Abstract: PURPOSE:To obtain a printed matter having high quality by pressing a lateral suitable position of one surface of a web stock to be fed toward a printer, forming a waviness substantially parallel to a longitudinal direction of the stock and eliminating a deviation of a previously printed image from a following printed image. CONSTITUTION:A web stock W to be fed by an operation of a rotary press is printed with a preceding image by a preceding printer P, and applied with dampening water from a nonimage part of a plate surface, The stock W is fed to next printer P' while the stock W given with the water is increasing in a lateral direction. It is passed through a web width regulator 20 on the way to form a waviness WA by pressing of a pressing mechanism 1, and a distance between both sides of the stock is shortened by L1, L2. than a lateral size of the actual stock W. It approaches to a size of the actual stock W while reaching the next printer P', and a printing pressure is applied in a state that the stock shortened by a size corresponding to cancel of laterally enlarged part with the dampening water before approaching, and printed in a state that next image is aligned with preceding image.

Title: Magnetic recording and reproducing device
Inventor: YAMAZAKI SHOHEI
IPC: G11B15/467
Filed: 1986-12-27
Abstract: PURPOSE:To stabilize tracking to an optimum state and to read a data with minimum level of missing, by transmitting an obtained tracking error signal to a tracking control system with a transfer gain being almost inversely proportional to a time interval, in a case that times when the tracking error signals are obtained are not arranged with equal intervals on a time base. CONSTITUTION:A reproducing signal sent to a control path 128 is inputted to an (Automatic Track Finding) ATF sync detection circuit 160, and sync signals f2 and f3 in an ATF signal are detected. A pilot level detection circuit 166 detects a tracking error at a tracking error detection circuit 168 by a timing signal generated from a timing generation circuit 170 based on the signals f2 and f3. An ATF1/ATF2 discrimination circuit 176 discriminates whether a detected ATF signal is an ATF1 or an ATF2, and performs the switching of a gain. In other words, the gain is increased in the ATF1 and is decreased in the ATF2, and its ratio is inversely proportioned to the time interval where an error signal is operated. In such a way, it is possible to apply the tracking, and to read the data with the minimum missing.

Title: Fabric for anti-heat sheet
Inventor: TANAKA JUN
IPC: B60N3/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To block permeation of the sun beam and conduction of the sun heat so as to improve the anti-heat property by providing a reflecting layer for reflecting the sun beam outside a cloth layer having the heat reserving property. SOLUTION: The fabric of an anti-heat sheet has a reflecting layer 2 for reflecting the sun beam provided outside a cloth layer 2. The cloth layer 1 is made of a polyethylene fiber cloth colored in black. The cloth layer 1 and the reflecting layer 2 are integrally bonded with an adhesive layer 3. According to the configuration, the sun beam can be reflected by the reflecting layer 2 so as to barely permeate inside the reflecting layer 2. Further, the sun heat conducted from the reflecting layer 2 is reserved (accumulated) in the black- colored cloth layer 1, and further, discharged from the reflecting layer 2 having a larger heat conductivity. Therefore, both sun beam and sun heat can be blocked inside the sheet and thus an excellent anti-heat property can be achieved.  Herein, by coloring the adhesive layer 3 in black, the heat reserving property can be provided in the adhesive layer 3 so that the anti-heat property can be further improved.

Title: Valve opening detecting method
Inventor: ADACHI TORU
IPC: F16K37/00
Filed: 1988-12-08
Abstract: PURPOSE:To detect the opening of a valve body based on the difference between received wave-forms by transmitting an ultrasonic pulse twice to a valve rod at a slight stagger. CONSTITUTION:An ultrasonic pulse signal is transmitted from a transceiver 21 to the cap 8 of a valve rod. The ultrasonic wave is reflected by an insertion side end face 13 and a hollow hole bottom face 10 and returned to the cap 8, and it is received by the transceiver 21 and sent to an ultrasonic receiving circuit 23. Various reflected wave-forms are mixed in the reflected wave from the hollow hole bottom face 10, thus discrimination may be sometimes impos sible. The received wave-form of the receiving circuit 23 is digitized, then the opening H of the valve body 6 is slightly changed, and an ultrasonic wave is again transmitted and received and digitized. Only the opening H is changed on these wave-forms, the difference between both wave-forms is detected by a valve body reflection detecting circuit 26 to discriminate the valve body reflected wave, it is compared and calculated with the reflected wave from the valve rod insertion side end face 13, and the opening H is found and dis played. The opening of the valve body can be thereby detected.

Title: Electronic component
Inventor: HIRANO MASAO
IPC: H05K3/34
Filed: 1990-11-15
Abstract: PURPOSE:To enhance a heat efficiency at the bonding operation of a lead and to prevent the dislocation and the thermal deterioration of an electronic component by a method wherein the whole region or at least a partial region other than a bonding region which is bonded to other electronic circuit elements on the surface of the lead is covered with a material whose heat radiation coefficient is high. CONSTITUTION:The whole region or at least a partial region other than a bonding region 4a on the surface of a lead 4 is covered with a high-heat- radiation-coefficient layer 5. Thereby, the bonding region 4a of the lead 4 is brought into contact with other electronic circuit elements such as an interconnection pad 7 and the like. When the high-heat-radiation-coefficient layer 5 is irradiated with a laser beam alpha, the laser beam alpha is absorbed efficiently, and the lead 4 can be bonded to the other electronic circuit elements in a short time. Since the lead 4 is covered with the high-heat-radiation-coefficient layer 5, heat is dissipated well immediately after a bonding operation, and the cooling speed of the lead 4 is large. Thereby, a heat efficiency can be enhanced at the bonding operation of the lead, and it is possible to prevent the dislocation and the thermal deterioration of an electronic component.
