Title: Production of thickness distributed film
Inventor: TODOKORO YASUYUKI
IPC: G03C5/08
Filed: 1987-08-07
Abstract: PURPOSE:To easily obtain a thickness distributed film having high stability by forming a reaction product of photoreaction in a photoirradiated region by heating and photoirradiation and moving a photoreactive material from the unphotoirradiated region to the photoirradiated region by this reaction product of photoreaction, thereby changing the film shapes between the unphotoirradiated region and the photoirradiated region. CONSTITUTION:The thickness distributed film 5 which is different in the film shape in the photoirradiated region R where the reaction product m of photoreaction is formed from the photoreactive material M with respect to the unphotoirradiated region Q if light 4 is locally projected by using a mask 3 to the film 1 contg. at least the photoreactive material M simultaneously with heating to a suitable temp. by using a heater 2 after said film is formed. The development of seepage and the swelling by the photoirradiation are thus accelerated by the heating, by which the time for producing the thickness distributed film 5 is shortened. The utilization of the photoreactive material M which is heretofore difficult to move in the film 1 due to the large size of the molecules is thereby enabled and the entanglement with a binding polymer is more intricated. The stabler thickness distributed film 5 is thus obtd.

When the switch 13 is operated successively, an alarm time obtained by further addition is displayed, while a set state of the alarm is brought forth and an alarm setting mark 15 is displayed. When the current time passes in the set state of the alarm and reaches the alarm set time, the alarm is sounded and the same time is displayed in the areas 11 and 12 after the sounding, while the alarm is put in the non-set state. In other words, the alarm is sounded only at the set display time and it is not sounded thereafter until it is set again.

Title: Heat pipe and humidifier equipped with heat pipe
Inventor: ONO SHUNSUKE
IPC: F28D15/02
Filed: 1984-09-26
Abstract: PURPOSE:To permit to increase the amount of humidifying by increasing the transferring amount of heat and preventing the reduction of enthalpy of water by a method wherein water is supplied to a water absorbing member, provided at the outer periphery of the heat pie, continuously while air is ventilated to the member to evaporate the water. CONSTITUTION:Water 5 in a tank 8 is sucked up to the water absorbing members 6 at the outer periphery of the heat pipe 6 continuously by capillarity and is evaporated at the upper part of the heat pipe 6 by contacting with the ventilated air from a fan 7 and, whereby, the movement of water is effected continuously. In this case, operating fluid, sealed in the heat pipe 6, is vaporized and moved to the upper part of the pipe, then, is condensed and returned to the lower part of the pipe, whereby the heat is moved continuously. Evaporating latent heat is deprived from the sucked water upon evaporation, however, the enthalpy of the water is increased by the heat transferred by the heat pipe 6 and the partial pressure of water vapor is increased whereby the amount of humidifying may be increased.

Title: Improvent in production of superabsorbent polyacrylate
Inventor: SHIYUU RON REEBURU
IPC: C08F2/32
Filed: 1993-08-11
Abstract: Charges of acrylic acid monomer which are overneutralised and underneutralised in relation to the degree of neutralisation of the final polymer are employed successively for the preparation of superabsorbent powders consisting of partially neutralised polyacrylic acid by a process including the formation of a polymer gel by a first polymerisation of monomer in inverse suspension followed by the polymerisation of a second monomer charge absorbed in this gel. The powders thus obtained consist of particles of spheroidal shape. It is very advantageous to conduct this process with the aid of emulsifiers which are suitably chosen to enable the stage of absorption of monomer by the intermediate gel to be carried out at temperatures of the order of 35-45 DEG C.

Abstract: PURPOSE:To follow up a curve to surely execute autonomous travel control by changing the image pickup direction of an image pickup means mounted on a vehicle in accordance with traveling environment. CONSTITUTION:An obliquely observed image picked up by cameras 101, 103 in an image information processing part 100 is supplied to an image processing computer 105 and converted into a reversely obliquely observed image so that the converted image goes to a plane image in a world coordinate system. A pair of traveling lines R, L are extracted on the plane image by the computer 105. A reference line Lr rectangular to an advancing direction is formed on a front position by a prescribed distance Yr from a self-behicle 900 so as to intersect with the extracted traveling lines L, R. The lines L, R intersect with the line Lr at points A, B. When the current position of the vehicle 900 is defined as an origin and a direction rectangular the advancing direction and the advancing direction are respectively defined as X and Y, whether the vehicle is protruded from the lines R, L or not is calculated. Thus, the traveling lines L, R can be catched within the obliquely observed image by controlling the directions of the cameras by means of steering angles.
