Title: Differential amplifier circuit with emitter follower
Inventor: SHINOZAKI EIJI
IPC: H03F3/45
Filed: 1991-07-16
Abstract: PURPOSE:To reduce the input capacity of the differential amplifier circuit pre- installing an emitter follower circuit. CONSTITUTION:Transistors Q15 and Q16 and constant current sources I14 and I15 are added to the differential amplifier circuit pre-installing the emitter follower circuit and by setting the current values of constant current sources I11 and I12 larger than the current values of the constant current sources I14 and I15, potential difference between the base and emitter of the transistors Q15 and Q16 is fixed so as to form a level shift circuit. Therefore, by fixing the potential difference between the base and collector of transistors Q13 and Q14 constituting the emitter follower, there is the effect of preventing the capacity between the base and collector of the transistors Q13 and Q14 from being practically operated as capacity.

Title: Semiconductor integrated circuit device
Inventor: ARIMOTO MASAO
IPC: H01L21/76
Filed: 1987-07-13
Abstract: PURPOSE:To secure a paired state and to realize the high integration by a method wherein islands to be paired with each other are arranged diagonally and, even when a potential of one of these islands is reversed, an operation of a parasitic transistor formed by these islands and by a separation region is prevented. CONSTITUTION:An island 1 which is set to a high potential in relation to a lowest potential (a separation potential) and an island 4 whose potential may be reversed by an inductive load or the like are arranged in a diagonal direction in a lengthwise and breadthwise arrangement. Because the islands 1, 4 are arranged in the mutually diagonal direction, the island 1, a separation region 6 and the island 4 are used as a collector, a base and an emitter, respectively. A width of the base of a parasitic transistor 8 is expanded; even when the potential of the island 4 is reversed, an electric current is hardly flows to the parasitic transistor 8; an operation of the parasitic transistor 8 is prevented effectively. By this setup, while the operation of the parasitic transistor is being prevented, the islands to be paired with each other can be arranged closely, a required area can be reduced and the high integration can be secured.

Abstract: PROBLEM TO BE SOLVED: To accurately detect the key and the chord by dividing the melody of playing data into inspection sections. SOLUTION: Melody data are divided into phrases #1 to #N. Then, each phrase is divided into one bar or two rhythm chord rhythms #11 to #1M,..., ξN1 to #NL according with the number of notes and the length of notes. Then, harmonic sounds are extracted from each chord rhythm section. Based on the extracted harmonic sounds, chord rhythms are connected, if required, and the section changed chord rhythms ξ11 to ξ1M',..., #N1 to #NL' are made into detection sections for key detection. Then, harmonic sounds and pitch name columns are extracted for every detection section. Based on the extracted harmonic sounds and pitch name columns, a candidate melody is extracted. Then, the key for the detection section is determined from the extracted candidate key.

Abstract: PURPOSE:To prevent an engine stall from occurring, by decreasing an asynchronous injection quantity as compared with time of a neutral range when a range other than being neutral is selected in an automatic transmission in conducting the asynchronous injection in time of acceleration or the like. CONSTITUTION:In time of engine operation, a control circuit 22, in its asynchronous injection routine, first a difference DELTAPM in new and old values of the suction pipe pressure PM measured and read out of a pressure sensor 20 at every specified time is found, then a difference DELTADELTAPM in these new and old values is found and stored in memory.

And, when it is so judged as to be the engine transient state, a fact of whether a range other than being neutral is selected or not is judged in the case where it is a car fitted with an automatic transmission, and furthermore when ''YES'' is the case, the asynchronous injection quantity is decreased to same extent and thereby an injection valve 26 is driven.
