Title: Karman vortex flow meter
Inventor: YASUI KATSUAKI
IPC: G01F1/32
Filed: 1988-03-15
Abstract: PURPOSE:To measure flow rates over a wide range with high accuracy by providing a vortex street generating column, an ultrasonic wave generator for detecting the frequencies of the generated Karman vortex streets, an ultrasonic wave receiver and a heat generating means to a conduit in which fluid to be measured flows. CONSTITUTION:The flow flowed into the conduit 1 is regulated by a honeycomb 7. Since one side 7a of the honeycomb 7 is heated by a heater 6, only the part near the heater 6 is heated and a temp. difference arises in the right and left flows. The flows form the Karman vortex streets (c) behind stabilizing plates 3 by the effect of the plates 3. The Karman vortex streets having a cold part in the direction perpendicular to the flow direction A and perpendicular to the longitudinal direction B of the vortex flow generating column 2 and the Karman vortex streets having a warm part in said direction are, therefore, generated alternately behind the plates 3. Since the velocity of sound is higher in the warm part than in the cold part, the phase of the ultrasonic wave is advanced or delayed when the warm fluid or cold fluid flows much into the spacing between the ultrasonic wave generator 4 and the ultrasonic wave receiver 5. The velocity of flow, etc., of the fluid to be measured are determined by detecting such phase change.

Abstract: PURPOSE:To compensate the drop of the boosting level of a word line and to ensure the full writing to a memory capactor by adding a level compensating circuit which detects the drop of the word line selecting level and recovers the dropped level up to the level of the power supply voltage. CONSTITUTION:The level differences VH and VL appear at complelementary data lines DL and DL by a word line selection timing singnal phix. A sense amplifier SA is activated by a timing signal phipa1, and an FETQ8 is turned on by a timing signal phipa2. Then the data line of low level VL is quickly changed to a low level, and this low level is transmitted to the work line by coupling. Thus the boosting voltage of the signal phix is dropped. An FETQ11 of a level compensating circuit LV is turned off, and the gate voltage of an FETQ 10 is set at a high level to recover the level of the signal phix up to the power supply voltage Vcc. Then an active restoring circuit AR is actuated to recover the high level up to the Vcc and written again to a memory capacitor Cs through an address selecting MOSFETQm.

Title: Formation of simulated etching pattern
Inventor: FUKUMURA NORIO
IPC: C23F1/00
Filed: 1981-04-27
Abstract: PURPOSE: To form simulated etching patterns on an opaque base material having high specular gloss rate by forming micro-ruggedness on the surface of a printed pattern layer thereby making the specular gloss rate of vapor deposited metallic layer lower than that in the parts other than the pattern layers.  
     CONSTITUTION: Desired printed pattern layers 2 having micro-ruggendness are formed on an opaque base material 1 of high specular gloss, thence a vapor- deposited metallic layer 3 is formed. Since ruggedness is left on the layers 3a on the layers 2, the specular gloss rate is ≤ 50% and the other parts 3b has high metallic gloss of ≥70% specular gloss rate; therefore the parts of the layers 3 form simulated etching patterns although they are built up in actuality. Steel having smooth surface or the like is used for the base material. The ruggedness on the surface of the printed patterns is formed by means such as print meshes, matting agents, inclusion of foaming agents or the like. Al or the like is used for the vapor depositing metal.
