppressed thereby.
