Title: Garbage drying and treatment device
Inventor: NEKOTSUKA TADAAKI
IPC: F26B11/14
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To decrease the height dimension of an entire device and easily carry out an operation for charging garbage by providing a rotating and driving means for driving an agitating member on the side part of a heating tank and connecting the rotating and driving means to the agitating member by a rotation transfer means. SOLUTION: A motor 28 for driving an agitating memeber is arranged on the side part of a heating tank 25 so that a rotation is transmitted by a chain 60 and sprockets 58 and 59. Thus, the entire height of a device can be decreased to a low height substantially corresponding to the height of the heating tank 25 and the position of a dust hopper is lower than that of a conventional one so that an operation for charging garbage can be easily carried out. A longitudinal condenser 32, a deodorizing heater 33 and a heat exchanger 34 are arranged on the side part of the heating tank 25 and these members are connected together by pipes 67, 71, 73 and 81. Thus, the dimension of the entire device housed in a housing 41 can be made smaller to achieve space gaving.

Title: Photodirectional coupler
Inventor: MIKAMI OSAMU
IPC: G02F1/035
Filed: 1977-11-07
Abstract: PURPOSE:To realize maximum strength ratio while keeping constant the voltage applied to the front part and rear part of the coupling part, by shifting the dividing ratio of the coupling part, or the dividing ratio of the electrode, by the extent corresponding to the intitial phase difference between waveguides. CONSTITUTION:The coupling part is divided into two parts, of which lengths should be respectively l1 and l2. Their relation should be deltal=l1 - l2. The initial phase difference of propagation constant of two waveguides should be deltabeta0 = beta1 - beta2. Electrodes 4-2, 4-3 are commonly grounded, and the same voltage is applied to electrodes 4-1, 4-4 from outside. Phase differences equal in size and differing in sign, DELTAbeta(E) and -DELTAbeta(E), are applied between the waveguides, before and after the coupling part. At this time is found the presence of dividing deviation deltal which maximizes the strength ratio when deltabeta0   0. Therefore, after determining the initial phase difference deltabeta0 by preliminary experiment, when the electrodes are made by deducing the dividing deviation deltal corresponding to side phase difference, the maximum strengh ratio may be realized while keeping constant the voltage applied to the electrodes 4-1, 4-2.

Protecting layers are formed on the recording layers of the substrate group and dummy substrate by a protecting layer formation apparatus. Thereafter, the reflectance of the recording layer of the dummy substrate is measured.  A film thickness of the protecting layer is obtained from the measured value and the reflectance before the protecting layer is formed on the basis of a preliminarily experimentally obtained relationship of a film thickness and a reflectance change before and after the protecting layer is formed. A condition when the protecting layer is formed next is regulated in accordance with the film thickness.

Abstract: PURPOSE: To obtain anthraquinone in one step in a high yield, by bringing a gas containing phthalic anhydride and benzene into contact with a catalyst consisting of titanium oxide and/or tin oxide, using CO 2  as a reaction diluent.  
     CONSTITUTION: Phthalic anhydride (P) is reacted with benzene (B) in a molar ratio of (P) to (B) of about 1:3W30 in the presence of a catalyst consisting of titanium oxide and/or tin oxide at 300W600°C, preferafbly 350W550°C to give anthraquinone. The optimum reaction temperature depends on the feed rate, e.g. gas space velocity (SV), of the raw material to the amount of the catalyst used, and the temperature is set at a higher one with increasing SV. The temperature is lower with decreasing SV. The use of CO 2  as a diluent inhibits decarboxylation of phthalic anhydride to increase the yield of the title compound.

Title: Valve operating mechanism for 4-cycle engine
Inventor: MATSUURA MASAAKI
IPC: F02B75/02
Filed: 1986-06-11
Abstract: PURPOSE:To improve the durability of a valve operating mechanism, by providing a cam rotation resisting means for suppressing the relative rotation of a valve operating cam to a cam shaft under inoperative condition of an integral operating means for integrally operating the cam with the cam shaft according to an operational condition. CONSTITUTION:Integral cams 12 and 13 are engaged with cam shafts 5, and cylinder chambers 15 and 21 are formed in the cam shafts 5 at the engaged positions of the cams 12 and 13. A lock plunger 16 is engaged in the cylinder chamber 15, and the cam 12 is lockable by projecting the plunger 16. On the other hand, a damper 22 is engaged in the cylinder chamber 21, and a cam surface 36 is formed on the inner surface of the cam 13 opposite to the damper 22. When the cam 13 is rotated relative to the cam shaft 5 in a direction where the rotation of the cam 13 is retarded from the rotation of the cam shaft 5, the damper 22 is projected to promote the relative rotation. In contrast, when the rotation of the cam 13 is advanced from the rotation of the cam shaft 5, the damper 22 is retracted to discharge a pressure oil in an oil chamber 25, thereby suppressing the relative rotation owing to the flow resistance in discharging the pressure oil.
