By means of the recessed section 3, the silicon oxide film below the element 5 forms a cantilever 4 which is projected above the recessed section 3. When a weight or acceleration or both of them are applied to the cantilever 4 in the vertical direction, the cantilever 4 is bent in the vertical direction and, when receives bending distortion, the element 5 made of a metallic film produces changes in resistance value. When the changes in resistance value are calculated, the load or acceleration can be detected.

Title: Light emitting element array
Inventor: KUSUDA YUKIHISA
IPC: B41J2/44
Filed: 1990-09-19
Abstract: PURPOSE:To enable a light emitting element array to be remarkably enhanced in photosensitivity by a method wherein a controllable current is made to flow through a first control electrode from an outer terminal corresponding to optical data which are made to irradiate the light emitting element. CONSTITUTION:A voltage is supplied to a feed line 1 of a transfer clock phi1 and a light emitting thyristor T1 is irradiated with light. At this point, a photocurrent iP is made to flow through the light emitting thyristor T1. Then, when a control pulse phiP is made to decrease in voltage, instantaneously a displacement current iC is made to flow through a capacitor C1. The current iC enables a current iC1 to be extracted from a gate G1 of a T1. The current iC1 is smaller than the current iC, and a current obtained by subtracting iC1 from iC is correspondent to a current which flows through a gate load resistor RL1. The current tC1 induces a current iC2 which flows between the anode and the cathode of the light emitting thyristor T1. The current iC2 is as large in intensity as the product of the current iC1 and a current amplification factor beta.

Filed: 1991-09-27
Abstract: PURPOSE:To discharge the foaming beverage in the filled condition in the vessel without overflowing of the foaming beverage from the vessel and control the foamed volume appropriately and further, always pour it in a stable condition. CONSTITUTION:A vessel 19 is made slant at a previously designed angle from the mount bed 26 of the vessel 19. And the foaming beverage is poured, while suppressing the foam along the wall of vessel 19. By detecting the fact that the foam or the liquid level comes to rise up to the first level previously set by the level detector 31, the mount bed 26 is returned to an erected state to pour the liquid by the level difference from the liquid outlet 8 to obtain a necessary foaming volume. If a computed pouring time is finished before the foam rises up to the second liquid level, the pouring valve 6 is closed and a valve 7 for foam is opened to give foam up to the second level to finish pouring. Or when the foam or liquid level rises between the second liquid level before the calculated pouring time is finished, the pouring valve 6 and the valve 7 for foam are closed. In this way, when the liquid reaches finally the previously determined level in the vessel 19 in the erected condition of the vessel 19, the liquid is forced to cease its pouring.
