Patent JP-H02237637-A (JP)
Title: Production of active ion
Inventor: MURAMATSU KAZUMI
IPC: B01J19/08
Filed: 1989-03-10
Abstract: PURPOSE:To efficiently produce active ions by introducing a gas containing ozone to a discharge zone and rendering the gas to a plasma state. CONSTITUTION:An oxygen-contg. gas is fed by a blower 21 into an ionizer 22, where the gas is changed into a ozone-contg. gas. The mixture gas is then sent to the discharge zone 23, where arc discharge is caused between the electrodes 33 when electric power is applied on the primary coil of the transformer of the discharge unit from the power supply 38. In the arc discharge zone, electrons are efficiently generated due to the operation of reactor 36 and capacitor 37. Therefore, the gas introduced into the discharge zone is rendered to a plasma state at low temp., in which ozone is decomposed to increase the amt. of active ions. These ions can give impacts on plants grown in a greenhouse.

Title: Air-fuel ratio controller for internal-combustion engine
Inventor: NAKAJO YOSHIKI
IPC: F02D41/14
Filed: 1985-03-22
Abstract: PURPOSE:To aim at improvement in a responsive speed ever so better, by installing each air-fuel ratio sensor at both upstream and downstream sides of a catalytic converter and at the time of compensating a delay time at the time of air-fuel ratio control by the sensor at the upstream side with output of the sensor at the downstream side, making a possibility that the delay time becomes more than the specified time limitable. CONSTITUTION:Each of air-fuel ratio sensors 13 and 15 is installed at both upstream and downstream sides of a catalytic converter in an exhaust system, and each output of these sensors 13 and 15 is compared with each of specified values VR1 and VR2 by comparing devices A1 and A2. According to the compared result to the comparing device A2, a delay time TDR delaying the compared result of the comparing device A1 is calculated by an operational device B, and when this is judged as being larger than the specified time TR2 by a comparing device C, the delay time TDR is subtracted as much as the specified value tR. And, at a delaying device E, the compared result of the comparing device A1 is delayed according to output of an adjusting device D, and an air-fuel ratio compensation value FAF is found by an operational device F on the basis of the compared result after delaying, then further this compensation value FAF is adjusted for increase or decrease by a varying device G on the basis of output of the comparing device C.

Title: Method for verifying equipment data
Inventor: YOKOMORI TADASHI
IPC: H05K13/00
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To create optimum equipment data by calculating part mounting movement and cassette movement based on the equipment data or the like of equipment in operation, and obtaining a part mounting travel and a number of cassettes moved based on tact calculation parameters for each piece of mounting equipment to calculate a part mounting time. SOLUTION: Equipment data 1 on equipment actually in operation to mount parts on printed boards or equipment data 1 with optimum mounting order determined using a CAM system is acquired as input data (2). Based on this equipment data, part mounting movement and cassette movement are calculated (3). Subsequently, based on the cycle time calculation parameters for each piece of mounting equipment, the part mounting travel and the number of cassettes moved are obtained for each piece of mounting equipment (5). From variation in the part mounting travel and the number of cassettes moved for each piece of mounting equipment, the part mounting time is calculated. Thus, mounting order can be determined for each piece of mounting equipment so that the moving loss is minimum.

Title: Camera
Inventor: MIKOSHIBA HIRONOBU
IPC: G03B7/16
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To set appropriate exposure and to restrain camera shake by making the emitted light quantity of a flash smaller than the maximum emitted light quantity, and setting a diaphragm value at the time of emitting light to a value on an open side further than the appropriate diaphragm value at the time of photographing a short-distance subject while emitting flash light in a self-portrait photographing mode. SOLUTION: According as a CPU 1 sets the self-portrait photographing mode, a flash circuit 4 adjusts the emitted light quantity of the flash 4a to be small, for example, 1/2. Furthermore, the flash circuit 4 shifts light emitting timing so that the flash 4a emits the light at the point of time when the open aperture of a diaphragm combined with a shutter 9a becomes F2 in order to compensate the exposure emitted light quantity made smaller according as the emitted light quantity of the flash 4a is adjusted to be small, for example, 1/2. Thus, emitted light quantity of the flash 4a is made small and the light emitting timing is changed so that the light is emitted when the open aperture comes closer to an open end according as the self-portrait photographing mode is set.

IPC: G01N30/96
Filed: 1981-04-17
Abstract: PURPOSE:To adsorb heavy metals to a chelate ion exchange filter paper quickly and to concentrate said metals, by adding a fixed quantity of sample water and a buffer solution into a regulation vessel and heating the resulting solution for a fixed time and hereafter, moving it into a filter vessel setting filter paper and filtering it. CONSTITUTION:A regulation vessel is soaked into a water bath in a boiling state to heat the vessel 1. Next, a fixed quantity of sample water is poured 2 into the vessel. Continuously, a fixed quantity of a pH buffer solution is charged as shown by 3 in order to keep pH of the sample water constant and heating 4 is carried out for about ten minutes. Next, the heated sample water is charged into a filter vessel setting filter paper at the lower part and take-out 5 of the sample liquid is carried out and then, filtration 6 is carried out so that the filtration is finished in 20-30min by filtration under reduced pressure. The filtration is carried out sufficiently even when suction force is not so high as the normal temperature because adsorbing reaction is accelerated by increasing a liquid temperature to 96 deg.C by heating 4 and the viscosity of the sample water is decreased.

Filed: 1991-03-20
Abstract: PURPOSE:To obtain good fixability without impairing a preservable property even with low heat energy by using a bisphenol F type epoxy resin having a specific repeating unit as the essential component of the above toner. CONSTITUTION:The bisphenol F type epoxy resin having the repeating unit expressed by formula I is used as the heat fixing type toner essentially consisting of the epoxy resin.

Filed: 1985-03-20
Abstract: PURPOSE:To improve the compression efficiency by forming the piston ring to be flush with the upper endface of piston thereby reducing the annular space between the innercircumferential face of cylinder and outercircumference at the upper end of piston thereby increasing the delivery of compressed air. CONSTITUTION:A piston ring 21 is mounted through an O-ring 22 in a ring groove 7B of piston 7. The piston ring 21 is made of self-lubricant material such as Teflon and formed with thick annular section 21A and thin annular section 21B extending from the outercircumference of said section 21A axially upward along the outercircumference at the upper end of piston 7 to choke the annular space between the upper end outercircumference 7D and the inner circumferential face of the cylinder 2. Here, the upper endface of the thin section 21B is made flush with the upper endface 7A of the piston 7. Consequently, the air compressed in the cylinder 2 is prevented from storing between the inner circumferential face of cylinder 2 and the upper end outercircumference 7D thus to achieve the intended purpose.
