IPC: B01L3/00
Filed: 1994-09-17
Abstract: PURPOSE: To analyze clinical liquid and/or suspension to clearly relate it to a clinically related class by evaluating an infrared spectrum generated from a dried sample using the multivariate evaluation method to allocate the sample to a class. CONSTITUTION: A dried sample 1 is placed in a recessed part of a carrier 2 made of gold-plated brass plate, and infrared rays(IR) from a radiation source 3 is radiated to the sample 1 through a hole of a concave mirror 4. The IR diffused and reflected on the sample is collected to the concave mirror 4 to be focussed to a detector 5, and then stored in RAM after the A/D conversion. The infrared spectrum generated at CPU is evaluated by the discrimination- analysis method(DA), and the evaluation results are displayed on a screen, a plotter, etc. In this case, in order to perform calibration, a sample of a known class is measured to determine a calibration parameter. Next, a sample of an unknown class is measured to determine a parameter. The classes can be clearly related to the samples, depending on whether a calibration matrix exists between the two parameters or not.

Abstract: PURPOSE:To constitute the title method so that neither adjustment of a gate part is performed nor flashes are generated on a cavity where filling quantity is a little, by a method wherein an opening and closing device of a gate is provided on the gate of the cavity where the filling quantity is a little. CONSTITUTION:At the time of filling of a materials 10, a gate 6 of a cavity 4 where the filling is a little is kept closed by an opening and closing device 11 of the gate and a screw 9 is moved forward so as to fill the material 10 into both the cavity 3, 4. The material 10 is filled into the cavity 3 where the filling is much from a gate 5 through a hot runner 7. When a screw 9 is moved forward up to a position A within an injection stroke S fixed beforehand, the same position is detected by a screw position detector, a solenoid directional control valve 113 becomes a position B by the same detected signal, the gate 6 is opened and the material is filled into also the cavity 4 where the filling is a little. The position A is in such a position that a predetermined remaining quantity to be filled into the cavity 3 where the filling is much and the quantity of the material to be filled into the cavity 4 where the filling is a little are almost the same with each other. Since the cavities where the filling are much and a little are filled with the material under a well-balanced state defective goods due to generation of flashes do not come out among molded products with the cavity where the filling is a little.

Title: Method for measuring particle size distribution by laser diffraction
Inventor: TOKAWA YOSHIAKI
IPC: G01N15/14
Filed: 1993-09-11
Abstract: PURPOSE:To automatically determine whether or not sample fine particles are being supplied so as to reduce the amount of consumption of the fine particles to the required minimum so as to enable a particle size distribution to be measured at low cost by measuring an increase in intensity of a scattered beam or decrease in quantity of a transmitted beam, which are caused by the sample fine particles supplied into a flow cell. CONSTITUTION:Sample fine particles S in a hopper 1 are introduced into a flow cell 2 and irradiated with a laser beam from a beam source 7, and the beam is scattered by the fine particles S, and the intensity of the beam transmitted decreases as the intensity of the scattered beam increases, and transmittance is lowered. When the supply of the fine particles S is stopped, the scattered beam intensity decreases while the transmittance increases. When the rate of increase in quantity of the scattered beam or the rate of lowering of the transmittance exceeds respective predetermined values, a CPU 15 determines that the fine particles S are being supplied, and takes measurements 10,12 of the scattered beam intensity and stores the measurement data. When the rate of decrease in quantity of the scattered beam or the rate of increase in quantity of the transmitted beam exceeds respective predetermined values, the CPU 15 determines that the fine particles S are no more being supplied, and terminates the storing of data about the scattered beam intensity and calculates a particle size distribution based on the data stored about the scattered beam intensity.

Title: Refrigerator
Inventor: NAGAE KOJI
IPC: F25B1/00
Filed: 1988-10-04
Abstract: PURPOSE:To make it possible to carry out efficient operation which meets cooling and heating loads by operating a bypass valve and controlling the output of both compressors when a single operation of a capacity variable type compressor shifts to simultaneous operation with a fixed capacity type compressor. CONSTITUTION:A fixed capacity type compressor 2a is operated by the rated 5 hp while a capacity variable type compressor 2b is operated by the maximum 5 hp respectively. When the capacity variable type compressor alone is operated only for a single room service and further when the operation switches over to a two room service and an entire room service, a bypass valve 19 is kept open by a control signal transmitted from a control means 21 until the horse power required by an indoor unit has reached 7 hp so that a part of refrigerant discharged from the compressor 2b is introduced to a low pressure side by way of a bypass passage 18, thereby lowering the output of the 5 hp compressor to 3 hp and reducing the capacity of the compressor 2b to 2 hp as well. When this is over, an attempt must be made to increase the capacity of the compressor 2b gradually, then close the bypass valve 19, and lower the capacity of the compressor 2b to 2 hp again. After this is over, the capacity of the compressor 2b must be gradually increased again. Therefore, this construction makes it possible to prevent a drastic change in the total output of the two compressors.
