Title: Treatment of microporous cellulosic film
Inventor: KURISAKA OSAMU
IPC: C08J9/36
Filed: 1982-02-16
Abstract: PURPOSE:To render a microporous cellulosic film hydrophilic without affecting the nature of its pores, by subjecting the microporous film of a cellulose derivative to a plasma treatment by high-frequency excitation. CONSTITUTION:A microporous film prepared from a cellulose derivative such as cellulose nitrate or cellulose acetate is subjected to a plasma treatment by high- frequency excitation. The plasma which can be applicable is a low-temperature plasma belonging to non-equilibrium plasma, which has an advantage of having little thermal influence on the film to be treated. Although there are several discharge systems such as an internal-electrode system, an external-electrode system, etc., the external-electrode system is preferred. As the gas, an inorganic gas, especially an inert gas such as argon, helium or nitrogen is used. The advantage of the plasma treatment is that the effect of modification extends only to a surfacial layer of a depth of several tens-several thousands Angstrom and, therefore, the essential characteristics of the film are not changed.

Abstract: PURPOSE:To shorten the extending length of a condensing part while maintaining the regenerating efficiency enough thereby to make the apparatus compact by making the width of a second regenerating part (condensing part) in a direction perpendicular to a longitudinal direction of a temperature adjusting member along a recording head larger than that of a first regenerating part. CONSTITUTION:In a condensing part 30 having an extension of a heat pipe 6 of a recording head 1 and cooled by a cooling fan 11, there are provided a plurality of cooling fins 7 along a direction of the air flow from the fan 11. The width L3 of the heat pipe 6 of the condensing part 30 is made larger than the width L2 where the heat pipe 6 is in touch with the recording head 1 to receive and transmit the heat, and the length L1A in a longitudinal direction of the heat pipe 6 at the condensing part 30 is set smaller. The width L2 is preferably 1.3 to 5 times the width L3 from the viewpoint of the improvement of the regenerating characteristics. The length L1A of the condensing part is also influenced by the relation between L2 and L3.

Title: Control device for electromagnetically proportional control valve
Inventor: OWADA MASAJI
IPC: F16D48/06
Filed: 1988-02-02
Abstract: PURPOSE:To enlarge the service temperature range by varying the oscillating frequency of the control current on the basis of the detection information by a temp. sensing means to sense the temp. of a working oil. CONSTITUTION:A temp. sensor 17 senses the temp. of a working oil in a decompressing valve 11, and the temp. of the working oil as detection information is fed into a control circuit 16. A No.2 control part 19 of this control circuit 16 varies the oscillating frequency of the control current on the basis of detection information by the temp. sensor 17, and the frequency of a dither to be applied to a spool 1 is optimally controlled according to the working oil temp. of the decompression valve 11. Therefore, dither of the decompression valve 11 as valve element is easily promoted even in the low temp. range. This decreases the friction resistance of the valve element in a wide temp. range, to lead to enhancement of the pressure accuracy of control oil pressure.

Title: Multi-stage low-frequency moving type heating and hardening device and method for using said device
Inventor: TSUCHIYA KATSUHIRO
IPC: C21D1/62
Filed: 1988-02-04
Abstract: PURPOSE:To prevent the temp. drop of a work at the time when said work passes between plural pieces of induction-heating coils and to adequately control the temp. distribution thereof by disposing said coils which generate the low frequency of the same frequency and can be discretely controlled in output to the device of a moving type hardening method. CONSTITUTION:A heating zone is formed by stacking, for example, the 1st - 3rd induction-heating coils 1a-1c concentrically, perpendicularly and substantially closely to multiple stages. The coils 1a-1c are connected respectively via variable matching transformers 2a-2c to one low-frequency output generation control device so that the current of the completely synchronized frequency is impressed to the coils. There is, therefore, no need for providing intervals between the coils in order to avert the relative interferences of the different frequencies. The individual coils 1a-1c can be discretely operated on and off by the transformers 2a-2c and further, arbitrary output levels can be applied by previously regulating the transformer taps 2a'-2c' and the control of the temp. to desired temp. distribution is thus enabled.
