Title: Controlling valve
Inventor: MOROZUMI EIICHI
IPC: G01M3/28
Filed: 1981-01-28
Abstract: PURPOSE:To enable for the valve to refuse to be open in the presence of leakage by a method wherein the leakage of gas under the closed state of the valve is checked by a flow sensor equipped at the secondary side of the valve which is used for controlling gas supplying to a burner. CONSTITUTION:The Hall element 33 of the flow sensor 3 produces one pulse with every one rotation of an impeller 31 and sends said pulse to a controlling circuit 4. The controlling circuit 4 confirms whether the Hall element 33 sends out pulse signal or not for the fixed time since the time when the circuit 4 receives a starting signal from outside. The controlling circuit 4 does not supply the prescribed driving signal to the coil 23 of an actuator 2 to perform the action to open a valve body 14 until the confirmation that no pulse signal is sent from the Hall element 33 is established. However, if pulse signal is sent from the Hall element 33 for said fixed time, the controlling circuit 4 does not issue any driving signal and accordingly, the valve body 14 refuses to be open.

Title: Low temperature regeneration type moisture absorbing element
Inventor: TAKAMIYA HIROYUKI
IPC: B01J19/32
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain an element which is highly moisture absorbing and discharging and has high speeds of moisture absorption and discharge to be regenerated at a low temperature by a method in which a highly moisture absorbing and discharging polymer containing salt type carboxylic groups is made to be a main component, gas penetration channels are formed, and a regeneration temperature which is required for removing moisture-absorbed water is specified. SOLUTION: A highly moisture absorbing and discharging polymer containing 2.5-10.0meq/g of a salt type carboxylic group is made to be a main component. Gas penetration channels are formed, and a regeneration temperature required for removing moisture-absorbed water is made to be 110 deg.C or below. In a method to obtain the highly moisture absorbing and discharging polymer, a monomer having a salt type carboxylic group, e.g. acrylic acid, is homopolymerized or copolymerized with another copolymerizable monomer, e.g. vinyl chloride. If the polymer is in the form of fibers, various types of processing are possible to make various kinds of elements equipped with gas penetration channels. In this way, because of a small size, a low regeneration temperature, high safety, and saved energy, it can be used for dehumidification, drying, etc., for household use.

Title: Controller for electric rolling stock
Inventor: KOJIMA SHIGERU
IPC: B60L9/18
Filed: 1983-01-25
Abstract: PURPOSE:To reduce the size of a controller for an electric rolling stock by dividing the speed range of the electric rolling stock into a plurality of speed zones so that the number of pulses corresponding to the respective speed zones decreases as the speed increases and avoiding the continuous operation in a high modulation frequency at the constant speed operation time, thereby alleviating the thermal load of the components of an inverter. CONSTITUTION:A constant speed operation discriminator 23 discriminates as a constant speed operation when the variation in the frequency FINV of an inverter is, for example, within 5Hz for 30sec so that its output becomes a high voltage. As a result, the frequency FINV of the inverter is inputted through an AND circuit 24 to a pulse mode converter 25. This converter 25 outputs switching signals of pulse mode 45 to 27, 27 to 15, 19 to 9, 5 to 3 to a modulator 26 when the inverter frequency is, for example, 11-18Hz, 18-28Hz, 33-38Hz, or 49- 52Hz, and the modulator 26 produces a gate signal corresponding to the pulse modes. In this manner, the components can be designed to be small in thermal capacity, thereby reducing the size and weight of the controller.
