Title: Electronic control type fuel injector for internal combustion engine
Inventor: WATANABE YUKIHIRO
IPC: F02D41/34
Filed: 1987-02-28
Abstract: PURPOSE:To prevent the overlap of both synchronous and asynchronous fuel injection periods by delaying the period of injection which is requested later when the synchronous injection overlaps the asynchronous injection. CONSTITUTION:The timing and amount of injection of a fuel injection valve 2 are controlled by means of a control circuit 1 to which are inputted signals from various kinds of sensor such as a throttle sensor 3. A synchronous injection which is synchronized with the rotation of an engine is performed in the normal operation. On the other hand, when an accerelation condition is detected from a signal of a throttle sensor or the like, a demand on a synchronous fuel injection is generated. When the synchronous injection period overlaps the asynchronous injection period, the injection period which is demanded later is delayed in order that both periods do not overlap each other. The overlap of both injection periods is thus prevented without any increase of memory capacity.

Title: Atomic oscillator
Inventor: KUDOME KENJI
IPC: H01S1/00
Filed: 1995-03-06
Abstract: PURPOSE: To provide an atomic oscillator which controls or corrects influences of magnetic field change applied to atoms, and which enhances frequency long- termed stability. CONSTITUTION: Output frequency of a voltage control crystal oscillator 10 is modulated by a frequency modulator 12 using an output of a modulation oscillator 11 and switched to microwaves by a frequency synthesizer 13 to be input into a hollow resonator 4. When frequency of microwaves coincides with resonance frequency of Cs atoms, an output current of an ionizing detector 6 becomes the maximum. The output current is amplified by a signal amplifier 14 and synchronous detecting is performed by a synchronous detector 15 to obtain frequency discriminating signals. As these frequency discriminating signals become 0, the voltage control crystal oscillator 10 is controlled by a voltage control circuit 16. At this time, an applied magnetic field to Cs beams 2 is measured by a magnetic field sensor 17 and a magnetic field measurer 18.  When the applied magnetic field is changed by influences such as an external magnetic field etc., a current control circuit 19 controls a magnetic field generating current source 7 to hold the applied magnetic field to be a constant value.

Title: Manufacture of buried type semiconductor laser
Inventor: FURUYAMA HIDETO
IPC: H01S5/24
Filed: 1982-03-25
Abstract: PURPOSE:To provide by a normal crystal growing method a relatively readily thin active region by employing two adjacent blade-shaped mesas instead of the provision of the groove on a semiconductor substrate. CONSTITUTION:The growth is accelerated at the mesa side surface (111) and the growing solution is absorbed to the side surface in the mesa (100) surface having narrow width, and the growing speed of the (100) surface of 0 or negative. When the mesa having narrow width is disposed adjacently, a crystal is not, if the crystal is grown to the top of the mesa, grown. Further, the crystal growing speed between two blade-shaped mesas is later than the case of the buried mesa groove. This is because the growing speed of the other outside of the (111) or (-111) exposed between the two blade-shaped mesas is fast, and the solute in the growing solution is dispersed to stop the fast growing speed between the two mesas. A bias layer or a high resistance layer 6 is formed in the region disposed between the mesas, thereby narrowing the current. According to this structure, a thin InGaAsP active layer 3 is formed with good controllability on the InP substrate 1, thereby obtaining a preferable buried type laser device.
