Title: Finned heat exchanger
Inventor: OBATA MAKOTO
IPC: F25B39/02
Filed: 1984-12-27
Abstract: PURPOSE:To permit to uniform the layer of frost between fins, elongate a time until a space between fins is blockaded by frost and reduce the number of defrosting operation by a method wherein respective fins of the groups of fins, arranged in parallel with a given space and air flows therebetween, are corrugated and the pitch of corrugation is set so as to be shortened stepwisely toward the outflow direction of the airflow. CONSTITUTION:The pitch Pf1 of corrugation of the corrugated fin 4 at the inflow part of airflow is long, therefore, disturbance of airflow is not generated easily and the difference between absolute temperature of ambient air, related to the amount of frosting, and saturated humid air corresponding to the temperature of heat exchanging heat transfer surface becomes small. As a result, the thickness of layer 3 of frost at the air inflow part becomes thin. The gradually cooled and dehumidified air generates the disturbance gradually since the pitch Pf is shortened step-wisely toward the outflow direction of air, accordingly, the layer 3 of frost is formed as the result of heat exchange between the cooled and dehumidified air. According to this method, the thickness of layer 3 of frost on the surface of the corrugated fin 4 becomes uniform, a space between fins will never be blockaded even the fins are frosted, the width of ventilating path may be secured widely and the number of defrosting operation may be reduced.

Title: Device for removing article from vessel and its method
Inventor: SAKURAZAWA HATSUO
IPC: B65G47/68
Filed: 1990-10-19
Abstract: PURPOSE:To automatically and efficiently remove the articles from a vessel in a serial flow of the articles to the next process, by passing the vessels with the articles through a removal area of the articles, in which the transfer way is twisted. CONSTITUTION:When a freezing vessel V reaches a foods-removing section S of a transfer way W, the front of the freezing vessels V is low at the right side and high at the left side in the first half but on the other hand, the rear part keeps a specified level without variation and hence, the freezing vessel V varies to rise to the front at the right side but to lower to the front at the left side. Therefore, the freezing vessels V are twisted around the diagonal line as a symmetry line. Next, when the freezing vessels V are transferred to the second half, the front of the freezing vessels is returned to the original level but the rear part of the vessels is low at the left side and high at the right side. In this time, the vessels vary to rise to the rear at the right side and to rise to the front at the left side. Since the frozen foods in the freezing vessels are not flexible, they can not follow the deformation of the freezing vessels and hence, the foods are removed from the vessels.

Title: Correlation type speedometer
Inventor: TAGO KEIICHIRO
IPC: G01P3/80
Filed: 1984-12-27
Abstract: PURPOSE:To obtain a correlation type speedometer which enables accurate measurement even for upstream side and downstream side detection signals changing greatly, by varying voltage division ratios of voltage division circuits on the upstream and on the downstream sequentially with a plurality of comparators to hold the magnitudes of first and second signals within an allowable input range of a multiplication circuit. CONSTITUTION:Though the amplitude of the upstream side detection signal 1a becomes larger, the voltage division ratio of a voltage division circuit 13 is automatically controlled with comparators CM11, CM12 and CM13 to hold the amplitude of the first signal 6a inputted into a multiplication circuit 9 within an allowable input voltage range while the voltage division ratio of a voltage division circuit 14 is controlled to that equal to the voltage division ratio of the voltage division circuit 13 simultaneously with the voltage division ratio of the voltage division circuit 13. Thus, accurate measurement can be done regardless of significant amplitude of the detection signals 1a and 2a. This also assures a stable measuring operation free from any sharp changes in the detection signal 1a due to the action of delay circuits 16, 17 and 18 to operate the comparator CM11, CM12 and CM13 sequentially.

Title: Dry desulfurizing method
Inventor: OGAWA HIROSHI
IPC: B01D53/34
Filed: 1986-11-26
Abstract: PURPOSE:To simultaneously perform desulfurization and dust removal of reducing gas in the same vessel by passing sulfide-contg. reducing gas jetted with iron oxide powder through a deposited layer of iron oxide formed on the surface of a filter consisting of porous ceramic. CONSTITUTION:An absorbent layer 2 is formed by depositing iron on the surface of a filter 1 consisting of porous ceramic. H2S incorporated in reducing gas is absorbed and removed by the following reaction equation when it is passed through the absorbent layer 2 consisting of iron oxide. Fe2O3+2H2S+H2 2FeS +3H2O. Since the particle diameter of the used absorbent is regulated to 10-100mu and is very small, the surface area per unit volume is large and also the contact time is made short and the usage of a desulfurizing agent is reduced. Further in the above-metnioned reaction, since only the surfaces of iron oxide particles are allowed to react, the smaller the particle diameter is, the larger the absorption capacity per unit volume is made and the utilization factor of iron oxide is enhanced.
