Patent JP-S58101270-A (JP)
Title: Concrete pump
Inventor: SAKAI KENJI
IPC: F04B15/02
Filed: 1981-12-10
Abstract: PURPOSE:To transmit force of a hydraulic cylinder to an oscillating pipe efficiently, by dividing the oscillating pipe into two parts, one side proximate to a concrete cylinder and the other side distant from it, while making each other's axial displacement to be absorbed in order. CONSTITUTION:The end part of a discharge conduit 8 is inset in the concave part of a driving plate 7 via a flange part 8a so that it can no longer move in the axial direction and accordingly clearance between this end part and a guide 6 will not be increased at all even if pressure for feeding concrete rises. At this time, an upper discharge conduit 9 at the other side carries out an oscillating motion centering on the axis of a conduit 11 and since axial displacement between the lower discharge conduit 8 and the upper discharge conduit 9 is absorbed by sliding of an overlapped part between the lower discharge conduit 8 and the upper discharge conduit 9, force of a hydraulic cylinder is efficiently transmitted to an oscillating pipe.

Title: Radio receiver
Inventor: SHIMIZU HIROYUKI
IPC: H04B1/74
Filed: 1987-08-07
Abstract: PURPOSE:To eliminate unnecessary switching when abnormality occurs to a transmission side by providing a switching decision means which decides whether or not the receiving operation of a 1st receiving circuit to a 2nd receiving circuit according to the state of an alarm signal. CONSTITUTION:A switching decision circuit 103 consists of a delay circuit 117. When an alarm circuit 102 detects abnormality and generates an alarm signal, this signal is delayed by a constant time through a delay circuit 117 and then inputted to a control circuit 112 to switch the 2nd receiver 12. If the alarm signal is ceased within a constant time, the alarm signal is not transmitted to the control circuit 112 the constant time later and the switching operation is not performed. Consequently, complicate operation wherein resetting operation is performed by judging whether or not the abnormality occurs on the reception side owing to switching to a stand-by receiver while the reception side is normal can be evaded.

Title: Sheet stacking device
Inventor: TAKASHIMA KAZUNORI
IPC: B65H1/04
Filed: 1992-06-30
Abstract: PURPOSE:To make paper feed pressure of a sheet stacking device approximately constant so as to enable stable paper feed. CONSTITUTION:A sheaf of sheets is stored in a cassette 1 in such a state that the sheet tip part comes in contact with a front reference plate 12 in the cassette 1. At the time of feeding the sheets, the front reference plate 12 moves in the direction of being separated from the sheet tip part by a driving means (stopper) 15. Accordingly, there is no contact action between the sheet tip part and front reference plate 12, so that the resistance of the front reference plate 12 to the sheets is reduced to enable stable paper feed.

IPC: H04N1/40
Filed: 1985-09-06
Abstract: PURPOSE:To make a TV display of high resolution and also to perform screen projection and image copying by a photosensitive body through a simple constitution by imposing intensity modulation upon the luminous flux of a linear light source by a liquid crystal shutter, and writing an image on a liquid crystal panel and forming a latent image on the photosensitive body. CONSTITUTION:The luminous flux 2 of the linear light source 1 is intensity- modulated by the liquid crystal optical shutter 3 into luminous flux 2', which is reflected by a rotary polygon mirror 4 to write an image on the liquid crystal panel 5, so that the image is projected on a screen 7 through a projection optical system 12. Part 2'' of the luminous flux, on the other hand, is reflected by a mirror 8 and converged on the photosensitive body 9 to transfer and fix a visible image on paper 11. Therefore, the TV display and screen display of high resolution become possible even when the shutter 3 which operates at a high speed is used, a display screen can be copied when necessary, and the liquid crystal shutter 3 and liquid crystal panel 5 are inexpensive, so the device is manufactured at low cost.

IPC: B01J23/74
Filed: 1990-07-30
Abstract: PURPOSE:To lower the reaction temp. and to reduce a cost by first desulfurizing by lime-gypsum method and then denitrating by selective contact reduction method. CONSTITUTION:First, an exhaust gas is desulfurized by lime-gypsum method comprising steps of SO2 absorption, oxidization, neutralization and crystallization of gypsum especially with using a jet-bubbling reactor. Further, ammonia is preliminarily added to the exhaust gas in the upstream of the desulfurization process so that the amt. of SO3 in the exhaust gas is reduced to about <=10mg/Nm<3>. Then ammonia gas is introduced to the exhaust gas, which is denitrated by selective contact reduction method in which the exhaust gas is brought into contact with a catalyst at low reaction temp. This catalyst consists of an alumina carrier such as gamma-alumina and active metals such as molybdenum, vanadium, etc., deposited on the carrier. In this process, heat exchange is performed between steps of descending temp. on introducing the exhaust gas to the desulfurizing equipment and raising temp. on introducing the exhaust gas to the denitrating equipment with using an indirect heat exchanger using steam as the heat medium, or the like. Thereby, the treatment can efficiently be performed at a low cost.
