IPC: H05K3/34
Filed: 1994-03-18
Abstract: PURPOSE:To avoid imperfect connection of solder bumps, increase connection strength, increase the number of signal electrodes, enlarge the allowable power consumption of an element, and increase the heat dissipation efficiency of an element. CONSTITUTION:After semiconductor integrated circuit elements 102 wherein power supply electrodes 107 are set larger than signal electrodes 106, and the electrodes of a wiring board 103 are alternately arranged in rows and columns, the signal electrodes 106 and the power supply electrodes 107 are connected with solder bumps (1) 104 and solder bumps (2)105, respectively. The volume of the unit area of the solder bump for the signal electrode as a small electrode is made smaller than that of the power supply electrode as a large electrode. Thereby the heights of the solder bumps of both of the electrodes are made nearly equal after wet-back is performed.

IPC: H04L12/70
Filed: 1991-03-13
Abstract: PURPOSE:To realize the CRC arithmetic operation with a small hardware scale. CONSTITUTION:A CRC arithmetic means 102 executes CRC arithmetic operation to a reception data 101 by using a CRC arithmetic result actual value 103 at a precedence arithmetic operation as an initial value to output the CRC arithmetic result actual value 103. A delay means 104 delays the CRC arithmetic result actual value 103 by a data length of the header part. A CRC arithmetic result introduction means 105 uses the delayed CRC arithmetic result actual value 103 and uses it as an initial value to output the result of arithmetic operation to be possibly obtained if the CRC arithmetic operation were executed to the entire reception data of the header part with the above CRC code added thereto as a CRC arithmetic result derivative value 106. A coincidence detection means 107 compares the CRC arithmetic result actual value 103 with the CRC arithmetic result derivative value 106 to detect an input timing of the header part as the coincident timing of the both.

Title: Method and device for interleave digitizing
Inventor: MINEGISHI ATSUSHI
IPC: H03M1/12
Filed: 1991-02-21
Abstract: PURPOSE:To calibrate a digitize timing of an interleave digitizer accurately. CONSTITUTION:The method is configurated so that a sinusoidal wave whose period is 5nsec is impressed in parallel to 4 sets of digitizers as a calibration signal, 4-phase clocks CK1-CK4 delayed by 1nsec each from a clock CK0 whose period is 4nsec synchronously with the calibration signal are generated and the CK1-CK4 are impressed respectively to each digitizer to digitize the calibration signal. Since one of each output of the 4 sets of the digitizers obtained for one period of the CK0 indicates the result of sampling the zero cross point of the calibration signal, when the result is deviated from zero, the delay of the CK1-CK4 is fine-adjusted to allow the result to indicate zero. Thus, timing calibration with high accuracy is attained.

Title: Controller for idling engine speed
Inventor: MURAMATSU MOTOYASU
IPC: F02D41/26
Filed: 1983-03-25
Abstract: PURPOSE:To prevent the stoppage, too high rotational frequency, etc. of an engine, by calculating a controlled quantity from the density of the air when a learnt value for an idling revolution speed control valve is abnormal. CONSTITUTION:In a controller for the idling engine speed, as shown in the drawing, a controlled quantity for an idling engine speed control valve 22 is stored as a learnt value a1 in a RAM59 to equalize the engine speed to an aimed value. When numerical values are complementary to each other, the learnt value a1 is judged to be normal. When the numerical values are not complementary to each other, the learnt value a1 is judged to be abnormal. The controlled quantity (a) is expressed by using a sum a0+a1 where a0 denotes a predicted quantity which is a function of the cooling water temperature or the like of the engine. During the period of feedback control of the injected quantity of fuel, the final fuel injection time Tau is expressed as Tau=Tb.Fe.Fg.Fx where Tb denotes a basic fuel injection time, Fe a feedback coefficient based on the signal of an O2 sensor, Fg the learnt value, and Fx a compensation coefficient based on a parameter of cooling water temperature or the like.

Title: Lean-burn type gas engine
Inventor: NISHIZAWA HIRONORI
IPC: F02D19/02
Filed: 1990-02-27
Abstract: PURPOSE:To shorten a span of time required for engine starting by interposing a starting mixer between an intercooler in a mixture feeding passage for a combustion chamber and a throttle valve, and installing a starting regulator in a starting fuel gas feeding passage to feed this mixer with fuel gas. CONSTITUTION:An air-fuel mixture blended by a mixer 6 is fed to a combustion chamber 2 via a compressor part 7a of a turbocharger 7, an intercooler 8, a starting mixer 9 and a throttle valve 10, but volume in the combustion chamber mixture passage in this while is large enough, and since air is left behind in this passage, a certain degree of time is required till the mixture is reached to the combustion chamber 2. However, combustion gas is also fed to the mixer 9 by way of a starting fuel gas feeding passage 19, so that the air stayed in the passage 3 and the fuel gas are mixed together by this mixer 9, thus the mixture is fed to the combustion chamber 2, and since volume in the passage 3 lying between the mixer 9 and the combustion chamber 2 is small, the mixture is fed to the combustion chamber 2 at once.

Title: Glow plug and manufacture thereof
Inventor: NASU HIROTETSU
IPC: C23C28/00
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a glow plug having a chromate coating covering the surface of a main metal containing small quantity of hexavalent chromium and excellent in corrosion resistance and heat resistance as compared with a conventional one, and a manufacturing method thereof. SOLUTION: Surface of a main metal is covered with a chromate coating of 0.2-0.5 μm thick where trivalent chromium occupies 95 wt.% or more of chromium component. Since the chromate coating is made thick as compared with conventional trivalent chromium based chromate coating of about 0.1 μm thick, corrosion resistance is enhanced significantly and a sufficient durability against corrosion can be imparted to the main metal. Furthermore, corrosion resistance of the main metal can be sustained sufficiently even in the inherent environment of glow plug susceptible to easy temperature rise and acid attack. Chromate treating bath where a trivalent chromium salt is mixed with a complexing agent for trivalent chromium is preferably employed.
