Filed: 1981-01-30
Abstract: PURPOSE:To realize an accurate transmission of data, by exchanging a message for check of transmission system between two data devices and then comparing the same data at the transmitter or receiver side. CONSTITUTION:An on-line data is transmitted between data devicesIand II containing a microcomputer 1, an acoustic coupler 3 and a telephone set 4 respectively via a telephone circuit network 5. In this case, a transmission checking message is previously transmitted from the transmitter side to the receiver side and vice versa.

The transmitter side compares its own contents of transmission with the sent-back contents from the receiver side to transmit the next data only when an agreement is obtained of the comparison. Otherwise an item of the data is transmitted twice from the transmitter side, and the contents of reception are compared at the receiver side. The receiver side transmits a retransmission request when no coincidence is obtained through the comparison and receives continuously when a coincidence is obtained respectively.

Title: Iron core
Inventor: TSUKA KAZUMASA
IPC: H01F7/06
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To suppress the breaking of a coil wound around an iron core by forming the coil winding section so that the coil winding section of the core may have an elliptic shape and the front end sections of the core may have rectangular end faces. SOLUTION: An iron core 1 has a coil winding section 1b having an elliptic cross section and both side pieces 1a and 1a having rectangular cross sections. In addition, the wire which is wound around the core 1 as a coil is coated with special paint (for example, polyurethane-based varnish, liquid paraffin-based oil unguent) by spraying the paint upon the wire with an atomizer, etc., only when the coil 1 is wound several layers at both the winding starting time and terminating time. When the cross section of the coil winding section 1b is formed in an elliptic shape, the number of turns of the coil can be increased by spraying the special paint to the wire of the coil itself in several layers only, because the several layers of the coil in the winding starting section are not damaged much.

Filed: 1978-02-10
Abstract: PURPOSE:In a method of mixed combustion of heterogeneous trash and a homogeneous fuel, to utilize effectively the energy contained in the trash bydetecting the state in a furnace by a detector and controlling the trash, fuel, and air flow. CONSTITUTION:An incinerator 2 is fed with crushed trash from a feed conveyor 11 and with a fuel (coal, heavy oil, etc.) from a fuel feed pump 12. The trash and fuel are subjected to mixed combustion while traveled on a combustion zone 3. The temperature and pressure inside the incinerator 2 are detected by a temperature detector 13 and a pressure detector 14 and fed to a computor. Temperature deviation and pressure deviation are calculated by the comparison of the measurements with an upper limit temperature, upper limit pressure, temperature set point, and pressure set point. The trash amount, fuel amount, forced draft, and induced draft are calculated on the basis of the deviations. The revolutions of motors corresponding to the calculation results  are calculated and controlled so as to keep constant the temperature and pressure inside the incinerator 2.

Title: Focusing device of single-lens reflex camera
Inventor: IMAI TOSHIHIRO
IPC: G03B19/12
Filed: 1978-02-10
Abstract: PURPOSE:To achieve the reduction in the number of parts and the improvement in focusing accuracy by forming an incident part to a quick return mirror. CONSTITUTION:The mirror face 12 of the portion on the optical axis of the quick return mirror 11 of a single-lens reflex camera is partly removed to allow the light from the photographic lens to enter the inside of the parallel plane glass plate constituting the quick return mirror 11. After it is repeatedly reflected on both top and bottom surfaces, it is emitted toward a photo detector 13 from the end part. The optical path entering the inside of the glass plate from the transparent part of the quick return mirror 11 until reaching the photo detector 13 is made the distance which is optically equivalent to the distance until the light having passed the photographic lens reaches the film plane and focusing is accomplished through photometry by the photo detector 13. Thereby, the incident part for focusing is formed to the quick return mirror 12 and the passageway of the light until reaching the photo detector 13 is confined only within the mirror 12 and therefore the intended object is achieved.

Filed: 1983-01-31
Abstract: PURPOSE:To make the temperature at ceiling portion and that at floor portion nearly uniform at all times by a method wherein both the heating with heat performed at the early stage of room heating and the heat utilization operation to utilize the heat at the upper portion in a room developed by said heating are made possible. CONSTITUTION:When the heating of a room 4 is done because of low temperature in the room 4, a solenoid valve 20 is open and a solenoid valve 22 is closed by means of a temperature detecting element 23 which detects said low temperature. Consequently, refrigerant sequentially flows through a compressor 7, a second heat exchanger 17, the solenoid valve 20, a first heat exchanger 15, a throttling resistance part 9, an outdoor heat exchanger 8 and back to the compressor 7. At this time, the first and second heat exchangers 15 and 17 act as condensers while the outdoor heat exchanger 8 acts as an evaporator and the room 4 is heated with heat by operating blowers 16 and 18. When the temperature at the upper portion in the room 4 reaches a predetermined temperature, the solenoid valve 20 is closed and the solenoid valve 22 is open by means of the temperature detecting element 23. Consequently, because refrigerant flows a course indicated with a dash line and accordingly a throttling resistance 19 is brought into action while the outdoor heat exchanger 8 and the throttling resistance part 9 are brought out of action, the second heat exchanger 17 acts as a condenser while the first heat exchanger 15 acts as an evaporator. A bypass circuit 21 bypasses the outdoor heat exchanger 8 and the throttling resistance part 9.

Title: Filter device for heat exchanger
Inventor: YAMAMOTO KEN
IPC: F25B49/02
Filed: 1990-01-24
Abstract: PURPOSE:To prevent the clogging of fluid passages formed in a heat exchanger by a method wherein the title device is provided with a filter, filtrating fluid, a clogging detecting means, detecting the clogging of the filter, and an alarming means, notifying the clogging of the filter to the outside of the device. CONSTITUTION:Refrigerant, expanded adiabatically in an expansion valve, flows through an inlet pipe 9. In this case, dust, products by corrosion and the like, which are contained in refrigerant, are arrested by a filter 3 attached to the inside of the inlet pipe 9. The refrigerant, filtrated by the filter 3, is gasified by heat exchange between ambient air upon flowing through the refrigerant passages of respective flat tubes 6 from an inlet header 8 and flows out of an outlet header through an outlet pipe. When the filter 3 is clogged in accordance with the operation of a refrigerating cycle, the pressure of the refrigerant, which is applied on the filter 3, is increased and, therefore, the filter 3 is pushed and deformed toward the side of the inlet header 8. In this case, a strain gauge 4, attached to the filter 3, changes the deformation of the filter 3 into the change of an electric resistance and outputs it to an alarming device 5.

Abstract: PURPOSE:To improve magnetic efficiency by forming a core cutting a drawn material. CONSTITUTION:A core 1 is a magnetic material such as electromagnetic soft iron. A hoop material formed to an approximately U-shaped cross section by drawing by a central piece 1e and both projection pieces 1a, 1b projecting at both end parts of the central piece 1e is cut to a specified thickness.
