IPC: G03G15/00
Filed: 1984-02-13
Abstract: PURPOSE:To facilitate assembling and to improve work efficiency by solidly forming a manifold portion and a transport conveyer bearing member together with a base frame with plastics and making it possible to fix the bearing without a screw. CONSTITUTION:A paper transport apparatus comprises a base frame 1, and a manifold portion 2, the front bearing members 8, 8 and the back bearing members 12, 12 which are formed integral with the base frame 1, wherein a transport belt 20 is inclined in such a manner as to be higher on the front side. By the relation between tension and angle of inclination of the belt 20, bearings 11, 15 are positioned at the respective bearing members 8, 12 without any other fixing means such as crews or the like. A cover is stuck to an opening formed on the lower surface of the manifold portion 2 to prevent leakage of air. The number of projections 3 of the manifolds 2 and the sizes of its inside volume and the opening 4 are determined according to the size of paper to be used. Thus, the time required for assembly work can be reduced by a large margin so that the cost goes down.

Title: Semiconductor storage device
Inventor: HIRAI HISASHI
IPC: H01L21/8242
Filed: 1987-02-02
Abstract: PURPOSE:To make a pause time longer and reduce the scattering of the pause time by a method wherein impurity concentration in a drain region coupled with a capacitor is rendered lower than that in a source region. CONSTITUTION:An LDD transistor is so constructed that impurity concentration is lower in a drain region 6 coupled with a data storage capacitor than in a source region 7. This results in a lowered impurity concentration at the edge of an insulating film isolating elements in the vicinity of the capacitor, which brings about a reduction in the leak into a substrate. In this way, a pause time may be made longer and scattering is reduced in the pause time.

Also a vertical movement solenoid valve 66 is switched over to expand a flexible tube 43 so as to raise a vertical movement brake rail 44 and apply brake by frictional force. Then, when the longitudinal movement rail 12 is moved backward, the load 7 remains at the forward movement position together with the vertical movement brake rail 44, and the longitudinal movement rail 12 only is moved backward and returned back to the original position.  Thus the load 7 only is moved forward by one stroke, and the longitudinal movement rail 12 and vertical movement brake rail 44 are returned back to the original positions.

Title: Reception discriminator
Inventor: IWASAKI HARUYA
IPC: H04L27/18
Filed: 1993-02-12
Abstract: PURPOSE:To discriminate reception of a signal in a time considerably shorter than conventional especially in the case of very long intervals of unique words by monitoring the power ratio of the I-axis signal to the Q-axis signal of a BPSK demodulated signal. CONSTITUTION:I and Q signals of an orthogonally detected demodulated signal are squared by multipliers 1 and 2. Outputs of multipliers 1 and 2 are integrated by integrators 3 and 4. The output of the integrator 4 is multiplied in a multiplier 5 by a preliminarily determined multiplier A to convert this calculation to a form of multiplication, and this output is compared with the output of the integrator 3 by a comparator 6. When the ratio (I/Q) of the output of the integrator 3 to that of the integrator 4 is higher than a prescribed threshold '2', it is discriminated that a signal is received; but when it is not higher, it is discriminated that a signal is not received.

Filed: 1982-02-16
Abstract: PURPOSE:To make the air conditioning device compact, by providing a bimetal air direction changing vane at an outlet port of heat exchanged air, and bowing out the warm air downward and the cool air upward. CONSTITUTION:The air direction changing vane 8 is formed to a plate shape by sticking two sheets of metal plates 8a and 8b having different heat expansion coefficients. Both ends thereof are fixed to the both side walls facing each other of the outlet port 3 through a shaft or the like. The expansion coefficient of the metal plate 8a is made larger than that of the metal plate 8b so that the vane is curved with the longitudinal direction as an axis. At the time of cooling operation, the air cooled by a heat exchanger 5 is blown out of the outlet port 3. Since the vane 9 is cooled, the flat plate state or slightly curved state in the upward direction is kept, and the cool air is blown in the horizontal direction. At the time of warming, the vane 8 is gradually curved downward with the increase of the air temperature, and the blowing direction is gradually changed to the downward direction.

Title: Half tone processing method
Inventor: YAMADA AKITOSHI
IPC: G06T5/00
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To reduce artifact dots that become a factor of image deterioration and to improve the image quality of half tone by changing the weight and/or threshold of error diffusion based on an output error or based on image data and an accumulative output error. SOLUTION: A CPU 100 sends multivalued image data that is obtained by executing half tone processing due to error diffusion by a host processor 23 having high throughput to a printer 30 through a two-way communication line 106 and makes it printed according to a program stored in a printer driver 114 of a disk 25. In such a case, the half tone processing calculates an output error of difference between a desired output variable density level and an actual print value based on comparison of attentional pixel value with the sum of its accumulative errors, weights based on the result and diffuses and distributes the output error to adjacent pixels of the attentional pixel. It is transmitted to the printer 30 after the full image is subjected to the half tone processing. Furthermore, the weighting performs cyclic change in middle, right and left directions.
