Title: Control device for direct injection spark ignition internal combustion engine
Inventor: MACHIDA KENICHI
IPC: F02B17/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent the divided injection quantity from becoming below the minimum compensation quantity of a fuel injection valve when a two-stage injection (weak stratified combustion) is made including the suction stroke injection for homogeneous combustion and the compression stroke injection for stratified combustion. SOLUTION: When a two-stage injection is instructed, the total injection quantity TI is split into the homogeneous combustion injection quantity TIH injected in a suction stroke and the stratified combustion injection quantity TIS injected in a compression stroke at the split ratio corresponding to the target air-fuel ratio (S21, S22). The injection quantities TIH, TIS after splitting are compared with the minimum compensation quantity MIN (S23-S25).  If one of the injection quantities TIH, TIS is judged to be below the minimum compensation quantity MIN as the result of the comparison, the injection quantity with a smaller split ratio is set to 0, and the injection quantity with a larger split ratio is set to the total injection quantity TI (S26, S27), or the injection quantity with the smaller split ratio is set to the minimum compensation quantity MIN, and the injection quantity with the larger split ratio is set to the remainder subtracted with the minimum compensation quantity MIN from the total injection quantity TI.

IPC: B23K1/08
Filed: 1988-07-12
Abstract: PURPOSE:To remove surely and in a short while Au plating which is conducted on a component lead by immersing, first of all, the component lead which is plated with Au in an Sn dip vessel and performing the first preliminary soldering, thereby performing the second preliminary soldering after immersing it in an In-Sn dip vessel. CONSTITUTION:A component lead 10 which is treated by Au plating 2 is, first of all, immersed in an Sn dip vessel 3 and the first preliminary soldering is performed. Then, the second preliminary soldering is conducted after immersing the above lead in an In-Sn dip vessel 4. In this way, the preliminary soldering is performed by separating its treatment into two stages. On the occasion of the first preliminary soldering, Au plating on the component lead 10 is removed efficiently after being diffused in Sn and an In-Sn layer which has the same composition as that of a bump 16 is formed on the component lead 10 by the second preliminary soldering. The conditions in the case of component mounting are thus remarkably improved.

Title: Cache memory device
Inventor: KINOSHITA TETSURO
IPC: G06F12/10
Filed: 1993-07-14
Abstract: PURPOSE:To prevent the deterioration of the executing speed of a process by referring to the preference level information stored in a tag in a mishit state based on the address of a replacement candidate cache line and the address of a line through which an access is given to a memory. CONSTITUTION:The preference level information showing the priority of line replacement is previously stored in a replacement inhibiting hit of a tag 3 against the address of each line. In a mishit state, a CPU selects the proper one of lines stored in a cache memory 1 and tries to replace this proper line with a line through which an access is given to the memory 1. Under such conditions, a reference level deciding circuit 7 refers to the replacement inhibiting bit of the tag 3 and reads out the preference level information against the address of a replacement candidate cache line and the address of the accessed line respectively. These preference line information undergo the comparison of their priority. Then a replacement inhibiting circuit 9 inhibits such a case where a line of high priority is replaced with a line of low priority.

Abstract: PURPOSE:To realize a high densification of two times substantially without causing a crosstalk, by overwriting magnetically a second bit of information at a prescribed azimuth angle on the same track, with respect to a first bit of information of a magnetic recording medium. CONSTITUTION:Magnetic heads 11, 12 have azimuth angles theta1, theta2 of + or -45 deg. against a line l1 vertical to a relative moving direction A of a tape 13. When the first information is written by the head 11, the information is written mainly by a magnetic particle which has been varied in the same direction as a magnetizing direction B. Subsequently, when the second information is written by the head 12, the information is written mainly by a magnetic particle which has been varied in the same direction as a magnetic field direction C vertical to the direction B. When a reproducing scan is executed on the same track by the head 11, the recording information is reproduced by the magnetic particle being parallel to the magnetizing information is reproduced by the magnetic particle being parallel to the magnetizing information B, and the second information recorded by the magnetic particle vertical to the direction B is accompanied with a large azimuth loss, therefore, it is scarcely reproduced. According to this constitution, two kinds of information can be recorded in the same magnetic surface without causing a crosstalk, can be reproduced satisfactorily, and a high densification of two times can be realized.
