Title: Concrete spray device
Inventor: USUKI KATSUKO
IPC: E02D17/20
Filed: 1992-01-31
Abstract: PURPOSE:To efficiently accelerate a concrete material by compressed air without allowing friction force to act on the concrete material from the inner peripheral surface of a feed hose by supplying compressed air going toward a spray nozzle to the outer peripheral part of a feed passage in the vicinity of the discharge port of a sprayer. CONSTITUTION:The concrete material M reaching the area immediately before a discharge port 18 is allowed to flow to the feed passage R formed in a feed hose 4 by the compressed air A from an air jet part 21 through the discharge pipe 24 within a booster 22. Whereupon, since the compressed air from an air jet pipe 25 has kinetic inertia parallel to the rib 17b of a bottom plate 17 at the position close by the discharge port 18, the rib 17b hardly obstructs the flow of compressed air. Therefore, the concrete material is efficiently accelerated from a sprayer and the length of the feed hose 4 can be extended.

Title: Electro-acoustic converter
Inventor: KAMEYAMA AKIRA
IPC: H04R17/00
Filed: 1986-01-27
Abstract: PURPOSE:To obtain a converter which performs nondirectional transmission at a low voltage by using an entire-surface electrode as one of the internal and external surface electrode of a vibrator and split electrodes as the other, and connecting the split electrodes in parallel. CONSTITUTION:The entire-surface electrode 2 is provided on the outer diameter surface of a cylindrical piezoelectric element and the split electrodes 3a-3d are provided on the inner diameter surface. Then, the opposite electrodes 3a and 3c are connected to the primary side terminal of a balanced type transformer 4a and the electrodes 3b and 3d are connected to the primary side terminal of a balanced type transformer 4b. Then when a signal is led out of between the neutral point between the transformers 4a and 4b and the entire-surface electrode 2 on the outer diameter surface, signals of translation vibration which are opposite in phase between the opposite split electrodes cancel each other. Consequently, nondirectional transmission becomes possible between terminals 7a and 7b. Electric capacitors formed between the split electrodes 3a-3d and the entire-surface electrode are all connected in parallel between the terminals 7a and 7b, so the impedance of the converter decreases, so that the converter which performs nondirectional transmission at a low voltage is obtained.

Title: Piezoelectric tremoring device
Inventor: HARA ATSUSHI
IPC: F16H49/00
Filed: 1987-01-26
Abstract: PURPOSE:To improve the expansion and contraction efficiency of a clamp body, by furnishing a main body in which a shaft is penetrated, and a clamp body holding member which extends from the main body in the direction almost vertical to the shaft, with its top fixed to the clamp body, and furnishes plural arms elastic in the direction of the expansion and contraction of the clamp body. CONSTITUTION:When a voltage is applied to the piezoelectric element of a clamp body 2 and the clamp body 2 is contracted to make its inside diameter smaller, the top 32 of a clamp body holding member 3 receives a stress in the arrow directions, that is, in the directions to the center axis, arms 31 are bent, and the top 32 is moved in the direction of the stress. This is because the arms 31 almost parallel to the center axis direction have the elasticity almost vertical to the center axis. Therefore, the contraction efficiency of the piezoelectric element of the clamp body 2 is extensively large. And moreover, since the arms 31 of the clamp body holding member 3 have a length approximately parallel to the center axis or the shaft 1, they have a rigidity against the stress in the axial direction of the shaft 1 resulting from the expansion and the contraction of a shaft driving body 4, and the efficiency to tremor the shaft 1 by the expansion and contraction amount of the piezoelectric element is not reduced.

Filed: 1993-01-08
Abstract: PURPOSE:To obtain an operation apparatus, provided with a load circuit, wherein the minimum operating voltage of a processor module can be designed to be high by a method wherein the processor module is separated from an electric element whose consumption power is comparatively large and the voltage of the processor module is held by a capacitor. CONSTITUTION:While a start signal 7 is at an 'H' level, a PMOS transistor 6 is on, a processor module 2 is not operated and a capacitor 7 is charged by a no-load power-supply voltage 14. While the start signal 7 is at an 'L' level, the PMOS transistor 6 is off, the processor module 2 is operated during this time, and a voltage 15 which is held by the capacitor 5 is reduced in a discharge curve determined by an electric current leaked to the processor module 2 from the voltage 15. However, when the capacitance of the capacitor 5 is designed to be sufficient, a minimum operating voltage 12 is ensured. Then, even when a power-supply voltage 11 is dropped when a heater 1 is turned on, the voltage 13 of a constant-voltage circuit 25 is not affected, and the operation of the processor module 2 is guaranteed. Consequently, the minimum operating voltage can be designed to be high.

Inventor: NIIHARA TAKAMIZU
IPC: H04L1/00
Filed: 1987-01-29
Abstract: PURPOSE:To improve a proportion of data error detection and correction of reception data by setting a known certain value as unused data in the idle area on the memory map of a first memory on the transmission side not to transmit unused data. CONSTITUTION:An idle area other than the storage area of a digital signal consisting of data to be transmitted to a transmission line 5 and parity is generated on the memory map of the first memory 2, and unused data in this idle area is preliminarily set to a known certain value and is used only as a parity generating element and is not transmitted to the transmission line 5. Consequently, a proportion of effective data in a block is increased. On the reception side, the same known certain value is independently written in the idle area on the memory map of the second memory 9 as untransmitted unused data. Consequently, reception data error is detected and corrected based on the written certain value and the reception digital signal. Thus, transmission error of unused data does not occur at all.
