Filed: 1990-04-26
Abstract: PURPOSE:To make difficult the occurrence of compaction in packed beds by a method wherein the packed beds are filled with a porous filler having a larger average particle diameter on a gas supply side than on a gas discharge side. CONSTITUTION:A biological deodorization device is provided with a treating tower 3 having a foul-smelling gas supply pipe 1 at the bottom part thereof and a treated gas discharge pipe 2 at the top part thereof.

Filed: 1987-05-06
Abstract: PURPOSE:To prevent, to the utmost, the generation of bird's beak, by forming an thermal oxide film after a silicon oxide film coated on the whole part of a substrate containing a heat-resisting mask pattern of a silicon nitride film is selectively eliminated. CONSTITUTION:After a mask pattern of a silicon nitride film 3 is formed, a silica coating film 7 is calcined. After the silica coating film 7 is calcined, the whole surface is subjected to anisotropic etching. In the state where the silica film 7 is left on the side surface of the silicon nitride film 3 on which a pattern is formed, high temperature oxidation is performed for a long time in the similar manner to prior arts. As the silica coating film 7 covering the side surface of the end-portion of the silicon nitride film 3 acts so as to easily supply oxygen to the lower semiconductor substrate 1 region, a thick oxidation film 4 is formed in the manner in which a sharp wall-surface is formed in the vicinity of the end-portion of a mask pattern. Thereby, a thick film element isolation region can be formed without forming a long large bird's beak, and the improvement of integration density is enabled.

Title: Reduction gear
Inventor: YAMADA YOSHICHIKA
IPC: F16H1/32
Filed: 1980-08-14
Abstract: PURPOSE: To achieve a compact setup of the reduction gear suitable for crawler vehicles, etc., and also improve transmission efficiency by installing a pinion which is rotated eccentrically by means of multiple number of driven gears meshed with the driving gear at the center, and rotating a hub by this pinion with a reduced rotation frequency.  
     CONSTITUTION: When a power input shaft 17 rotates, a driven gear 38 meshed with a driving gear 22 which is a part of the shaft 1s rotated. In this case, the driven gear 38 rotates on its axis because both ends of a crank pin 27 united to the driven gear 38 is supported by a block 11 consisting of a block body 1 and an end disc 9. This rotation is transmitted to a pinion 12 through a large-diametered eccentric portion 30 of the crank pin 27, and rotates the pinion 12 around the axis of the support block 11. This caused a gentle rotation of a hub 42, the internal gear teeth 43 of the hub being meshed with the external gear teeth 15 of the pinion 12, thus driving the travelling outfit of a crawler vehicle, for example.

Abstract: PURPOSE:To prevent the whole system from being shut down by placing a time- division type transmission module in reception mode except in a transmission time all the time and sending back a confirmation answer at intervals of data transfer between stations. CONSTITUTION:If the transmission line 3 between a repeater station 20b and a receiving station 20c is broken at 24 or if the transmission module 21c of the receiving station 20c enters a shutdown state, the repeater station 20b waits for an answer for a specific time and judges that abnormality occurs between the repeater station 20b and receiving station 20c unless a received answer signal is returned. Then, the transmission module 21b is placed in transmission mode and down information is sent to a transmitting station 20a. The transmitting station 20a receives the information, which reaches the repeater station 20b through the transmission module 22a, so that a confirmation answer signal to the down information is sent out. Then, the transmission module 21a is placed in transmission mode and sent data is returned in the opposite direction.
