Title: Heat exchanger equipped with fin
Inventor: TANAKA HIROYOSHI
IPC: F28F1/12
Filed: 1984-04-19
Abstract: PURPOSE:To obtain a high heat transfer rate by bending the airflow path of the heat exchanger equipped with fins with a proper radius of curvature. CONSTITUTION:Flon refrigerant, flowing in a copper tube 1 in the condition of two-phase flow, transfers the heat thereof to fin collars 2, wavy fins 3 and cut- ups 4, formed by aluminum, and effects heat exchange between air flowing from the direction of arrow sing X in the diagram. In this case, the flow of air is regulated in the flow direction thereof by the curve of the wavy fins 3 and the flow direction is changed gradually. The change of speed element of the airflow induces secondary flows and generates local vortexes. This flow increases the vertical component of airflow with respect to the wavy fin 3, therefore, the heat transfer rate is improved remarkably. Furthermore, when these vortexes collide against the fin collars 2 or the heat transfer tubes 1 under riding on deflected main stream, strong horseshoe type vortexes are generated around the fin collars 2 or the heat transfer tubes 1 and the heat transfer rate in the rear streams of the heat transfer tubes may be increased remarkably.

IPC: C22C1/00
Filed: 1979-06-25
Abstract: PURPOSE: To obtain an amorphous magnetic material having magnetic characteristics about equal to those given by annealing in a magnetic field as rapidly cooled and superior toughness by rapidly cooling molten metal or molten alloy in a magnetic field to make it amorphous.  
     CONSTITUTION: A mother alloy having the composition of Fe 80 P 15 C 7  is put into quartz nozzle 1 and melted by heating with high frequency induction coil 3. Melt 2 is sprayed upon the outer surface of copper roll 5 rotating at a high speed to manufacture amorphous ribbon 4 by rapid cooling. At this time, the sprayed melt is cooled in magnetic field 7 formed by placing permanent magnets 6 until ribbon 4 is cooled to at least the Cruie point or below. Ribbon 4 is rapidly cooled in field 7 almost parallel with its longitudinal direction. As a result, the obtd. amorphous alloy ribbon can be bent by 180° and has superior mechanical characteristics since it does not pass through an annealing process. In case the above-mentioned cooling process is carried out in a magnetic field almost perpendicular to the longitudinal direction of ribbon 4, ribbon 4 having similar characteristics is obtd.

Title: Absorption type cooling/heating machine
Inventor: FURUKAWA TETSUO
IPC: F25B15/00
Filed: 1995-04-05
Abstract: PURPOSE: To eliminate trouble such as the natural movement of an absorbent liquid, which is caused due to a siphon principle when the operation of an absorption type cooling/heating machine is stopped, by connecting an intermediate portion of an absorbent liquid transfer pipe, which is in a position higher than the level of the absorbent liquid in an absorber, to a gaseous phase part of a regenerator with a bypass pipe and mounting an on-off valve on the way of the bypass pipe. CONSTITUTION: In a state that operation is carried out i.e., in a state that an absorption cycle is performed, a solution pump provided on the way of an absorbent liquid transfer pipe 3 is operated, and the absorbent liquid is transferred from an absorber 1 into a regenerator 2. On the other hand, in the case where the operation of an absorption type cooling/heating machine is stopped, a solenoid on-off valve 6 is opened after stopping the operation of the solution pump. Then, the absorbent liquid in the absorbent liquid transfer pipe 3 drops and moves into the regenerator 2 through a bypass pipe 5. That is, since a gaseous phase part is formed at an intermediate portion of the absorbent liquid transfer pipe 3, the absorbent liquid in the absorber 1 is prevented from naturally moving into the regenerator 2 even in the case where the operation of the solution pump is stopped.

Title: Grindstone dressing device

IPC: B24B53/02
Filed: 1989-03-30
Abstract: PURPOSE:To dress and remove only projections of a grindstone via an appropriate dress quantity by providing a means which detects that a dresser is brought into contact with the surface of the grindstone except projections and outputs a signal driving a longitudinal feed means. CONSTITUTION:A dresser 16 is moved based on the combined information of the information on end positions of projections, e.g. ear sections 1b and 1c, of a grindstone 1 and the information when the dresser 16 is brought into contact with the grinding surface of the grindstone 1, and only the ear sections 1b and 1c of the grindstone 1 are dressed and removed. The strip grinding surface of the grindstone 1 is not dressed, thus grinding can be performed by the grindstone 1 without damaging a strip. The dresser 16 itself is brought into contact with the grindstone 1 and directly measures the depth of the ear sections 1b and 1c, thus the ear sections 1b and 1c can be dressed via an adequate dress quantity and correctly removed without being affected by the elastic deformation of the grindstone 1 and the thickness fluctuation of the strip.

Title: Spread spectrum transmitter and receiver
Inventor: IMOTO KATSUYUKI
IPC: H04J13/00
Filed: 1982-05-14
Abstract: PURPOSE:To realize stabilized communication, even if the frequency of a transmission carrier is instable, by controlling at a receiving side to make the central frequency of BPF, which is installed before the demodulator of receiver, coincident with the frequency to be inputted to it. CONSTITUTION:A received signal Vi is mixed by a mixer 12 with a signal V, which has a local oscillation frequency fl, of an oscillator 13 for voltage control and becomes Vif. The signal Vif is picked up its component of fi-fl-fel (fel is the clock frequency of a transmitter) by a BPF and inputted to a phase detector 17. To the other side of input of the detector 17, a signal Vr, which has a reference oscillation frequency fi'-fl'-fel, is inputted. The detector 17 compares both inputted signal components, and, if there is a difference between frequencies, the output of the comparator 17 is made feedback to the oscillator 13 via a LPF14 to control the frequency fl of the oscillator 13 so that it becomes fi'- fl'=fi-fl. As a result, a stabilized transmitter-receiver for spectrum spread communication is realized even if the frequency of carrier of a transmitter is instable.
