Patent EP-0088594-A2 (EP)
Inventor: COLES ROBERT F
IPC: G03C1/36
Filed: 1983-03-03
Abstract: This invention relates to isoindoline derivatives and to a process for preparing these derivatives. 
     The isoindoline derivatives of this invention are cationic dyes suitable for modifying the sensitivity of silver halide emulsions. White light handleable photographic film is subject to fogging by low intensity light. By incorporating these isoindoline cationic dyes into suitable silver halide emusions, the emulsions will not be fogged by low intensity light even after many hours of exposure. However, these emulsions may still be exposed by exposing radiation of higher intensity than normal room light. The isoindoline derivatives are monosubstituted in the 1-position, and correspond to the general formula:
     In which the cyclic radical R is an aromatic ring, a substituted aromatic ring a tetrahydregenated aromatic ring. a nitrogen containing heterocyclic ring. or a sulfur-containing hetero cyclic ring, and R 1  is a substituent represented by the general formula
     where Y is an atom of oxygen, nitrogen, sulfur, or carbon, Z is the atom or atoms necessary to form a 5-membered or 6- membered carbocyclic or heterocyclic ring which may have a fused-on aromatic ring selected from phenyl and naphthyl groups, R 2  is an alkyl, sulfoalkyl, or carboxyalkyl radical, and X -  is the anion for the cationic quaternary nitrogen.

Abstract: An integrated circuit device comprises a data processing unit (CPU) (1), a first read only memory (ROM) (5) storing an applications program to be executed in the CPU, a second ROM (6) having an address space which is addressed in common with the first ROM and storing a test program for a function diagnosis, and a test control unit (14). The test control unit is responsive to a test control signal (TEST) externally applied in a test mode to couple the second ROM to the CPU so that the test program for setting an initial condition is executed. During the execution of the test program, the first ROM is coupled to the CPU, thereby executing applications program instructions the contents and the number of which are externally designated. Thereafter, the second ROM is coupled to the CPU so as to execute the test program for deciding a test complete condition. The execution result of the applications program instructions are compared with expected values to decide if the integrated circuit device functions normally. The address space of first and second ROMs is expanded in a software manner, and the address space of the first ROM can be assigned only to the applications program.

Abstract: @ A molecular beam epitaxy system wherein the wafer (26) on which epitaxial deposition is to occur is not soldered to a substrate holder. Instead, a substrate holder (102) with a lip (114) approximately as high as the thickness of the wafer (26) is used, and a retaining ring (112) attaches to the substrate holder to hold the wafer in place during the growth cycle. The retaining ring (112), like the substrate holder (102), is made of high-purity refractory material, such as arccast molybdenum. The substrate holder (102) and retaining ring (112) are dimensioned to hold the wafer (26) somewhat loosely, to allow for thermal expansion during the cycling up to growth temperature, which is typically about 600 degrees C. The system also may include a growth chamber heater for bakeout, a source outgassing mount in an analysis chamber, and a mounting system for inserting a wafer from a cassette of wafers into the substrate holder.

Abstract: A load sensor (11c) includes a fixed rigid portion (13c), a movable rigid portion (14c) spaced from the fixed rigid portion and adapted to receive an applied load, and a shear-deformable member (30) provided between the two rigid portions. The shear-deformable portion is provided with transmission and reception transducers (34, 35) constituting an elastic surface-wave oscillator. When a load is applied to the movable rigid portion, weight is sensed based on a deviation in the oscillation frequency of the elastic surface-wave oscillator. The fixed and movable rigid portions, as well as upper and lower beams interconnecting these portions, constitute a load-sensitive element (12c). The latter has a side face (121c) which is closed off by a pliable membrane (36) for sealing the shear-deformable element disposed within the load-sensitive element. Alternatively, a corrugated bellows is connected across the fixed and movable rigid portions to seal the shear-deformable member within the bellows. In this way the surface-wave resonator can be desirably protected from the environment.
