Title: Dram refresh synchronous type memory doubling device
Inventor: YAMAGUCHI MASAFUMI
IPC: G06F12/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent a refreshing process from becoming out of synchronism even at system switching time by allowing a refresh request generation part of an in-operation system common memory card to send a refresh synchronizing signal to a refresh request part of a stand-by system common memory card only when the card is initialized. SOLUTION: When an other-system initialization completion signal is received within a prescribed time, clocking is ended, it is judged that this system is an in-operation system and there is the other system (standby system), and a refresh synchronous responding circuit 24 is informed of a refresh generation request and a state 17 and sends an external refresh synchronizing signal 15-o to the other system. The refresh synchronous responding circuit 24 which is informed of the request sends of a refresh counter clear request signal 26 to a refresh counter control circuit 23. A refresh counter 25 counts thereafter in synchronism with a bus clock and sends a refresh request signal 18 out to a memory access arbitrating circuit in fixed cycles.

Abstract: PURPOSE: To obtain a high denitration capacity not only at higher temperatures but also at low temperatures by changing a proper reaction temperature in accordance with the temperature change in the reaction space in a non catalytic denitration apparatus by a method in which the temperature of a non-catalytic denitration reaction space into which a reducing agent such as ammonia and hydrogen peroxide are added is detected, and the amount of hydrogen peroxide is adjusted on the basis of a specified temperature range.

In a range of 700-900 deg.C, hydrogen peroxide is added.  The temperature of a post combustion chamber 15 in which non-catalytic denitration takes place mainly is detected by a temperature detector 14, the signal of the detected temperature is sent to the flow rate controller 6, and a hydrogen peroxide aqueous solution flow rate adjuster 21 is operated by a function of preset temperature and the amount of supplied hydrogen peroxide so that a prescribed amount of a hydrogen peroxide aqueous solution is added into an urea aqueous solution.

Abstract: PURPOSE:To prevent the generation of noise by evading the reluctant ON/OFF operation of an output transistor by generating a detection pulse in respondence to the change of an address signal, adjusting the allowable operational period of an output circuit while prohibiting the operation of the output circuit in respondence to the detection pulse. CONSTITUTION:An output circuit 35 outputting reading data to the outside, address change detection means 37 and 38 generating the detection pulse in respondence to the change of the address signal, and operation prohibition means 39 and 40 prohibiting the operation of the output circuit 35 in respondence to the detection pulse, are provided. The turbulance of waveform such as ringing or the like included in the output waveform (reading data) of a sense amplifier 34 is generated during the transition period of the rise and the fall of the reading data, and this corresponding period is excluded since this transition period corresponds to the period changing the address signal. Thus, the allowable operational period of the output circuit 35 is adjusted, and the generation of noises can be prevented by avoiding the reluctant ON/OFF operation of the output transistor.

Title: Magnetic head
Inventor: ASHIDA AKIHIRO
IPC: G11B5/23
Filed: 1989-06-05
Abstract: PURPOSE:To remarkably reduce a pseudo signal output generated between a high saturation magnetic flux density material film and ferrite by forming very thinly a reaction preventive film for preventing a reaction of both of them in the boundary of the high saturation magnetic flux density material film and the ferrite. CONSTITUTION:This magnetic head is a head of an MIG type in which a Sendust alloy film 1 of high saturation magnetic flux density is used in the vicitity of a gap, ferrite 2 is used for other magnetic path, and in a boundary of both of them, an oxide film 4 of Ti, Ta, Zr or Nb is formed in 20 - 300Angstrom  thick, in 50Angstrom  thick desirably, and the alloy film 1 is formed to film thickness of 10mum. When the film thickness of an oxidation inhibiting film 4 of Ti is 50Angstrom , a pseudo signal output becomes minimum, and when the film thickness is thicker than this, a signal from this part becomes large, and a pseudo signal becomes large. On the other hand, when the film thickness becomes small, a reaction of the ferrite 2 and the sendust film 1 comes not to be suppressed enough and the pseudo signal becomes large. According to such a magnetic head, the MIG type head whose cost is lower than before can be utilized, for instance, for a head for VTR, DAT and FDD, and the magnetic head whose recording efficiency is excellent can be manufactured with higher yield than before.

Title: Alarm device for boundary surface
Inventor: BAAKUREI JIEI TARISU
IPC: B66C15/06
Filed: 1982-08-17
Abstract: A system for warning that a portion of a crane or other construction equipment has reached one of the boundaries of a working space. The system includes a laser transmitter that emits a beam which scans about a scanning axis to effect a curtain of light which defines a boundary of working space. Photosensors mounted on the outboard portion of the construction equipment generate warning signals to the construction equipment operator and other nearby personnel whenever these photosensors move into the light curtain. Additional curtain sensing equipment positioned to intercept the rotating laser beam with each cycle of rotation develops an alarm signal which activates an alarm horn and/or alarm light whenever the laser transmitter fails to provide the light curtain. The additional curtain sensing equipment is mounted an appropriate distance from the laser transmitter so that such additional sensing equipment will not interfere with the reception of the light curtain by the photosensors on the crane, and the laser transmitter and the additional curtain sensing equipment are mounted several feet above the ground to prevent foot traffic and vehicle traffic from producing false indications of a laser transmitter failure by intercepting the light curtain.
