Title: Automatic transmission and engine control device
Inventor: TAKADA MITSURU
IPC: B60W10/10
Filed: 1990-07-16
Abstract: PURPOSE:To prevent a speed change shock from worsening by prohibiting a switch of opening/closing of the opening/closing valve during a period of speed change by an automatic transmission in an engine in which an opening/ closing valve is provided within any of plural number of intake air passages formed for one cylinder. CONSTITUTION:Plural number of intake air passages are provided for one cylinder and an opening/closing value 1 is installed in any of the intake air passages. A torque is made to be changed discontinuously by switching the opening/closing condition of an opening/closing valve 1. For example, in a lean burn engine E provided with a swirl control valve, a detection means 2 is set for the purpose of a practice of speed change by an automatic transmission A. The detection means 2, for example, is designed to detect a practice of speed change on the basis of such signals as the car velocity V, the opening degree TA of throttle, or the rotation number Nt of turbine, or the like so as to input the output signal in the opening/closing prohibiting means 3. When a signal of practice of sped change from the detective means 2 through the opening/closing prohibiting means 3 is received, a switch of the opening/closing condition of the opening/closing valve 1 is prohibited.

Title: Data retrieving method
Inventor: KUSHIDA TOSHIO
IPC: G06F17/30
Filed: 1987-07-29
Abstract: PURPOSE:To speed up the data retrieving by registering data after adding a specific code to a port serving as a key in the data. CONSTITUTION:A data storing memory 5 consists of an NTEXT which manages the number of stored data and a data TEXT. Each TEXT is constituted of an LEN which manages the data length and the actual data DATA. The DATA contains the underline codes added to the parts equivalent to the keys. In such a constitution, an extra key field is not required and only the data having the specific codes are compared with keys. Thus the data retrieving speed is increased compared with the matching operation performed for each string. Furthermore the retrieving actions having no relation with keys are never carried out.

Title: Recovering method for valuable metal from copper-tungsten alloy
Inventor: KOBAYASHI SHINICHIROU
IPC: C22B7/00
Filed: 1980-12-27
Abstract: PURPOSE: To separate and recover high purity Cu and W from Cu-W alloy scraps by immersing the scraps in an aqueous hydrochloric acid soln. and blowing gaseous chlorine into the soln.  
     CONSTITUTION: Waste of a Cu-W alloy contg. 20W70% W or scraps of such as alloy discharged from a manufacturing process are immersed in hydrochloric acid having 1W12N concn., and gaseous chlorine is blown into the acid. Part of Cu in the alloy dissolves in the acid and forms CuCl 2 . This CuCl 2  reacts with the remaining Cu in the alloy, dissolves, and becomes CuCl. This CuCl is converted into CuCl 2  by the blown gaseous Cl and dissolves Cu in the alloy as CuCl again. This reaction is repeated to dissolve Cu in a short time, and W is separated and recovered at high purity. Cu in the Cu dissolved soln. is recovered as CuCl 2 .2H 2 O by a crystallization method or as Cu powder by a cementation method.

Title: Peak current holding circuit
Inventor: CHIBA MASAHIKO
IPC: G01R19/04
Filed: 1987-07-29
Abstract: PURPOSE:To obtain a holding circuit which supplies a current with a peak value at all times by holding a base-emitter voltage and a voltage drop across a resistance corresponding to the peak value of the current by a capacitor. CONSTITUTION:A sufficient current is supplied to the base of an npn type transistor (TR) Q1 so that a current to be measured which flows to the TRQ1 is controlled by a phototransistor (PTR) Q0. A TRQ2 and a capacitor C are connected in series to form a capacitor charging circuit connected to a DC power source E. When the collector voltage of the TRQ1 becomes higher than the voltage of the capacitor C, this charging circuit discharges a charging current from the TRQ2 to the capacitor C. The capacitor C is discharged to the bases of the TRs Q1 and Q2 through resistance R1 and R2, a voltage corresponding to the peak value of the current of the TRQ1, i.e. the peak value of the current of the PTRQ0 is held by the capacitor C, and a current flowing to a TRQ3 is held at the peak value of the current flowing to the PTRQ0. The peak current is therefore led out of the collector of the TRQ3.

Abstract: PURPOSE:To ensure the proper aiming, by obtaining a region formed by a gathering of the spots having the luminous intensity higher than that of a prescribed ratio to the highest luminous intensity and supposing that a mass point equivalent to the light volume exists at each spot. CONSTITUTION:An automobile front lamp HL, i.e., a subject of measurement is set opposite exactly to a tester and switched on so that the lamp axis LL passes through the center L0 of a condenser lens. Then a start switch is pushed to start the gathering of data based on a program. A point M of the highest luminous intensity is first decided among these data, and then the spots having the luminous intensity higher than the luminosity obtained by multiplying a prescirbed ratio by the highest luminous intensity are detected to decide a region AR. It is supposed that a mass point equivalent to its light volume exists at each point within the range AR in order to obtain the centroid point. Thus the proper aiming is possible for the front lamp of an automobile.
