Abstract: PURPOSE: To provide a vapor fuel concentration measuring device which has a structure suitable for use in a fuel supply system for the engine of an automobile, etc., and has high reliability and measuring accuracy. CONSTITUTION: An ultrasonic wave generating portion 22 is made to project an ultrasonic wave at an ultrasonic wave propagation chamber 9 by a burst signal B synchronized with the period of the signal Sm of a dividing circuit 33, and a synthesizing circuit 39 produces a composite signal E of a signal C of the reflected ultrasonic wave and a signal synchronized with the signal Sm.

Title: Radiator for magnetron
Inventor: TANAKA HIROYOSHI
IPC: H01J23/033
Filed: 1985-10-18
Abstract: PURPOSE:To construct fins having good radiation performance by folding the side section of a radiation fin parallel with the air flow while arranging a plurality of band type raising sections, where the sides facing against the air flow are raised and opened on the radiation fin around the side and the rear section of the anode side section, and fixing them to the folded side section of the fin. CONSTITUTION:Since raising sections 11 are provided, the pressure loss of the air flow passing through said sections 11 will increase while simultaneously the air flow will decrease thereby the wind flow at the section provided with no raising sections 11 will increase correspondingly. Consequently, the air flow toward the center of a radiation fin 9 is induced gradually at the rear stream side of an anode or a fin collar thus the dead water area 13 reduces considerably. Since the foot part of the raising section 11 has obliquely constructed joint side 14 to provide an elevation angle against the air flow, the air flow will vary abruptly at the foot part to cause turbulence, increasing the heat conductivity. While since the raising sections 11 are connected to the side section 10 of the fin, the efficiency of fin radiation is improved, lowering the entire thermal resistance of the fin 9 resulting in reduction of the temperature nonuniformity around the anode.

The solid is porous and may be capable of absorbing at least 0.6 cm<3> of ethanol per gramme of solid. The particulate solid may be obtained by spray drying a non-particulate material, preferably by comminuting the non-particulate material in the presence of a liquid medium, and desirably an attrition inhibitor, and spray-drying the comminuted mixture. The particulate solid can be reacted with a transition metal compound such as titanium tetrachloride and preferably with a Lewis Base compound such as the ester of an aromatic carboxylic acid. The transition metal composition obtained is useful for the production of olefin polymerisation catalysts of high activity and stereospecificity. The polymers obtained have an essentially spherical particle form and are porous, for example having a porosity of at least 0.2 cm<3>/g as measured by mercury porosimetry. The polymers typically have a mean particle size of at least one millimetre.

Title: Pattern recognizer
Inventor: FUJII HIROMI
IPC: G06K9/62
Filed: 1984-11-08
Abstract: PURPOSE:To detect assuredly even a pattern having the faltering or the stagnation of a pen by checking the possibility from the value obtained through a distance calculating part for a fact that a termination candidate is equal to a termination and changing the termination detecting parameter based on the result of said checking. CONSTITUTION:Receiving a termination candidate detecting signal C2 from a detecting part 2, a minimum value circuit 21 reads the distances between the input patterns obtained by a time point E' and all standard patterns out of a distance calculating part 5 to obtain the minimum distance. A comparator 22 compares said minimum distance with the prescribed threshold value. Then it is decided that the possibility is small for a fact that a termination candidate is equal to a termination when the minimum distance is larger than the threshold value. Thus a parameter L2a of a termination detecting parameter memory part 23 is sent to the part 2. The part 2 uses the parameter L2a uses as the termination detecting time width for detection the termination. When the minimum distance is smaller than the threshold value, it is decided that the possibility is large for a fact that the termination candidate is equal to the termination. Thus a parameter L2b is sent to the part 2, and the termination is detected in the same way.
