Title: Controller for variable capacity pump
Inventor: ONDA KIMIMASA
IPC: F04B49/00
Filed: 1991-06-07
Abstract: PURPOSE:To utilize the output torque to the max. over the whole pressure range by comparing the output torque of an engine with the absorption torque for a variable capacity pump, setting the absorption torque as to be max. within the range of the output torque, and outputting an instruction signal. CONSTITUTION:A controller 2 is installed, for example, on a construction machine, and when an engine 4 revolves, a variable capacity pump 6 is driven. A controller 8 always compares the output torque of the engine 4 and the absorption toque of the variable capacity pump 6, and when the latter is going to exceed the former, the controller 8 outputs an instruction signal to an solenoid proportional reducing valve 16. Accordingly, the solenoid proportional reducing valve 16 switches a control valve 12, and both the oil passages 24 and 26 are connected, and the pressurized oil in other chambers of a control cylinder 10 is discharged into an oil tank 28. Accordingly, the swash plate 20 of the variable capacity pump 6 is driven, and the discharge flow rate (absorption torque) is reduced. While, if the absorption torque is reduced both the oil passages 24 and 26 are connected, and the discharged flow rate (absorption torque) is increased.

Title: Refining method of salt water
Inventor: MATSUURA SHIYUNJI
IPC: C25B15/08
Filed: 1978-12-29
Abstract: PURPOSE: To remove oxidative halogen compounds without controlling pH by filtering the primarily treated matter after the precipitation process by active carbon then letting the same make contact with chelate resins in refining the circulating salt water of an ion exchange membrane type electrolytic cell.  
     CONSTITUTION: Sodium halide is replenished to the dilute salt water being discharged from the electrolytic cell to saturate the same, after which Na 2 CO 3  or NaOH is added to let polyvalent metal compounds sediment and separate. Thence, if active carbon is passed through the precoated filter to remove flock-form precipitate, then there is no elution of Ca, etc. even if it is an aqueous alkaline solution and even the oxidative halogen compunds may be removed. Hence, the refining process by chelate resins is progressed smoothly and the durability of the chelate resins improved.

IPC: F25D1/00
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a radiating structure of a low-cost exterior device which helps reduce the size of the device by installing sheets having many pores so as to cover all the through holes formed in an upper and a lower case. SOLUTION: This structure is constituted of an upper case 11, a lower case 12, and a sheet 13 for radiation. In the upper case 11, a plurality of through holes 14 of a specified size 'd' are so formed at regular intervals D as to let go of inside heat. The lower case 12 is of the same structure as the upper case 11 and has a plurality of through holes 14. Since a plurality of the through holes 14 are formed in a top plate and a bottom plate of the upper and the lower case, heat generated inside the cases can be let to go outside. And, the sheet 13 which has many pores is so installed on inner faces of the upper and the lower case 11, 12 as to cover all the through holes. Therefore, water and dusts can be prevented from entering the cases. Since the sheet 13 has a ventilating property, a radiating effect can be maintained inside the cases.

Filed: 1979-12-12
Abstract: PURPOSE:To prevent malfunction caused by the detour of transmitted noise by providing the 2nd IFBPF at an input stage and by leading an IF signal to this 2nd IFBPF when a noise is detected. CONSTITUTION:If an input signal is interrupted, noises amplified by a reception part increase in the IF band and noises of up to about 150kHz increase in the demodulation output of FM demodulating circuit 5. Then, detecting circuit 7 and the 2nd Schmitt trigger circuit 8 detect the nonexistence of the signal to make contact 11 of the 2nd relay 9. Consequently, diode switch 16 is changed over to select the output of the 2nd IFBPF15, which is inputted to carrier detecting circuit 2. Therefore, after the input signal is interrupted, a transmitted noise having detoured into a receiver is inputted to a carrier SQ circuit by way of the 1st IFBPF1, so that when contact 10 of the 1st relay 4 is broken, that can be corrected.

While, even if said positive half wave output exceeds the Zener voltage, the voltage applied to the lamp 14A is held to the Zener voltage by the diode 42, causing the lamp 14A to be continuously turned on. On the other hand, the capacitor 12 can be not sufficiently charged under this condition, causing misfiring to stop the engine.
