Abstract: A method of treating positive photoresist materials applied on a semiconductor wafer (5) placed on a support (6), which meets the demand for high-speed treatment and improvement in heat-resistance and etching-­resistance of the developed positive photoresist image (4). The semiconductor wafer (5) is heated by being exposed to radiant lights from a lamp (1) such as a high pressure mer­cury vapor lamp radiating lights containing wavelengths of 350nm or below in a chamber (7) filled with gas of lower pressure than 1 atmospheric pressure. While the semiconductor wafer is placed on the support, the speed to raise the temperature of the semiconductor wafer is controlled by exchanging the support for another with the different thickness.

Abstract: Mouldable textile sheet-like structure for lining noise-polluted spaces, in particular the passenger space of motor vehicles, consisting of a fabric, a needle-punched or tufted layer as a visible surface, in each case at least one thermoplastically mouldable and back-sprayable layer and one foamed backing layer, in which the layer serving as a visible layer consists of needle felt or a tufting surface (2) needle-punched into felt as a substrate layer (1), on the back of which a layer (3) of foamed latex, furthermore a dense barrier layer (4) and furthermore, if required, the foamed backing layer (5) are applied. It is also possible to provide, as a substrate layer, a thin layer of a readily consolidated felt, which is laminated with a thicker layer of an unconsolidated felt by means of a binder simultaneously serving to bind the needle-punched material in the substrate layer. The layers possess a sound transmittance which decreases continuously from the substrate layer (1) to the backing layer (5). The barrier layer (4) is formed by a sheet or a coating of unfoamed latex.

Abstract: A grip shaft (2) is supported on a cylinder that makes a reciprocating rotational motion. The grip shaft (2) is provided with a grip (3) for holding a printing material. The grip (3) is further provided with a cam follower (6). A cam (21) is positioned along the path of motion of the cam follower, and the cam follower engages with an opening portion (22) of the cam when the grip is right before a printing material feeder portion, and opens the grip. Further, when the grip reaches the printing material feeder portion, the cam follower moves to a closing portion (23) of the cam, closing the grip to hold a printing material. After the grip has held a printing material, the cam follower disengages from the cam as the cylinder is rotated in the opposite direction. The opening portion and the closing portion composes a continuous cam surface.

Abstract: A tag has a memory programmable to store alphanumeric indications in a pattern identifying an object associated with the tag. The stored indications are convertible to signals transmitted to a displaced reader in an individual pattern at first and second frequencies to identify the object. The memory may be programmed, during the production of a first logic level in a signal on a program pin, (a) by the operation of keys on a keyboard in a programmer housing, each key representing an individual alphanumeric character, or (b) from an external source such as a typewriter keyboard used in conjunction with the programmer. The signal on the program pin has a second logic level to provide for bulk erasing all particular memory positions. A configuration signal has a first logic level providing for the alphanumeric coding of the memory and a second logic level providing for the selection, at particular memory positions, of individual capacitors to generate signals at the first and second frequencies. When the programming signal has the second logic level and the configuration signal has the first logic level, bulk information may be erased from the memory. Dependent upon the logic levels of the programming and configuration signals, (1) information is programmed in the memory, (2) the capacitors are selected or (3) programmed information is bulk erased when an energizing pin in the programmer receives a particular voltage. A detent on the tag has a plurality of pads for introducing the different logic levels to the programming configuration and energizing pads in   the tag. This detent mates with a detent in the programmer housing to provide for the introduction of the programming, configuration and energizing signals to the tag through the pads in the tag detent.

A selecting means (32) outputs a first signal representing a predetermined value and outputs a second signal representing a value greater than the first signal in accordance with said selected mode signal. A comparing means (33) is responsive to the selecting means for comparing the maximum value of the induction signals with the signal outputted by the selecting means. Calculating means (34) responds to the comparing means (33) for calculating co-ordinate values from the induction signals.

Abstract: Aluminium-containing alloys are protected against high temperature corrosive attack by providing an amorphous silica coating, e.g. by plasma assisted vapour deposition, followed by heat treating under conditions such that a coherent, protective alumina coating or layer is formed on the surface of the alloy in place of the silica coating. The silica protects the alloy from corrosion initially and then acts as an oxidant source so that aluminium from the alloy can react to form the alumina coating. The alloy may be a superalloy such as a nickel-base superalloy.

Abstract: A tape synchronising apparatus for a tape reproducer using a tape with information signals and time code signals recorded thereon and serving to reproduce such signals from the tape. When attaining synchronism with a reference time code before return of a rewound tape to a target in-point, there is calculated, at the instant of the tape speed rise to a predetermined constant speed, the difference between the respective remaining times of both the read and reference time codes until the target in-point, and the preset value of the reference time code at the tape rewind instant is further offset by the difference from the time period corresponding to the tape rewind, so that the difference is reduced substantially to zero at the next tape speed rise, thereby shortening the time required for synchronisation (phase modification).

Abstract: Continuous core samples are obtained from along the length of a wellbore. Discrete samples are obtained from the continuous core samples at selected intervals so as to be representative of the formation lithologies transversed by the wellbore along its length. The samples can then be processed at the wellsite with a transportable laboratory so as to obtain measures of a plurality of selected physical properties of the subterranean formations representative of their in-situ condition. An inverse log of each physical property as a function of depth can be prepared with which explorationists can evaluate geophysical survey data for oil and gas potential. Additionally, inverse logs of one or more of the physical properties can be used to perform basis analyses. When used for basis analysis, the physical properties of each inverse log can be used to calibrate geophysical survey data of the basin at one or more wellbore sites within the basin from which the inverse logs were obtained.
