Title: Vortex flowmeter
Inventor: WADA SHIYUNICHI
IPC: G01F1/32
Filed: 1983-01-26
Abstract: PURPOSE:To enable simultaneous measurement of volumetric flow rate and mass flow rate from the detection of the control signals for a vortex frequency and heat-sensitive elements by making combination use of the heat-sensitive element detecting the vortex and the heat-sensitive element detecting an average flow rate. CONSTITUTION:A flowmeter is constituted of a vortex generating body 3, hot wires 4 and 5, a support 6 for said wires and a measuring circuit 7, in a conduit 2. The hot wire 5 for detecting mainly the component of a change in flow rate owing to a vortex and the hot wire 4 for detecting mainly an average flow rate are provided. The frequency signal V4 of a Karman vortex and the analog output V5 of a hot wire flowmeter can be simultaneously and stabely detected with high accuracy for a long time by detecting the vortex signal and the vortex frequency from the differential signal of said wires. A change in flow except the Karman vortex, for example, an average flow rate and the abrupt change thereof, a change in the temp. of a fluid to be measured, etc. are negated as an in- phase component and therefore the exact measurement of the definite liquid in a wider flow rate range and with a larger change in the flow rate and temp. is made possible.

Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a double chuck propelling pencil with a tip chuck having a sufficient lead retaining force. SOLUTION: The tip chuck 30 has a head part 30a for retaining a lead and a barrel part 30b extending to the rear part from the head part 30a.

Title: Image processor
Inventor: TANABE RITSUJI
IPC: G06T11/00
Filed: 1992-01-28
Abstract: PURPOSE:To reduce memory capacity by storing gradation data for each color analyzing a command while coding the data into a little bits, making the number of planes in an image memory correspond to the number of bits in a gradation code, and decreasing the number of gradations by quantizing an image when it is judged for the image that the number of gradations is many. CONSTITUTION:When the same data are not existent in a gradation degree memory 103, a CPU 105 writes the gradation data in the gradation degree memory 103 and when the gradation data are registered on the gradation memory 103, the gradation data in an image processing instruction are replaced. This memory 103 is provided for gradation data to be handled by the image processing instruction, the data length is equal to that of gradation data to be switched, and the address length is shorter than the data length. This is because the CPU 105 can write the result in an image memory 104 with the address of the memory 103 so as to write it with quantity less than the information quantity of gradation data. Namely, the image processing instruction is reloaded by the scan processing of the CPU 105. Therefore, the image memory capacity can be reduced.

Next the resist mask 29 is provided and the ion implanted layers 30 are formed. The mask 29 is removed, the polysilicon film is oxidized to change itself to the oxide film 31, the layer 30 is activated to form the layers 32 -2 ∼32 -4  and the diffusion layer 33 that is from polysilicon. The n layers 32 -3 , 32 -4  of the transistor TR 2  are not overlapped on the gate electrode 26 -3  and are always "off", the gate electrode 26 -1  of the transistor TR 1  is overlapped on the n layers 32 -1 , 32 -2 . Next the surface is covered with oxide film 34 and selectively opened to remove the nitride film 27, the Al wiring 36 is formed. In this way, since the diffusion layer capacitance and gate capacitance decrease sharply in the "off " set transistor TR 2 , a high speed operation can be realized, the withstanding voltage is not dropped by ion implantation for controlling the threshold voltage.

When focus is displayed, shutter is released and a quick return mirror 3 kicks up. In cooperation with the movement of the mirror 3, an element holding plate 4 also kicks up and evacuates from the photographing optical path. A cushion member 10 serving also as a light shield is secured to the mirror 3, and the element holding plate 4 shields the reverse incident light from the finder by making close contact with the mirror 3. This constitution enables the time lag from release up to shutter to be reduced.
