Inventor: OSAWA TAKASHI
IPC: G11C29/00
Filed: 1993-03-12
Abstract: PURPOSE:To obtain a semiconductor memory with built-in a test mode capable of changing the widths of parallel test bits by simultaneously activating column select buffer circuits whose number is more than the number normally required. CONSTITUTION:Signals REF8k, REF4k and REF2k are inputted into a QSEL generating circuit of a column select (DQ) buffer control signal generating circuit and it is made to a refresh mode. Furthermore, the selection capability is negated for prescribed address signals A8c, the inverse of A8c, A9c and the inverse of A9c and plural DQ buffers connected to same data read/write (RWD) lines are simultaneously activated. Thus, RWD line pairs are wired OR connected, data operation results, whose number is more than the number of the RWD line pairs, are read to the RWD line pairs and the widths of many bits are made wider. Therefore, a test mode, in which widths of parallel test bits are freely changed, is incorporated, the widths of contraction bits are increased, and testing time is drastically shortened.

IPC: C02F11/04
Filed: 1982-03-29
Abstract: PURPOSE:To improve control and workability, by detecting the component of fermenting gases and providing an indicator which indicates the conditions for continuing combustion in apparatus for burning of fermenting gases or the state of the digesting liquid in a methane fermentation tank. CONSTITUTION:The concn. of methane in a methane producer is measured with a gas sensor 103 consisting of a gas sensitive element 103 having the characteristics that the electrical resistance thereof is decreased by the reversible reaction with mathene in about 400 deg.C atmosphere. When the concn. of the methane decreases to the low concn, i.e., <=55%, at which the continuation of combustion is infeasible, a lamp 109 of an indicator 107 is lighted and when the concn.  increases above said value, the lamp is put out. When the digesting liquid 6 is  overloaded, the concn. of the methane decreases; therefore, the overloading of  the digesting liquid can be announced similarly to the user of the methane producer by lighting of the lamp 109. Thus, the user is able to control the operation of the methane fermentation tank 1 in the optimum state of the digesting liquid by itself.

When, during generation of a peak output l, alpha attains a set value A previously stored in a memory 20 at each kind of an object to be cooked, a time T1 is latched by a counting part 18 and is outputted to a calculating part 19. Meanwhile, weight data is sent to the calculating part 19 from a weight detecting part 30. The calculating part computes and decides a time T2 between the time T1 and completion of heating.
