Title: Image forming method of electrophotography
Inventor: SAKAKIBARA SUSUMU
IPC: G03G15/047
Filed: 1980-12-15
Abstract: PURPOSE:To obtain an electrostatic image having a large contrast with a small image exposure value, by giving an even exposure to the entire surface of a photoreceptor after the image exposure. CONSTITUTION:An electrophotographic receptor is evenly charged with electricity by a charger 3 (with surface potential V1), and an image exposure A is carried out with an exposure value E3. The bright part has the attenuation of brightness (with surface potential V3) based on a characteristic curve (a); while the dark part has the attenuation of darkeness (with surface potential V2) based on a characteristic curve (b) respectively. Then the surface potential of the bright part is further lowered with an even exposure B. The dark part also has the attenuation of brightness according to a characteristic curve (a'), but the potential V2 has virtually no reduction since the attenuation of brightness of the photoreceptor is very small while the exposure value is small. The contrast of an electrostatic image set at V2-V3 during the exposure of image is increased by the even exposure of E4-E3. As a result, the same contrast as conventional is attained with a small image exposure value.

IPC: G11C7/10
Filed: 1990-07-05
Abstract: PURPOSE:To accelerate the address of a static random access memory by selectively outputting one of two sense output signals based on a specified address signal. CONSTITUTION:According to addresses A1 and A2, one cell C on a cell group CG side and one cell Cx on a CxG side are selected. Data in the C and Cx are amplified by sense amplifiers SA1 and SA2 and outputted as sense outputs dA, the inverse of dA, dB and the inverse of dB. In the state of obtaining an output Dout1 by adding the sense outputs dA and -dA from the SA1 to transistors Q17 and Q18, when changing output select signals the inverse of ODA and the inverse of ODB, the sense outputs dB and the inverse of dB are added to the transistors Q17 and Q18 and a new output Dout2 is obtained. Thus, since the output is switched by the change of the specified address and the sense output based on the data of plural cells is outputted from the sense amplifier in advance, it is not necessary for switching the output to access the cell, and the data can be outputted at high speed.

Title: Fan coil device
Inventor: FUJITA HISASHI
IPC: F24F13/32
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To enable a heat transfer load at a perimeter zone or a cold draft to be effectively processed by a method wherein air near an outer wall part of a building is sucked from a suction port, heated or cooled, thereafter the air is discharged from a blowing-out port in an upward direction. SOLUTION: Air near an outer circumference of a building where a window 4 or an outer wall 5 or the like is installed is sucked from a suction port 12 by a blowing means 16, cooled or heated by a cold water or hot water coil 15, thereafter the air is discharged from a blowing-out port 13 in an upward direction. Since the suction port 12 is arranged at an outer circumference part of an upper surface of a device main body 11, it is possible to absorb directly the air near the outer circumference, resulting in that the air does not flow into a dwelling region 6 before it is air conditioned.  In addition, the blowing-out port 13 is arranged at an indoor side rather than at the suction port 12 of the upper surface of a fan coil device main body 11, so that it is possible to cool or heat the air near the outer circumference with conditioned air discharged out of the blowing-out port 13 and further it is also possible to prevent positively the air near the outer circumference from flowing into the dwelling region 6.

Title: Inspection device for airtightness of sealed type electric appliance
Inventor: HASEGAWA KIYOTAKA
IPC: H01H49/00
Filed: 1985-08-13
Abstract: PURPOSE:To inspect airtightness automatically and accurately by deciding whether there is an air flow between the inside and outside of the case of a sealed type electric appliance put in a capsule whose internal pressure is increased or decreased based on the detected value of a strain sensor. CONSTITUTION:A capsule 30 consists of a base 31 and a cover 32, which is hinged on the base 31 through a pin 33 and opened and closed on the base 31 to form a sealed state. The strain sensor 35 is installed on the base 31 and its detector 36 is abutted with the top surface of the case of a seal relay 2 as an object of inspection. Then, the pressure in the capsule 30 is increased or decreased by the internal pressure adjusting means of an inspecting machine 25 through a pipe 37. When the relay 2 is sealed completely, the case of the relay 2 in the capsule 30 is strained and this strain is detected by the strain sensor 35, so that a decision means decides that the relay is normal. When the sealing is not perfect, on the other hand, air flows between the inside and outside of the case and the pressure in the case becomes as high as the internal pressure in the capsule 30 and the strain sensor 35 detects no strain, so it is decided that the relay is defective.

Title: Data transfer control system between magnetic devices
Inventor: MIYAGI TAKEHISA
IPC: G11B20/10
Filed: 1982-10-13
Abstract: PURPOSE:To perform efficient data transfer by interrupting data storage control a specific time later when burst-transferred data does not attain to the specific number of bytes. CONSTITUTION:If the byte counter BYC of a controller DMAC1 indicates 0 when data stored in the buffer memory of a magnetic tape device is transferred through a bus, a timer TIM is reset on the operation of the DMAC1. However, even when the BYC does not indicate 0, the DMAC1 is stopped the specific time later and then reset. At this time, either an address counter ADC nor the BYC is reset, but they are held in readiness for following block transfer and setting to the BYC is performed through a processor MPU. Further, the ADC1 is left as it is and the counted value is still effective for the next block transfer. Consequently, an idle time in an interval of burst transfer is secured and the effective data transfer is performed.

Inventor: HAMAMOTO HIROAKI
IPC: B65H23/185
Filed: 1989-07-11
Abstract: PURPOSE:To protect the thermal breakdown of the converting element of an inverter by detecting an inverter driving frequency command operated in the inverter and setting the operating conditions of tension, torque, or the like to be less than the allowed current value of the inverter at the time of very low speed. CONSTITUTION:In driving an inverter device 7 in the very low speed region, load applied to this inverter device 7 in the state of being speed-controlled is restricted to be within the capacity of an inverter converting element. In the case the inverter device 7 is controlled in tension or torque, the setting of tension or torque is restricted to be within the capacity of the inverter converting element. The inverter in the very low speed region is thereby protected, as well as the operation of an equipment can be continued as the protection of the inverter is not performed unconditionally inside the inverter. The optimum protection can be thus performed without stopping the equipment.
