Title: Oxygen concentration maintaining device for room air
Inventor: HASHIMOTO MASAAKI
IPC: F24F7/007
Filed: 1986-05-15
Abstract: PURPOSE:To prevent an accident from occurring due to the deficiency of oxygen and secure safety, by a method wherein when oxygen concentration in a room is lowered to or below a preset concentration value, a controller operates an oxygen- enriched air supplying device to increase the oxygen concentration in the room, and when an appropriate oxygen concentration in the room can not be recovered, combustion in a combustor is stopped. CONSTITUTION:When oxygen concentration in a room 5 is lowered and the oxygen concentration detected by an oxygen concentration sensor 12 reaches a value set in a controller 13, the controller 13 supplies power to a suction device 10 to start suction of the outside air 18. The outside air 18 is passed through a dust filter 14, and the air thus cleaned is passed through an oxygen enrichment membrane 8. The air flowing into a hood 6 is deprived of oxygen, resulting in a lowering in oxygen concentration. To prevent the air thus lowered in oxygen concentration, i.e., nitrogen- enriched air 21 from stagnating in the hood 6, an exhaust hole 15 and an exhaust fan 17 are provided at an upper part of the hood 6 to discharge the nitrogen-enriched air 21 to the exterior of the hood 6. When an appropriate oxygen concentration is not recovered in a predetermined period of time after the detection of the lowering in the oxygen concentration in the room air, combustion in a combustor is stopped.

Inventor: ABE ISAO
IPC: C01F11/32
Filed: 1985-05-24
Abstract: PURPOSE:To obtain a Ba salt having high purity and suitable for electronic material, etc., easily, by treating a Ba salt soluble in hydrochloric acid with excess hydrochloric acid to give free hydrochloric acid having a specific concentration after treatment, and subjecting the system to solid-liquid separation, thereby removing Sr, Ca, etc., which are hardly separable from Ba. CONSTITUTION:A Ba salt soluble in hydrochloric acid [e.g. BaCO3, Ba(OH)2, BaS, etc.] is stirred for 1 - several hours in excess hydrochloric acid having a concentration of >=15wt%, and reacted until the free hydrochloric acid concentration in the aqueous solution reaches 40-400g/l after the reaction. The solid is separated from the liquid by suction filtration, etc., and the resultant precipitate is dried.

Title: Stepped pulley provided with ceramic tire
Inventor: NAGATA MITSUHIRO
IPC: B21C1/14
Filed: 1979-09-03
Abstract: PURPOSE:To reduce the breakage of the ceramic tire, by forming the key hole to fix the ceramic tire to the stepped pulley at the side plane of the ceramic tire and at the main body of the stepped pulley, both at the mutually corresponding position. CONSTITUTION:The stress concentration is prevented by installing the key hole in the ceramic tire at a position far from the inner and outer circumferences of the tire. For example, the ceramic tires 5a, ..., 5d, are inserted to the outer circumference of each step of the stepped pulley's main body 4 provided with four steps. The circumferential rotation of the first step tire 5a is stopped by inserting the key 8a into the key holes 6a, 7a, respectively installed in the tire 5a and the flange 4a of the stepped pulley 4 at mutually corresponding position. Other tires are similarly fixed to the pulley 4. Besides, all tires are clamped by the flange 4a and the push plate 9. The key hole 6a of the tire 5a is located far from both of the inner circumference 5ai and the outer circumference 5ao, and the key hole 6a is formed into a shape free from the corner edge, or is preferable to be formed into a circular arc. According to this constitution, the stress concentration is moderated, even if the large speed changing force is impressed, and the generation of the fissure is prevented.

Title: Voltage measuring method by electron beam
Inventor: ITOU AKIO
IPC: G01R31/302
Filed: 1984-05-31
Abstract: PURPOSE:To take a high-precision voltage measurement without any error due to local electric field effect nor shape effect by calculating the standard deviation of the plural quantities of shifting of an S curve corresponding to plural set slice levels while varying the amplitude of the S curve, and calculating a voltage from the mean value of the quantities of shifting with which the standard deviation is minimum.

A multiple slice level control circuit 42 outputs one value alpha and a multiplying circuit 33 multiplies the data in the register 32 by alpha and stores the product in the register 22 through a maximum circuit 21. The data is compared by a comparing circuit 23 with a maximum value among S curve data in the register 22 to obtain a maximum value SMAX, and a slice level Si is determined by the circuit 42 on the basis of SMAX and stored in a register 43 successively. The registers 12 and 22 send measurement alpha-fold data to comparing circuits 13 and 23 with a signal from the circuit 42 to calculate the quantity of shifting when the data coincides with Si, so that a CPU calculates a voltage from the mean value of the quantity of shifting with which standard deviation is minimum through a difference circuit 44, mean value reference deviation circuit 44, and comparing circuit 47.

Title: Pulse constant current circuit
Inventor: ITO YUJI
IPC: G05F1/56
Filed: 1985-05-27
Abstract: PURPOSE:To obtain easily a pulse current of an optional level by supplying a constant current given from a constant current circuit alternately to a load circuit element and an artificial load circuit element via a current switching circuit. CONSTITUTION:A constant current circuit 10 delivers a constant current I corresponding to a set level to a terminal 14. While a control signal generating circuit 40 supplies the pulse given from a pulse generating circuit 41 to the gate of an FET 31 of a current path 20A as well as to the gate of an FET 32 of a current path 20B via an inverter 42. Thus both FET 31 and 32 conduct alternately and supply the constant current I sent from a stabilizing circuit 10 alternately to a load circuit element 50 and an artificial load circuit element 60. Thus a stable pulse current can be supplied to the circuit 50. In such a way, a pulse current of an optional level can be obtained easily.

Title: Apparatus for inspecting disconnection of switching circuit
Inventor: URASAKI KAZUAKI
IPC: G01R31/02
Filed: 1982-06-28
Abstract: PURPOSE:To make it possible to carry out the inspection of disconnection at low voltage, in a switching circuit connecting plural switches in series, by connecting a condenser to each switch in parallel to discriminate a logical state due to the difference in a wave form when a connecting wire is disconnected. CONSTITUTION:When a control circuit CC outputs a signal H, it is inverted by an inverter 1N1 to issue a signal L from a terminal P1 and, when all switches S1-S3 are closed, the signal of an input terminal P2 comes to L while the signal H is issued to the output side of an inverter 1N2. This signal H is detected to judge such a state that all switches are closed by a judge circuit JC. If either one of the switches S1-S3 and connecting wires L1-L4 is disconnected, the signal L is not obtained at the input terminal P2 while said signal L is issued to the output of the inverter 1N2 in a signal H state. The judge circuit JC receives this signal L to open either one of the switches or to judge the disconnection of a circuit. As mentioned above, the judge circuit JC discriminates the logical state of a detecting point to enable the judgement of the disconnection of the circuit.

Title: Time division multiplex data receiver
Inventor: KOYANO TOMOHITO
IPC: H04L69/40
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To abort invalid data due to out of synchronism. SOLUTION: When out of synchronism takes place through the production of noise 17, a layer 2 may receive continuously erroneous high level data link control(HDLC) frames when a bit string 22 is decoded. Then a threshold number is provided to number of erroneous HDLC frames received continuously and when the number is reached, out of synchronism is discriminated and succeeding reception data are aborted. When the threshold number is set to '2', a 1st frame 16c is transferred as it is and a 2nd frame 16d is aborted. Since it is conditioned that multi-frame synchronizing signal are consecutively incorrect by a specified number of times to detect out of synchronism by a layer 1, it is required to monitor F-bit 4 of lots of frames, Thus, out of synchronism is quickly detected and invalid data are aborted.
