Title: Pyroelectric infrared detector
Inventor: OCHIAI KAZUTAKA
IPC: G01J5/02
Filed: 1992-07-13
Abstract: PURPOSE:To enable an infrared detector to make self-judgment by providing a pyroelectric photoreceptor element which is positioned on the substrate of a molded interconnected device (MID) so that the central part of the element can float from the substrate and connected to an electrode for connecting earth and making the element to generate heat by conducting the electrode. CONSTITUTION:A recessed section 3a is formed at the center on the upper surface of an MID substrate 3 and element supporting sections 3b and 3c which supports both ends of a pyroelectric photoreceptor element 2 so that the central part of the element 2 can float from the substrate 3 are formed on both sides of the section 3a. When the title detector makes self-judgment, a pulsative voltage is applied across a voltage applying pin 8b. As a result, an electric current flows through an electrode pattern 4a between the pin 8b and grounding pin 8c and the pattern 4a generates heat. Therefore, the pyroelectric substance of the element 2 is heated and generates electric charges as polarization advances. Namely, when the pulsative voltage is applied across the pin 8b, the pseudoexecution of the same state as that produced when infrared detectors receive infrared rays can be carried out and the detector can make the self- judgment.

Title: Membrane nitrogen gas generator with improved applicability
Inventor: KURISUTEIAN BAABU
IPC: C01B21/04
Filed: 1993-08-24
Abstract: PURPOSE: To improve the flexibility of a membrane gaseous N 2  generator by decreasing the amt. of the gas generated from the generator and storing a high-purity product in a low demand period and increasing the amt. of the gas to be generated and mixing the gas with the stored product, thereby forming a final product in a high demand period.  
     CONSTITUTION: The high-purity gaseous N 2  is produced by disposing an air conditioning means behind a pressurizing means and sending the air from which oil, steam or the like have been removed to the membrane gaseous N 2  generator consisting of hollow fiber membranes, such as polyimide. The flow of a receiver 4 is low and the pressure in 3 is increased by the production of the generator in the low demand mode. The flow rate from the generator is decreased in accordance with the pressure read by a computer. The excess product is stored in a product receiver 2. On the other hand, the flow in 4 increases and, therefore, the pressure of 3 is so decreased as to make the production of the generator insufficient in the high demand mode. The stored product from the product receiver 2 is immediately released to the line and the producing of the generator is increased by computer control. The mixture composed of the stored product and the product from the generator is supplied in a large amt. as the final product.

IPC: F02P17/12
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent ON side voltage for causing abnormal rotation, which is generated in the secondary coil on carrying a current to the primary coil without changing the number of elements of an ion detecting circuit and a pattern in an ignition control device for an internal combustion engine with an ion detecting function which detects an ion current to determine the existence/absence of ignition/misfire and knocking, whose ion is generated in a combustion chamber when an ignition plug sparks. SOLUTION: This device includes a means for preventing generation of ON side voltage by setting the reverse voltage value of a diode 12 of an ion detecting circuit 10 to a value higher than an ON side voltage value. Though the ON side voltage is generated in the secondary coil 2 when a current is carried to the primary coil, the ON side voltage, in view of the absolute value on the secondary coil 2 low pressure side, is not generated because the reverse voltage value of the diode 11 is higher than the ON side voltage value.

Abstract: PURPOSE: To convert a furniture from a seat to a bed, by rotating a locking cam engaged with a locking surface around a pivot by the gravity, when the furniture W is inclined backward, and moving it in the direction leaving the locking surface. CONSTITUTION: While a seat back part 2 is inclined so as to take a horizontal position, the gravity causes the moment around a pivot 7, and a locking cam 6 is released from the engagement with the locking surface 9 of a seat part 1 to release the locking. Since the pin 12 of the seat back part 2 is engaged with the opposite end part of the slot 11 of the seat part 1, the further rotation is arrested, and a stable flat posture can be provided. This state can be returned to the seat posture only by pulling the seat back part 2 upward. Since the locking cam 6 is rotated around the pivot 7 to move the center of gravity under the pivot 1, the engaging cam 6 is automatically engaged with the locking surface 9 of the seat part 1 again and apt to make contact with a swollen edge part 10, and the seat part 1 and the seat back part 2 are engagingly locked again.  The locking is made firm by the complementary form of a working surface 8 and the locking surface 9.
