Title: Pump of constant discharge pressure
Inventor: KOBAYASHI KAZUNARI
IPC: F04D15/00
Filed: 1979-05-31
Abstract: PURPOSE: To keep the discharge pressure of a pump constant, by securing a piston on one end of a main shaft whereon impellers are fixed, applying pressure equal to the discharge pressure to one face of the piston and applying pressure equal to a desired discharge level to the other face of the piston.  
     CONSTITUTION: The main shaft 1 whereon the imellers 5, 6 are fixed are supported so that main shaft cah slide rightward from such a state that the distance (a) between the blades 11, 12 of the impellers 5, 6 is minimum. The piston 9 is secured on one end of the main shaft 1. The pressure equal to the discharge pressure is applied to one chamber 39 of a cylinder 8 through a diaphragm 122. The pressure equalized to the desired discharge level by a constant pressure valve 51 is applied to another chamber 40 of the cylinder 8 through a diaphragm 123. When the discharge pressure rises, the main shaft 1 moves rightward and the distance (a) increases to reduce the discharge pressure. When the discharge pressure falls, the main shaft 1 moves leftward and the distance (a) decreases to raise the discharge pressure. The discharge pressure is thus kept constant.

Abstract: PURPOSE:To measure temperature with high sensitivity by projecting and photodetecting light from a light source on an interference film filter as a temperature sensing part through an optical fiber, diffracting light from the optical fiber spectrally and detecting it by a detector, and measuring the temperature from their outputs. CONSTITUTION:The light from the light source 1 such as an incandescent lamp is projected on the multilayered interference film filter 3 as the temperature sensing part by the optical fiber 21 and light transmitted through the filter 3 is guided out through an optical fiber 22. The light from the fiber 22 is diffracted spectrally by a spectral diffracting means 4 such as a prism and detected by a detector 5, and a measuring means 6 measures the temperature from the output of the detector 5. Namely, the filter 3 shifts in transmission wavelength characteristics to the long- wavelength side from A to A' as the temperature T rises. Specific wavelength B of the light which is diffracted spectrally by the spectral diffracting means 4 and detected by the detector 5, on the other hand, is constant, so the degree (product) of the overlap between A or A' and B varies with the temperature T and radiant energy incident on the detector 5 varies. Then the measuring means 6 measures the temperature T from the output of the detector 5 by an arithmetic expression found by an experiment, etc.

Title: Control circuit of center tap output selection for floppy disk drive
Inventor: FUKUYAMA MAKOTO
IPC: G11B19/00
Filed: 1984-04-05
Abstract: PURPOSE:To protect data even when malfunctions occur during write and erase operations in case mode signals for starting write and erase operations are impressed, by holding the center tap selection output at the moment when shifting to the modes. CONSTITUTION:At the time of the reproducing mode, ''H'' is impressed upon terminals 1 and 2 and ''L'' is impressed upon one side inputs of NANDs 10 and 11. Since the other inputs of the NANDs 10 and 11 are always ''H'', the outputs of the NANDs 10 and 11 becomes ''H'' and the output of a NAND12 becomes ''L'' and that of an inverter 13 becomes ''H''. This signal is impressed upon one side inputs of NANDs 15 and 16. When an input terminal 3 is set to ''H'' under this condition, the output of an inverter 9 becomes ''L'' and that of another inverter 14 becomes ''H''. The output of the NAND15 becomes ''H'' and that of the NAND16 becomes ''L'' and, as a result, ''L'' is obtained at a control output terminal 19 as a select signal by an RSFF50. When the mode signal to the terminal 1 is shifted from ''H'' ot ''L'' (erasing mode) under a condition where the input terminal 3 is ''H'', ''L'' is held and outputted as a select signal. By holding the selection output at the moment when the mode is shifted to a selected mode, data in a disk can be protected.

Title: Specimen coating device
Inventor: HIJIKATA KAZUO
IPC: G01N27/447
Filed: 1979-06-05
Abstract: PURPOSE: To eliminate the uneven coating and thus obtain the accurate data, by identifying the wetting state through measurement of the reflected light of the supporter and then carrying out the coating of the specimen in the optimum state.  
     CONSTITUTION: The reflected light volume on the surface of supporter 11 is received continuously via photoelectric conversion element 16, and the output proportional to the reflected light volume is sent to amplifier/comparator circuit 18. At circuit 18 the output of element 16 is compared with the reference level at all times, and the output is delivered when the coincidence is obtained through the comparison. Thus control circuit 19 operates to actuate motor 20, and thus coating tip 12 is moved up and down to perform the specimen coating for supporter 11. In this case, the specimen is attached to tip 12 immediately before coating in order to secure the quick coating action. In this way, tip 12 can be prevented from being dried up. Thus the optimum wetting state can always be secured automatically to carry out the specimen coating although the speed may change for the aging of the wetting state caused by the change of the ambient humidity or the like of supporter 11.
