Abstract: The data processing device has a battery, a memory, a detector and an message output. The memory stores data on electric power consumption or electric current. The detector detects electric power or electric current supplied from the battery. The message output indicates when the detected electric power or electric current supplied from the battery is greater than the data value read out from the memory.

Abstract: An electronic digital pressure switch for detecting gas pressures features improved safety. The digital pressure switch that detects gas pressures and generates outputs has a housing provided with pinholes that allow a gas to pass therethrough. With this arrangement, even if a gas should leak into the housing, the leakage gas is let out through the pinholes. Thus, when the pressure of a flammable gas is detected, it is possible to eliminate the danger of an explosion caused by the flammable gas accumulating in the housing.

Abstract: An alignment treating agent for a liquid crystal cell, which is composed mainly of a polyimide and/or a polyimide precursor made by a reaction for polymerization of a tetracarboxylic acid derivative component with a diamine component, wherein at least one part of the diamine component is a diamine component of the following formula (1): ##STR1## wherein n is an integer of from 1 to 12, and which gives a tilt angle of at most 2.degree. to nematic liquid crystal.

Abstract: A diaminobenzene derivative of the formula (I): ##STR1## wherein each of P and Q which may be the same or different from each other, is a single bond, or a bivalent organic group selected from the group consisting of --O--, --COO-- and --CONH--, R.sub.1 is a C.sub.2-22 straight chain alkylene group, and R.sub.2 is a cyclic group selected from the group consisting of an aromatic ring, an aliphatic ring, a heterocyclic ring and substituted forms of such rings.

Abstract: A circuit construction comprising a diode and a capacitor is connected to a secondary coil of a thin transformer such as a wire-type transformer. An excitation energy is discharged during a reset time of the transformer, and this excitation energy is accumulated in the capacitor, thereby output voltage is obtained through the capacitor. A direct current output voltages having two outputs is obtained through one transformer. A small volume and a light weight of the transformer, so that a compact and thin power supply apparatus can be obtained. Since a winding ratio of the transformer can be made small, a copper loss of the transformer can be reduced. It is unnecessary to select a higher switching frequency and a manufacturing cost of the power supply apparatus can be reduced.

Abstract: A treating method for aligning liquid crystal molecules, which comprises forming on a substrate a polyimide film represented by a repeating unit of the formula (I): ##STR1## wherein R is a bivalent organic group, irradiating the film with ultraviolet rays having a spatial distribution of irradiation intensity through a mask, immersing it in a developing liquid and then in a rinsing liquid to form periodical concaves and convexes on the surface of the polyimide film, and aligning liquid crystal molecules on the concave-convex surface.

Abstract: A liquid crystal alignment film made of a polyimide which has, on its side chain, a benzene or biphenyl ring substituted by a monovalent substituent having a positive value as the .sigma.p value under Hammett's rule.

Abstract: The concomitant administration of L-pyroglutamyl-L-histidyl-L-prolinamide or its physiologically acceptable salt with one or more neuroleptics to patients suffering from schizophrenia can attain remarkable improvement of the overall disease picture of the patients.

Abstract: A coaxial cable for radio frequency signal coupling comprises elongated, coaxial, central and external conductors. A continuous slot is provided in the external conductor in the form of a regularly alternately undulating or zig-zag pattern.
