Title: Swing piston type compressor
Inventor: UEMATSU TAKAHIRO
IPC: F04C18/32
Filed: 1995-02-06
Abstract: PURPOSE: To prevent breakage of various parts through release of an abnormal high pressure in the back chamber of a blade by a method where in a back chamber is communicated with the internal space of a compressor casing through an opening/ closing mechanism opened during an abnormal high pressure in the back chamber. CONSTITUTION: A back chamber 6 is formed in a part of the wall part of a cylinder, where a cylinder chamber 1 is formed, in such a manner to be partitioned from an internal space S between a cylinder and a compressor casing 7 and on the tip, thrusting through an oscillation guide bush 4, of a blade 5. A small communication passage 61 is formed between the back chamber 6 and the internal space S and an opening closing mechanism 8 opened in a case liquid compression is caused to occur through forward/backward movement of the blade 5 and only when the back chamber 6 is brought into an abnormal high pressure state is arranged on the side, released to an internal space S, of the communication passage 61.  When the back chamber 6 is brought into an abnormal high pressure, a plate valve 80 is opened and by releasing the back chamber 6 to the internal space S of the casing 7, an abnormal high pressure is prevented from generation and breakage of a part, such as a bush 4 and a blade 5, is prevented from occurring.

Abstract: PURPOSE: To enable to perform a smooth electric-pneumatic switching by a method wherein a regenerative brake circuit is turned to "OFF" position after the motor current of the subject electric vehicle has been attenuated at the time of switching a electric brake to a pneumatic brake.  
     CONSTITUTION: If the voltage of a filter capacitor 6 exceeds the set point when a regenerative load is broken, a signal is outputted from a detector 3 and the rise of voltage of the filter capacitor 6 is suppressed by the turning-on of a thyristor 5. The output signal of the detector 3 is also applied to a brake-current-limiting-value- pattern generating circuit 15 and a brake current limiting pattern is throtted down. Then, a signal is outputted from a counter 16 after the lapse of a fixed time and switches 2 and 10 are turned to "OFF" position. Accordingly, the smooth electric- pneumatic switching can be performed without generation of a decrease in overall braking force when the regenerative brake is switched to the pneumatic brake.

These codes are written in a fixed memory area for check of the down factor. A register part 3 sets the interuption signal sent from the part 2 and starts the counting operation of a counter part 4. Then a reset pulse transmitting part 6 actuates with the count output of the part 4 and transmits a reset pulse to reset the CPU side and also to switch the CPU side to a holding system. The CPU side carries out unconditionally an initializing routine with a reset cancel signal. In such a way, the factor of a fault is quickly analyzed.

Title: Safety system of combustor
Inventor: TAKEMOTO NAOYUKI
IPC: F23N5/24
Filed: 1979-02-20
Abstract: PURPOSE:To extinguish a combustor rapidly by a method wherein an electromagnet is energized to make an open condition comparatively in a short time on firing the combustor, and to make a magnet valve in a close condition to extinguish rapidly on an abnormal combustion time. CONSTITUTION:A controlling circuit 3 checks the tendency of electromotive force of a generator 1, which sends a signal when the electromotive force is decreased. A short circuit element 4 short-circuits both terminals of coil 2 of a solenoid valve when a signal is transmitted from the controlling circuit 3. Since this allows to flow a slight current to the controlling circuit 3 unless the electromotive force of the generator 1 is not decreased, the generator body 1 and the coil 2 of the solenoid valve are connected in series. On dropping the electromotive force of the generator 1, the load applied to the generator 1 consists the coil 2 and the short circuit element,  which causes to drop the current flowing through the coil 2, and finally unable to  flow the current to secure the open condition, which allows to become a close condition.
