Title: Photosensitive resin material for letterpress used in hot stamping
Inventor: FUJIKAWA JUNICHI
IPC: G03F7/00
Filed: 1988-06-10
Abstract: PURPOSE:To facilitate formation of a letterpress and to reduce cost by regulating the hardness of a photosetting part to a specified value. CONSTITUTION:The hardness of a photosetting part of the title letterpress material is regulated to >=80 of a Barcol hardness tester GYZJ 936. If the hardness is <80, sufficient stamping is impossible due to deformation of a relief by a pressure in a stamping stage. The letterpress material is produced by forming a photosensitive layer consisting of a completely or partially saponified polyvinyl acetate, a photosetting compd.(e.g. glycerol dimethacrylate), and a photosensitizing agent(e.g. dimethyl benzyl ketal), etc., on a base plate. Further, the letterpress can be formed by adhering tightly a negative film having a desired pattern to said letterpress material, exposing the material to a specified amt. of ultraviolet rays, then developing the material.

Title: Thrust reduction device for screw compressor
Inventor: ISHII MASAHARU
IPC: F04C29/00
Filed: 1978-11-24
Abstract: PURPOSE: To obtain a differential pressure sufficiently large to reduce the thrust force with small amount of oil, by forming an oil relief passage in a casing between the oil supply side and the opposite side of a balance piston.  
     CONSTITUTION: An oil relief passage 21 and an oil relief groove 20 are formed in the portion of a casing 6 between the oil supply side and opposite side of a balance piston 14. As a high-pressure oil is introduced through an oil supplying port 17, the oil pressure acts on the right side of the balance piston and relieved into the low- pressure side through a gap around the balance piston 14. The oil residing in this gap is scattered radially outwardly by the centrifugal force generated by the rotation of the balance piston 14 and comes into the oil relieving groove 20. The oil is then returned to the low-pressure side of the compressor through the oil relieving port 21 and a part of the oil flows to the left side of the balance piston 14. In consequence, the amount of oil flowing out of the balance piston 14 is reduced to make it possible to obtain a differential pressure sufficiently large to reduce the thrust force, with a reduced amount of oil.

Abstract: PURPOSE:To obtain high wavelength conversion efficiency by adequately setting the polarization direction of the basic waves made incident on the PRA crystal expressed by specific molecular formula. CONSTITUTION:The single crystal of the nonlinear optical material 3, 5- dimethyl-1-(4-nitrophenyl) pyrazole: PRA expressed by formula I is used and the linearly polarized basic waves of the respective wavelengths existing between 450 and 4000nm are made incident on this bulk single crystal and the angle phase matching of a type I is attained, by which the sum frequency thereof is obtd. Namely, the phase matching conditions of the type I are nW<1>, 2/lambda1+nW<2>, 2/lambda2=nW<3>, 1/lambda3 when the refractive indices of the wavelengths lambda1, lambda2 when made incident at an arbitrary angle to respective basic waves are designated as nW<1>, nW<2> and the refractive indices of the wavelength lambda3 to the sum frequency is designated as nW<3>. The high conversion efficiency is obtd. if such conditions are satisfied. Since the PRA does not absorb much light near 400nm wavelength and, therefore, the sum frequency of the blue region is efficiently generated. The high wavelength conversion efficiency is obtd. in this way and the sum frequency of the blue region is easily obtd.

Title: Facsimile training signal transmitting system
Inventor: MORIYAMA YUTAKA
IPC: H04N1/32
Filed: 1991-06-17
Abstract: PURPOSE:To reduce the processing quantity of a transmitter, and to attain the sure transmission and reception of a facsimile training signal by detecting the changing point of the theoretical value of a bit contained in a digital signal, and sending its detected result to a digital circuit. CONSTITUTION:A changing point detecting means 11 detects the changing point of the theoretical value of each bit contained in a facsimile training signal, and sends information to show the changing point to the digital circuit through a detected result sending means 13. The normal facsimile training signal is constituted of the continuous bits of a definite theoretical value, and this changing point information is not sent unless the facsimile training signal is received by mistake. Namely, since the information of the facsimile training signal is compressed and sent, in the transmitter facing it through the digital circuit, the quantity of the information to be processed as following the transmission and reception of this signal is reduced, and the facsimile training signal can be easily regenerated by executing processing reverse to the changing point detecting means 11.

Filed: 1981-09-14
Abstract: PURPOSE:To warn the abnormality of the system, by distinguishing the abnormality of a main operation panel and the abnormality of a transmission line from each other to output respective corresponding sound output when the abnormality occurs. CONSTITUTION:If a main operation panel 1 or a transmission line 2 becomes abnormal, periodic pulses are not inputted to a retriggerrable monostable multivibrator 4, and therefore, a relay Ry6 is turned off, and a sound synthesizing part 5 is interrupted. When it is interrupted, a CPU in the sound synthesizing part 5 executes the interuption processing. That is, statuses of the strobe input and data inputs 1-4 are inputted. When the transmission line 2 is abnormal because of short-circuit or disconnection, a transistor TR Q7 other than TRs Q1-Q5 is turned on, and the electric charge of a capacitor C is discharged through relays Ry1-Ry5, and therefore, relays Ry1-Ry5 are turned on, and all of the strobe input and data inputs 1-4 become low. Meanwhile, when a voltage exists on the transmission line 2, strobe input and data inputs 1-4 become high because  relays Ry1-Ry5 are turned off. Consequently, the sound synthesizing part 5 distinguishes abnormalities of the main operation panel 1 and the transmission line 2 from each other and outputs respective corresponding sound outputs.

Abstract: PURPOSE:To surely control the load to the safety side by making use of the 1st output terminal which is set at L while a microcomputer is kept under a reset state after application of a power supply to inhibit the working of the load of a solenoid valve, etc. connected to other output terminals. CONSTITUTION:The 1st output terminal P1 is kept at L in a non-reset period and therefore a transistor TR1 is never turned on as long as the 2nd output terminal P2 is set so as to satisfy an inequality (1) regardless of the voltage level of the terminal P2.

Under such conditions, a solenoid valve is kept closed. When the solenoid valve is opened, the resistance value of a resistance 4 is set so as to satisfy an inequality (2) together with both terminals P1 and P2 kept at H levels respectively. Here VR is the terminal voltage of the resistance 4 and VBE5(ON) is the base-emitter voltage in case a TR5 is turned on.
