A heater comprises an insulating substrate which carries a parallel pair of conductor strips. The respective conductor strips are spaced from each other transversely thereof but electrically connected to each other by a plurality of heating resistors which are spaced longitudinally of the respective conductor strips. Advantageously, the heating resistors are arranged or configured so that the heater will have a temperature distribution which is equalized longitudinally.

A heater for a sheet material comprises an insulating substrate and a main resistor strip formed on the substrate. The substrate is further formed with auxiliary resistor strips adjacent to both ends of the main resistor strip. In operation, the main and auxiliary resistor strips are actuated simultaneously for heat generation. As a result, the additional heat generated by the auxiliary resistor strips compensates for higher heat dissipation at both ends of the heater, thereby equalizing the temperature distribution longitudinally of the heater.

A heater for heating a sheet material along a standard contact line comprises an insulating substrate, and a heating resistor strip formed on a surface of the substrate to extend longitudinally thereof. The resistor strip has an intermediate portion which is located transversely offset from the standard contact line, and a pair of end portions located at least partially at the standard contact line.

A pair of holes are formed with a predetermined space therebetween on a long and narrow base plate. An adhesive is applied to the surface of the base plate. Head substrates each having a row of thermal resistors on the surface thereof are placed on the adhesive on the base plate such that the joint of the head substrates is positioned between the pair of holes of the base plate. The adhesive is hardened in the state in which the head substrates are pushed upward by thrusting means inserted into a pair of holes while the base plate is supported from below and the head substrates is pressed from above. The base plate is bonded to a radiating plate by an adhesive only at the central portion. Thus, there is no difference in level at the joint of the head substrates, and even when the radiating plate expands due to heat, the base plate is not deformed.

A thermal printing head comprises a support member, a head circuit board supported on the support member, a connector board overlapped on the head circuit board, and a presser member for pressing the connector board against the head circuit board. The support member is flexible with a modulus of elasticity lying within a range of 1.times.10.sup.4 -5.times.10.sup.5 kg/mm.sup.2. The head circuit board carries a comb-like terminal portion arranged in a limited central portion which is substantially smaller in length than the head circuit board. The connector board also carries a comb-like terminal portion corresponding to the terminal portion of the head circuit board, and the length of the connector board is substantially smaller than that of the head circuit board.

A thermal print head comprises a head circuit board which is made of an insulating material, the heat circuit board carrying a heating resistor, a plurality of drive elements for heating the resistor, a plurality of connection terminals, and a wiring conductor pattern connecting the connection terminals to the drive elements. The wiring conductor pattern comprises a plurality of separate printed wirings, at least one of the wirings having at least one pair of separated ends which are connected by a raised wire, at least one of the other wirings being made to extend between the pair of separated ends.

A patch permitting division of only its release sheet by simply pulling right and left, wherein detachment of the release sheet is easy. There is provided a patch comprising a stretchable support, a plaster applied substantially all over one major surface of the support and a release sheet attached to the whole surface of the plaster wherein only the release sheet is divided at a division zone by simply pulling right and left, and wherein one or two or more precut parts that open when the patch is pulled right and left are disposed in the neighborhood on the division zone.

An outer ring member for a constant velocity joint is manufactured. An intermediate preformed product having a cup section with an incomplete shape is formed by pressing a large diameter section without applying a low temperature annealing treatment and a lubricating chemical conversion coating treatment. Then, applying a low temperature annealing treatment and a lubricating chemical conversion coating treatment to the intermediate preformed product, thereafter a formed product having a cup section provided with ball-rolling grooves is formed by backward extrusion to the intermediate preformed product. Subsequently, the product is ironed before hardening, without applying a low temperature annealing treatment and a lubricating chemical conversion coating treatment to the formed product.

A pair of holes are formed with a predetermined space therebetween on a long and narrow base plate. An adhesive is applied to the surface of the base plate. Head substrates each having a row of thermal resistors on the surface thereof are placed on the adhesive on the base plate such that the joint of the head substrates is positioned between the pair of holes of the base plate. The adhesive is hardened in the state in which the head substrates are pushed upward by a thruster(s) means inserted into a pair of holes while the base plate is supported from below and the head substrates is pressed from above. The base plate is bonded to a radiating plate by an adhesive only at the central portion. Thus, there is no difference in level at the joint of the head substrates, and even when the radiating plate expands due to heat, the base plate is not deformed.
摘要:
A linear heater comprises an insulating substrate, at least one resistor strip formed on the substrate, insulating edge members formed on the substrate to extend along the respective longitudinal margins of the resistor strip in contact therewith, and a heat-resistant protective coating formed on the substrate for covering the resistor strip and the respective edge members. The respective edge members, which themselves provide an insulating function, compensate for a thickness reduction of the protective coating at positions corresponding to the longitudinal margins of the resistor strip.
