Title: Heat exchanger
Inventor: YAMADA YUKIO
IPC: F28F13/14
Filed: 1979-04-27
Abstract: PURPOSE: To realize a substantial increase of a volume of heat exchange by a method wherein both hot fluid and cold fluid are flowed toward opposite directions at the inner and outer parts of the heat transmitting plate to perform a heat exchanging of both fluids, and a thermal transmitting heat in the heat transmitting pipe is increased near at a pinch point.  
     CONSTITUTION: When a power generation is performed by utilizing a terrestrial heat or waste heat, hot water or other hot fluid H is flowed to the heat transmitting pipe 2 in each of the heat exchangers 1aW1f, a cold fluid L such as fleon etc. is flowed outside of the heat transmitting pipe 2 to perform a heat exchanging operation between both fluids. In this case, it is possible to have a substantial increase of a volume of heat exchange by increasing a thermal conductivity in the heat transmitting pipe 2 only at adjacent to the pinch point. As means for increasing said thermal conductivity, means for making the surface of heat transmitting plane rough is employed. A scope or range to increase a thermal conductivity should be set at such a range as an increase of a power driving force of a pump which is caused by an application of said means being decreased lower than an increase in output from the turbine, etc.

Title: Zoom lens system
Inventor: FUKUSHIMA SHO
IPC: G02B15/16
Filed: 1989-03-03
Abstract: PURPOSE:To obtain a compact zoom lens system which employs an easy movement format for zooming by composing the system of 1st-4th lens groups in order from the object side, using two positive and negative plastic lenses in one of the groups, and satisfying specific inequalities. CONSTITUTION:The system is constituted of the 1st lens group (I) with positive refracting power, the 2nd lens group (II) with negative refracting power, the 3rd lens group (III) with positive refracting power, and 4th lens group (IV) with negative refracting power. Then when the system is zoomed from the shortest-focal-length end to the longest-focal-length end, the gap between the 1st and 2nd lens groups (I) and (II) increases and the gap between the 3rd and 4th lens groups (III) and (IV) decreases. Further, the two positive and negative plastic lenses are used in one group and the inequalities I-IV are satisfied. In the inequalities I-IV, PHI1-PHI4 are the composite refracting power values of the 1st-4th lens groups, PHIi is the composite refracting power of the (i)th lens group including the two plastic lenses, and PHI8 is the composite refracting power of the two plastic lenses. Consequently, the compact lens system which employs the easy movement format for zooming is obtained.

Title: Manual driving type copying device
Inventor: TANIWAKI MICHIO
IPC: H04N1/107
Filed: 1989-03-03
Abstract: PURPOSE:To input both character data and halftone data in a satisfactory state by providing a changeover switch to output a binarization reference signal for character mode or a binarization reference signal for pseudo gradation input based on a mode specified by a reading mode means. CONSTITUTION:A digital signal outputted from a dither pattern generation circuit 106 is converted to the corresponding analog signal by a D/A conversion circuit 107 and outputted as the binarization reference signal for halftone. A comparator 109 compares the binarization reference signal for halftone with a video signal and binarization is executed. Thus, by designating the halftone mode by a character/halftone switching button 108, a circuit is switched by a changeover switch 108 and the inputted picture information are processed as the halftone data. The dither pattern is formed as a pattern, which can execute 75% and 50% reduction without the deviation of gradation by simply thinning a prescribed position.

Title: Speed control device of differential centrifugal dehydration machine
Inventor: HAMAMOTO HIROAKI
IPC: H02P5/74
Filed: 1993-03-15
Abstract: PURPOSE:To avoid an unusual increase in the regenerative power of a motor on a regenerative operation side when a power supply for a differential centrifugal dehydra tion machine which is powered by motors, one of which is in a power running mode and the other of which is in a regenerative running mode and at the same time, dehy drating, has recovered from a short time power supply failure. CONSTITUTION:If the speed of a motor 22 for a differential governor is accelerated during a power supply failure, a signal switching device 33 activates an instantaneous power supply failure frequency setting device 32 in which a higher value is set during the recovery of power supply. Therefore, the deviation range between the speed of the motor for a differential governor and a command value of frequency for the differential governor is narrow, so that a regenerative power can be restricted. The command value of frequency for the differential governor at a further higher level is gradually restored to an original value by action of a means for calculating a reduced speed. Consequently, the speed of the motor for the differential governor is restored to an original speed in a maintained deviation range, in accordance with a change in the command value of frequency for the differential governor, and thus the regenerative power is well controlled.

The emitted signal light reflects on the boundary face with the material 5 and is sent by multiplex transmission in the axial direction of the optical fiber. Since the PC resin constituting the material 4 is set at 1.7-2.5X14<4> optimum mol.wt., the scattering loss can be minimized.
