Title: Powder painting method of print board having metal core
Inventor: KOKUBU TAKAYOSHI
IPC: B05D1/22
Filed: 1979-08-21
Abstract: PURPOSE: To prevent a handle portion from paint adhesion by blowing a dried air to a handle portion in the process of powder painting a metal substrate plate having a handle portion by a fluidized immersion method.  
     CONSTITUTION: A base metal plate 1 for a print board fabricated by subjecting a metal plate to press punching along with handle portions 2, 3 is suspended on a support pin 5 of a leading end of a hanger 4 after preheated and subjected to the immersion powder painting. In carrying out a printed wiring, the handle portions 2, 3 are used to fit a position of a negative for printing, but, if a paint is adhered to the handle portions 2, 3, a good adhering condition of a photosensitive film or a negative for printing is not obtained, accordingly a dried air is blown to the handle portions 2, 3 from a nozzle 7 during the painting. Thereby, a paint is prevented from being flowing out and adhered and, in printing, a correct circuit pattern can be formed.

Title: Paper sheet separating device
Inventor: FUKUTOME YOSHIO
IPC: B65H3/52
Filed: 1992-04-24
Abstract: PURPOSE:To prevent the generation of wrinkles and damage specially at the time of delivering paper sheets of large size by specifying the radial dimension of guide rollers, provided at both outer ends of a feed roller shaft, in relation to the contact phase between the sheet and the high friction coefficient parts of pickup rollers. CONSTITUTION:Paper sheets delivered in by pickup rollers 18 are positively separated sheet by sheet by feed rollers 20 and gate rollers 15. While the foremost sheet of a sheet group P is being delivered in the separated state by the high friction coefficient members 19 of the pickup rollers 18, the radial dimension of the guide rollers 21 is smaller than that of the feed rollers 20, and the free end part of the sheet group is left in the pushed-out state, so that carrier resistance is not generated. When the sheet is being delivered by the holding force of pinch rollers 22, 23 and carrier rollers 20b after being delivered by the high friction coefficient members 19, the radial dimension of the guide rollers 21 becomes equal to that of the feed rollers 20, and the pushed-out state of the free end part of the sheet group is corrected.

After the substrate is immersed in a water soluble photosensitive resin, the solvent is removed, and further UV light is irradiated to the same to photoset the photosensitive resin, whereby a composite semipermeable membrane is obtd. When 2,500ppm aq. NaCl soln. is permeated through such semipermeable membrane under 70kg/cm<2> operating pressure, the rate of permeation is 0.025cm<2>/cm<2>.hr. atm, and the rate of removal is 34.6%. This semipermeable membrane requires the smaller amt. of the heat energy to be used in the stage of filming, thus economizing energy.

Title: Method for measuring acoustic velocity in steel plate in on-line
Inventor: MARUYAMA HIDEO
IPC: G01N29/00
Filed: 1984-05-29
Abstract: PURPOSE:To measure the acoustic velocity with a high accuracy by arranging a pair of ultrasonic transducers, which transmit sounds through water currents, on and under a steel plate. CONSTITUTION:Electric pulses generated by transmitters 5 and 5' are transduced to ultrasonic pulses by transducers 2 and 2' and are transmitted through water currents 4 and 4' and are reflected on surfaces of a steel plate 1 and are returned to transducers 2 and 2' again and pass switches 11 and 11' and are amplified by receiving amplifiers 6 and 6'. Gates 7 and 7' take out only transmission pulses and the first reflected pulses, and differential times tau1 and tau2 between these pulses are measured by time counting circuits 8 and 8'. Meanwhile, the upper transducer 2 and the lower transducer 2' are operated as the transmission side and the reception side respectively, and a gate circuit 7'' is used to measure a time tau0, when the pulses passes the olate, by a time counting circuit 8''.

Title: Dry evaporator
Inventor: MASUDA KIYOSHI
IPC: F28D7/16
Filed: 1991-05-13
Abstract: PURPOSE:To make a dry evaporator using a costly inner-finned device available at low cost relative to its costly use by employing an inexpensive smooth tube for a part of the channel for refrigerant without lowering the heat-exchanging efficiency. CONSTITUTION:A channel for refrigerant is formed of a smooth tube 5 and an inner- finned tube 6: said smooth tube 5, whose inner surface is smooth, is used for the part from the inlet into a shell 1 to the region where a ring-shaped flow of refrigerant, that is, a flow in contact with the inner surface of the tube, comes to an end; said inner-finned tube 6, which is provided with inner fins 62 inside, is used for the part from where the ring-shaped flow ends to the outlet of the channel. For the exchange of heat with liquid to be cooled, the refrigerant is passed through an inexpensive smooth tube 5 for the part of the channel from the inlet to the end of the ring-shaped flow, since in this particular region the difference in heat-transfer rate on the side of the refrigerant between the inner-finned tube 6 and the smooth tube 5 is small. For the exchange of heat in the region from where the ring-shaped flow ends to the outlet, use is made of the inner-finned tube 6 whose area effective for the exchange of heat per unit length is large so that the good heat-transfer rate of the inner-finned tube 6 on the side of refrigerant can be put to efficient use.

Title: Reproducing device of pcm signal
Inventor: FUKAMI TADASHI
IPC: H03M13/00
Filed: 1982-06-23
Abstract: PURPOSE:To absorb the lag of a reproducing period which is due to jitter, by making reproducing window pulse width slightly wider than a tape winding angle period. CONSTITUTION:Reproducing window pulses PBW from an ROM 12 are applied to AND gates 50, 51, etc. and reproducing PCM signals are written in RAMs 101, 102 for odd and even fields, respectively. The width of the pulses PBW is slightly longer than the period that a tape is wound around a guide drum and reproduced by a rotary head. During the period that the window is closed, a reproducing PCM signal is corrected at its error by parity check. Since the window is slightly longer than the reproducing period, the reproducing lag due to jitter or the like is absorbed during the window period and the PCM signal can be reproduced without a trouble also at the generation of the jitter or the like.
