Title: Detector for air and fuel ratio
Inventor: UENO MASAKI
IPC: F02D41/14
Filed: 1978-12-07
Abstract: PURPOSE: To detect the air to fuel ratio in excellent manner by detecting the voltage at the junction between air ro fuel ratio sensor and the dividing resistor at specified position of either rich or lean and changing the electric resistance of the dividing  resistor depending on this value.  
     CONSTITUTION: The air to fuel ratio sensor 20 is provided with the exhaust manihold 14 of the engine 10 of spark iginition type, it is connected to the control unit 30 and the air to fuel detector is constituted by giving electric signal to the mixed gas feeder 12. When the air versus fuel ratio A/F is at lean side greater than the theoretical air to fuel ratio ST, the lean resistance is L, and if rich position smaller, the rich resistance R is obtained. This electric resistance characteristic varies as the curves X and Y with the temperature is use or time aging. The electric resistance of the air to fuel ratio sensor 20 is changed with the contents of exhaust gas discharged from the engine 10, especially with the concentration of oxygen, the electric resistance value Re is changed with the air to fuel ratio A/F. The air to fuel ratio detection can be made with good accuracy even if the electric resistance is changed due to the temperature un use and time aging of the sensor.

Title: Horizontal unloading device for truck
Inventor: SANO MASAHIRO
IPC: B60P1/00
Filed: 1981-09-25
Abstract: PURPOSE:To prevent a cargo from stagnating in the back side of a unloading plate and to make cleaning in the back side of the unloading plate unnecessary, by separating the lower edge of the unloading plate from the bottom of a cargo box when the unloading plate is returned to an original unloading position from a position where unloading operation is completed. CONSTITUTION:When a cargo thrown into a cargo box from its top is unloaded, a roller 6 of a unloading plate 4 is passed through the lower side o a guide rail 3 and the lower surface 9' of a divergent component 9. In this connection, when a unloading plate 4 is returned to an original unloading position from a position where the unloading operation is completed, the roller 6 is rotated along  a slant surface 9'' of the divergent component 9 which is suspended by its own weight, and then the roller 6 is rotated above the upper surface of a guide rail 3.  At the front end of the guide rail 3, the roller 6 is rotated along a slant surface  3' of the guide rail and the discharge plate 4 is returned to the original unloading position. In this case, the cargo entered into the back side of the unloading plate 4 is remained on the bottom of the cargo box 1 and is never stagnated in the back side of the discharge plate 4 as the lower edge of the unloading plate 4  is separated from the bottom of the cargo box 1.

IPC: G02B5/20
Filed: 1992-05-20
Abstract: PURPOSE:To obtain a display element whose gradations can easily be controlled and which has superior display quality and superior productivity by setting a difference in film thickness between the periphery of the center of the opening of a color filter and the periphery of the opening part within a specific range at every picture element. CONSTITUTION:The liquid crystal display element consists of a glass substrate 1, a black mask 2 being the light shielding film made of a light nontransmissive material such as chromium, a color filter 3, a transparent conductive film 4, an orientation film 5, a TFT element 6, and a liquid crystal layer 7. The color filter 3 is different in film thickness between the periphery of the center of the opening part at every picture element and the periphery of the opening part and the difference is 0.2-5.0mum. This opening part is a part where optical variation of liquid crystal actually appears outside, i.e., a part of a liquid crystal display part which is not covered with the black mask 2. The film thickness difference of the color filter 3 at the opening part is set within the range since desired effect is not obtained when the film thickness difference <2mum and trouble in orientation is caused in the case of >=50mum.

Title: Memory initial setting system
Inventor: YAMAZAKI GINZOU
IPC: G06F12/00
Filed: 1979-11-26
Abstract: PURPOSE: To ensure an automatic and assured execution for both the initial setting for a volatile memory and the preservation of data to a nonvolatile memory, by discontinuing the initial setting when the initial setting is shifted to the nonvolatile memory region from the volatile memory region.  
     CONSTITUTION: Receiving the power confidence signal PC from the power supply part 107, the CPU101 starts the initial setting at the memory port A201 for the volatile memory 201. No address is designated for the novolatile memory 202 during the initial setting to the memory 201, and accordingly the address detection signal AD is not delivered from the address decoder of te memory 202. When the initial setting is over to the volatile memory region 201 and the head address of the memory 202 is designated in the next memory cycle, the detection signal AD is delivered from the decoder 301. Thus the CPU101 knows that the initial setting proceeds to the nonvolatile memory region and thus discontinues the subsequent initial setting.

Filed: 1985-07-12
Abstract: PURPOSE:To improve radiating and insulating features by a method wherein a coating of plated nickel of a Knoop hardness number 100-250 and then a ceramic coating is formed on a substrate metal surface. CONSTITUTION:On the surface of a substrate metal 10, a nickel layer 11 of a Knoop hardness number 100-250 is formed by plating. A ceramic coating layer 12 is next formed on the nickel layer 11.
