Abstract: PURPOSE:To reduce energy consumption by supplying power only to circuits at one part when waiting for a transmitting signal excepting for the time of receiving and transmitting the transmitting signal. CONSTITUTION:When a periodic signal in the transmitting signal is detected by a signal level detection part 5 of a reception circuit 22, a transmission detecting signal 12 is outputted from the signal level detection circuit 5.

Title: Light phase modulator
Inventor: SHIMIZU HARUHITO
IPC: G02B6/00
Filed: 1988-12-23
Abstract: PURPOSE:To obtain stable operation as the optical phase modulator by compensating the temperature dependency of the light phase variation characteristic of a fiber lateral pressure gauge for phase modulation to an input voltage by using a fiber lateral pressure gauge for temperature compensation. CONSTITUTION:The fiber lateral pressure gauges 104 and 105 for phase modulation and temperature compensation vary in temperature and then forces to the single-mode fibers 103 of both the lateral pressure gauges vary by an equal quantity, so that light beams passing through both the lateral pressure gauges 104 and 105 are shifted in phase by an equal quantity between orthogonal polarized light beams. The variation in phase difference between the polarized light beams of the light beams passed through both the lateral pressure gauges 104 and 105 due to the temperature variation is canceled. Namely, the phase variation of light which is caused when a constant voltage is applied as a modulating signal to the lateral pressure gauge 104 is constant irrelevantly to the temperature and this light phase modulator operates stably.

Title: Continuous air-swept type planetary bowl mill
Inventor: KANEKO KANTARO
IPC: B02C17/18
Filed: 1990-11-27
Abstract: PURPOSE:To obtain products having a good particle size distribution by partitioning a grinding chamber with a partition plate, which is installed at the exit side of the grinding chamber of each mill pot and allows only the ground materials to pass through, and covering the circumference of the tips of the plural number of discharging parts provided radially from a passage part with a non-rotating discharging chute. CONSTITUTION:Only the ground materials which are ground well in the mill pots to become a product F are lifted through an air-swept action and sucked to move into an adjacent product discharging part 7 through a passing hole 32 in the center of the partition plate 31. Grinding media having a large weight or particle size or unground materials, however, are prevented from reaching the passing hole 32 because of centrifugal force. In the product discharging part 7, discharging pipes, 72A, 72B, 72C, 72D which are attached radially from the axis of rotation perform rotation similarly as the mill pots. Since the circumference is completely covered with the non-rotating discharging chute 73, on account of this relative rotating motion, a pressure gradient that is lower toward the direction of circumference is produced, compounded further with a negative pressure gradient which originally forms the air-swept action leading to a product collecting part, and generates a phenomenon which enhances such action.

Title: Sludge treatment
Inventor: MIYAZAKI NOBUYUKI
IPC: C02F11/14
Filed: 1987-12-25
Abstract: PURPOSE:To promote flocculation of sludge flocks using residual polymers in a separated return liquid without the need to add a flocculant in a sludge concentration process and increase the recovery rate of the flocks by returning the separated liquid treated by dehydration with the addition of a high polymer flocculant in a dehydration process, to the sludge feed side of a sludge concentration process. CONSTITUTION:Sludge discharged from a sludge concentration process is introduced, either after digestion or directly, into a dehydration process, and a high polymer flocculant is added to this introduced sludge for dehydration. The separated liquid from the sludge concentration process is introduced into a water treatment process, either alone or together with a separated liquid obtained after digestion. In the water treatment process, the separated liquid is biologically treated. At that time, the separated liquid discharged from the dehydration process is returned to the sludge feed side of the sludge concentration process and the flocculation of the flocks is promoted with the help of residual polymers contained in the separated return liquid to improve the flock recovery rate. As a result, the concentration of the separated liquid is kept at low level and at the same time, the density of the concentrated sludge is increased.

Title: Container for photographic sensitive material and its production
Inventor: AKAO MUTSUO
IPC: B29L9/00
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To economically suppress an increase in the surface temp. due to irradiation of sun rays without decreasing the photographic characteristics of a photographic sensitive material. SOLUTION: A cartridge body 13 consists of an upper case 11 and a lower case 12. Each of the upper case and the lower case 11, 12 is formed by injection molding of a black synthetic resin compsn. into which a light-absorbing and shielding material is kneaded. The outer surface of each case is coated with a light-reflecting material to form a white reflection layer 11a, 12a. Since the light which irradiates the cartridge 13 is scattered by the reflection layers 11a, 12a, the cartridge body 13 does not absorb heat, which suppresses the temp. increase on the surface and inside.  Or, the upper case and the lower case 11, 12 may be formed by injection molding of a synthetic resin compsn. prepared by kneading a light- reflecting material with a thermoplastic resin, and then a light-absorbing layer may be formed on the inner faces of the formed bodies by applying a light-absorbing and shielding material. Or, a first synthetic resin compsn. prepared by kneading a light-absorbing and shielding material in a thermoplastic resin and a second synthetic resin compsn. prepared by kneading a light-reflecting material with a resin may be used together for injection molding in a two- color injection molding machine so that the first synthetic resin compsn. is formed as the inner face side.
