Abstract: PURPOSE: To prepare the titled compound useful as a raw material of pharmaceuticals, etc., easily, safely and economically in an industrial scale, by reacting an α-thiocarbonyl compound with a propargyl compound in the presence of a metal carbonate or a metal bicarbonate.  
     CONSTITUTION: The allene derivative of formulaI(R 1  is alkyl, etc.; R 2  is H, alkyl, etc.; R 3  is H, alkyl, etc.) is prepared by reacting an α-thiocarbonyl compound of formula II with a propargyl compound of formula III (X is halogen or sulfonate group) in the presence of a metal carbonate or a metal bicarbonate (e.g. an alkali metal or an alkaline earth metal salt such as Na 2 CO 3 , NaHCO 3 , etc.). Equivalent amount of the metal salt based on the compound of formula III is sufficient for the purpose; however, larger amount of the salt may be used. The amount of the compound of formula III is equimolar to the compound of formula III. When water is present in the reaction system, the yield can be improved by using ≥1mol, pref. ≥1.3 equivalent of the compound of formula III.

Title: Focus detector
Inventor: ANDO HIDEO
IPC: G11B7/1381
Filed: 1989-01-31
Abstract: PURPOSE:To easily regulate the assembly of an optical system and to correctly and stably detect a focus by forming an optical member which applies the abration approximate to the coma abration to a light beam with a simple shape. CONSTITUTION:Since an optical path length converting means 14 can change the pattern of a light beam spot on a photo detecting means 16 only by applying optical path length different at every ray constituting the light beams from a picture recording medium 12, the optical path length converting means 14 can be made into a mechanically simple shape. Consequently the optical path length converting means 14 can be arranged in an arrangement relation at comparatively large allowable level in the optical system. Thus the focus detector, which has a stable detecting characteristic, a simple constitution and whose assembly regulation is facilitated, can be obtained.
