Filed: 1979-05-08
Abstract: PURPOSE: To change a dictionary part over through the operation of a dictionary selection key and also to indicate sequential display of homonyms, by equipping the dictionary selection key while sectioning the dictionary memory into dictionary parts.  
     CONSTITUTION: Dictionary memory 1 is partitioned into #0W#N dictionary parts and dictionary selection key 23-0 is pushed to use dictionary part #0. When hiragana (Japanese syllabary) is input by using key 22, the word is stored in character buffer 5 and the depression of a punctuation key starts retrieval processing to attain access to dictionary 1. The memory contents of dictionary part #0 are read out from address "0" and compared to those of character buffer 5 and, when the both agree with each other, are displayed on display unit 8. If one word has homonyms in this case, key 23-0 (or in-use dictionary selection key 24) should be depressed to read and display the contents of dictionary part #0 at the next address.

Then, the lifting pins rise up to the original position of the base plate 12. There, a nitrogen gas is blown from the nozzles of the air-feeding tubes 23 to the surface of the base plate to accelerate the cooling of the base plate. After cooling, the base plate 12 is taken out of the opening 9.

Title: Synthesis of silica multicomponent powder
Inventor: OKUYAMA MASAHIKO
IPC: C01B33/20
Filed: 1990-03-09
Abstract: PURPOSE:To obtain uniform powder having excellent particle diameter and particle size distribution free from deviation from the objective composition by reacting an alkoxy group-containing silica multicomponent compound precursor with an alcohol under reflux and hydrolyzing. CONSTITUTION:A silica multicomponent compound precursor containing an alkoxy group, Si and one or metallic atoms except Si is formed. Then the precursor is reacted with an alcohol having >=3C, preferably 3C or 4C under reflux and the alkoxy group of the precursor and alkoxy group of the alcohol are subjected to interchange reaction. Then the resulting solution is hydrolyzed with water and powder is precipitated to give the objective powder. In order to readily carry out the reaction in the synthesis of the compound precursor, the reaction is generally done in a solvent. A lower alcohol such as ethanol or methanol is preferable as a solvent in the case of a starting raw material containing a metal simple substance, an organic salt or an inorganic salt because alkoxide formation reaction and formation of compound precursor are readily carried out and the lower alcohol is preferable in terms of cost.

Abstract: PURPOSE: To achieve the higher friction resistance of the portions to become thin and the portions in contact with other members and less working processes by applying forging to the members of the bayonet members coupling with the coupling parts on the camera side without depending upon machining.  
     CONSTITUTION: A bayonet member 6 fitted to a holding ring is provided to the lens-barrel and undergoes fastening to the bayonet jaws on the camera side. A spring member 16 is fixed to the member 6 to absorb the fitting looseness of the time when the lens is mounted to the camera. This member 6 is constituted of the respective three bayonet jaw parts 6A and other parts 6B by leaving a spacing of 120° on the circumference and the jaws 6A on the lens side are engaged with the jaws on the camera side. Forging is applied to these jaw parts 6A and 6B. As a result of this, they withstand the abrasion owing to the slide contact turning of the coupling members on the camera side. Even more, working processes may be reduced because they do not depend upon machining and hard materials such as stainless steel may be used as well.
