摘要:
In a fuel supply system for internal combustion engines, a fuel delivery pipe to which fuel injectors are mounted through respective connectors is connected to a fuel tank through a fuel piping without return piping. At least one of the connectors of the injectors is extended upwardly to open at an upper portion in the delivery pipe. In the event that air or fuel vapor is generated in the fuel supply system, it is gradually introduced into the delivery pipe and rapidly purged with fuel through the extended connectors and the injectors when the injectors inject fuel into an engine. In order to improve engine cranking operation at high temperature condition, fuel injection period is extended so that vapor or air in the fuel is purged through the injectors. The extension of fuel injection period is terminated as soon as the initial explosion in the engine is detected.

At least one of the connectors of the injectors is extended upwardly to open at an upper portion in the delivery pipe. A fuel pipe which is branched off from the fuel piping is provided above the delivery pipe, and the fuel pipe and the delivery pipe are connected with each other by a connecting orifice. The connecting orifice also extends upwardly to open at an upper portion in the fuel pipe. In the event that air or fuel vapor is generated in the fuel supply system, it is accumulated in the fuel pipe and then gradually introduced into the delivery pipe 1 through the connecting orifice, and rapidly purged with fuel through the extended connectors and the injectors when the injectors inject fuel into an engine.

At least one of the connectors of the injectors is extended upwardly to open at an upper portion in the delivery pipe and has a small diameter extension pipe for enhancing sucking in air or vapor in the fuel delivery pipe into the injectors. A fuel pipe which is branched off from the fuel connecting pipe is provided above the delivery pipe, and the fuel pipe and the delivery pipe are connected with each other by a connecting orifice. The connecting orifice also extends upwardly to open at an upper portion in the fuel pipe.

An in-car telephone system of great convenience is provided when switching between a hands-free conversation and a conversation using a handset of a portable telephone (a handset conversation), which has a portable telephone conducting wireless telephone communication and a hands-free unit, being connected to the portable telephone, which outputs a receiving voice from the portable telephone through a speaker arranged in a car and outputs an aural signal input from a microphone arranged in the car to the portable telephone as a transmitting signal. The in-car telephone system includes a connection detector to detect the communicative connection between the portable telephone and the hands-free unit during a handset conversation using a microphone and a speaker included in the portable telephone, and a mode switching device to switch from a handset conversation condition to a hands-free conversation condition using the microphone and the speaker arranged in the hands-free unit when the connection between the portable telephone and the hands-free unit during a handset conversation is detected by the connection detector.

A digital broadcast receiving apparatus for receiving a digital broadcast, includes a freeze determining section and a display control section. The freeze determining section determines whether or not a freeze process should be initiated on a basis of a receiving status of the digital broadcast. The freeze determining section also determines whether or not the free process being performed should be terminated on the basis of a receiving status of the digital broadcast. The display control section initiates the freeze process when the freeze determining section concludes that the freeze process should be initiated. The display control section terminates the freeze process being performed when the freeze determining section concludes that the freeze process being performed should be terminated. The freeze process includes displaying a freeze notification on a screen while changing the freeze notification so that a user recognizes the change of the freeze notification.

A mass spectrometer has an ionizing portion for ionizing a sample, a mass spectrometric portion for subjecting a sample ion to mass separation and detecting the sample ion and a control portion for controlling operation of a total of the apparatus. The mass spectrometer is provided with a colliding portion provided at an ion path until a sample ion generated by the ionizing portion is introduced to amass spectrometric portion and a gas introducing portion for introducing one kind or more of gases selected from two kinds or more of gases into the colliding portion. By carrying out analysis by using the apparatus, highly accurate mass spectrometry can be carried out.
摘要:
While applying a square wave voltage to the ion electrode (21) so that ions already captured in the ion trap (20) do not disperse, the timing of irradiating a laser light for ion generation is controlled in such a manner that ions reach the ion inlet (25) at a predetermined timing of a cycle of the voltage. In the case of a positive ion (cation) for example, the timing of laser light irradiation is adjusted in such a manner that the target ions reach the ion inlet (25) in the low level period of a cycle of the square wave voltage. By injecting ions in addition to the ions already captured in the ion trap (20) in this manner, the amount of ions can be increased, and by performing a mass separation and detection after that, the signal intensity in one mass analysis can be increased. Accordingly, by decreasing the number of repetitions of the mass analysis for summing up mass profiles, the measuring time can be shortened.

There is provided an alkaline battery produced by sealing in an outer package body: a positive mixture containing at least one selected from manganese dioxide and a nickel oxide, a conducting agent, and an alkaline electrolytic solution (A) containing potassium hydroxide; a separator; and a negative mixture containing zinc alloy powder, a gelling agent, and an alkaline electrolytic solution (B) containing potassium hydroxide where a concentration of potassium hydroxide of the alkaline electrolytic solution (A) is 45 wt % or more, and a concentration of potassium hydroxide of the alkaline electrolytic solution (B) is 35 wt % or less. Because of this, an alkaline battery can be provided, which has desirable load characteristics, prevents the generation of gas, prevents a decrease in a storage property due to the reaction with an electrolytic solution, and has heat generation behavior suppressed at a time of occurrence of a short-circuit.
摘要:
A speech section detection apparatus capable of reliably detecting a speech section even for a word containing a glottal stop sound or for a word containing a succession of “s” column sounds or “h” column sounds (sounds in the third column or the sixth column in the Japanese Goju-on Zu syllabary table). A speech signal detected by a microphone is amplified by a line amplifier, and converted by an analog/digital converter into a digital signal which is then stored in a memory. The stored speech signal is fetched into a pitch detector where a speech pitch is extracted by processing the speech signal in time domain. A gate signal generator controls the gate signal based on the speech pitch, and a speech section signal generator controls a speech section signal based on the gate signal. A word can be extracted by segmenting the speech signal stored in the memory in accordance with the speech section signal.
