Patent JP-H03269278-A (JP)
Title: Integrated circuit
Inventor: HAMA HIROYUKI
IPC: G01R31/28
Filed: 1990-03-19
Abstract: PURPOSE:To reduce waste in assemble by providing a generating circuit of an input signal for a burn-in test which supplies the input signal for the burn-in test to a logic circuit and also by providing an I/O pad for the burn-in test. CONSTITUTION:When a wafer 18 having LSI chips 19 is subjected to a burn-in test in the state of the wafer, I/O pads 20a to 20r which are usually used are put in an open state, since all input terminals are pullel up or down in accordance with functions, and a power supply, ground and burn-in mode signals and a clock input are inputted to an I/O pad 21 for the burn-in test which is formed to be larger a little than the I/O pads 20 usually used, in consideration of the expansion of the wafer 18 due to a high temperature. By inputting the four inputs to the LSI chip 19 in this way, the burn-in test of the LSI chip 19 in the state of the wafer can be realized, and therefore the waste of executing assembly for an imperfect chip is reduced.

Title: Record for adjustment
Inventor: WASHISAWA SHIGEKI
IPC: G11B3/68
Filed: 1979-06-05
Abstract: PURPOSE: To know the accurate amount of distortion in a simple way and without using the costly distortion factor measuring facilities but by using the record for adjustment on which the plural number of high-frequency signals approximate to each other are recorded.  
     CONSTITUTION: The amount of tracing distortion occurring at the record reproducing time is proportional to the velocity amplitude of the record signal and the curvature radius of the stylus tip, and then adversely proportional to the square of the sound groove change which varies in accordance with the shift of the stylus tip on the record disk. In this connection, voltage (v) proportional to the velocity amplitude is extracted first out of the input signal at distortion correcting part 9 to receive the control for the sound groove position signal which is extracted out of the sound groove position detecting part of the stylus tip and at sound groove position control part 14. Then the control amount is set at stylus tip diameter setting part 16 and in accordance with the diameter of the stylus to be used. Correction amount control part 17 gives the control to the above control amount to the optimum value according to the reproducing conditions. The control signal received these processes gives the control to the distortion correction amount of the input distortion signal to be applied to distortion correcting device 18. In such way, the amount of distortion occurring at the reproducing time can be known in a simple way.

Filed: 1988-03-25
Abstract: PURPOSE:To make improvements in accuracy of rotational speed control by taking over this rotational speed control at the rotating electric machine side and performing it when the rotational speed control at the side of a hydraulic machine fails to be done. CONSTITUTION:A deviation Xx between pilot servomotor opening Yx and main servomotor opening Y is expressed as displacement of a main servomotor control valve. When a switch 103, judging a fact that this deviation Xx has entered a range of dead bands -gamma-+gamma operates, namely, if the deviation Xx gets into the dead band, rotational speed control by effective power control at the side of an induction type generator is started by a power compensation controller 102. Thus, the rotational speed control at the generator side is made so as to be usable only when this rotational speed control becomes impossible in substance.

IPC: G06F12/16
Filed: 1990-03-20
Abstract: PURPOSE:To shorten the time required to save data by managing data, of which saving is not required every time, like an application program saved in a non- volatile storage part once to omit unnecessary data saving. CONSTITUTION:Areas (a) and (b) of a semiconductor memory part are set as (R) whose data is not saved, and an area (c) is set as (R/W) whose data is saved. When initial data is written in all areas and a power source is turned off in this state, data in areas (a) to (c) are saved in the non-volatile storage part. When the power source is turned on next, all data are restored, and infor mation of a third state O indicating that data are restored is stored in a state storage means. If the power source is turned off in this state, a save set storage means is referred by information stored in the state storage means to determine whether data should be saved or not. Thus, unnecessary data saving is omitted to shorten the data saving time.

Title: Optical head
Inventor: NISHII KANJI
IPC: G11B7/135
Filed: 1983-04-20
Abstract: PURPOSE:To enable both beam form converting function and optical path converting function of a prism to satisfy the prescribed value respectively, by providing a positioning part to a housing to control an angle formed by the optical axis of a collimator lens and a total reflecting surface of the prism which provided with said surface. CONSTITUTION:A positioning stage part 7 sets the position of the optical path of a lens barrel 2a containing a semiconductor laser 1 and a collimator lens 2. A positioning stage part 8 sets the position of the total reflecting surface of a prism 6. These parts 7 and 8 function to set an angle formed by the positioning surfaces such as LL, SS, etc. equal to a vertical angle theta4 of the prism 6. Therefore the angle formed by the incident optical axis to the prism 6 and the total reflecting surface of the prism 6 is controlled to the angle theta4 by pressing and fixing the total reflecting surface of the prism 6 to the part 8 and at the same time the laser 1 and the barrel 2a to the part 7 respectively. Thus an incident angle theta1 to the incident surface of the prism 6 is set correctly based on angles theta3 and theta4 of the prism 6. Then a beam form converting function of the prism 6 satisfies a prescribed conversion factor, and furthermore the orthogonal performance is also satisfied between an incident optical axis and an output optical axis.

Title: Voltage-frequency converter
Inventor: GAMOU RIYOUJI
IPC: H03K7/06
Filed: 1978-06-12
Abstract: PURPOSE: To make it possible to correct non-linearity by the input resistance of an integrating circuit of LPF and a resistance and also to improve precision, by connecting a resistance in series to the feedback system capacitor of the integrating circuit of a voltage-frequency converter.  
     CONSTITUTION: In series to capacitor C 2 , linearizing resistance R 4  is connected to the feedback side of integrating circuit 4. Without resistance R 4 , integral characteristics shown by dotted lines in the figure are obtained, but R 4  causes an increase in a shorter time by (eOP.R 4 /R 2 ) at the time of switching of switches Sa and Sb, so that the integral process will equivalently be shortened. Since the amplitude of this increase is in proportion to multiplying voltage (eOP) or (eON), characteristics of output frequency (fO) with resistance R 4  are shown in the figure. For the purpose, adequate selections of resistance R 1  of LPF, input resistance R 2  of integrating circuit 4, capacitor C 2 , and resistance R 4  make complemntary possible and frequency outputs proportional to inputs (e i ) and (e v ) can be obtained. Namely, attaching resistance R 4  cancels non-linearity by resistances R 1  and R 2 , thereby making it possible to obtain ideal characteristics.

Title: Signal level display device
Inventor: OKITSU YUKINOBU
IPC: H04B1/08
Filed: 1990-03-19
Abstract: PURPOSE:To obtain this signal level display device with less dispersion for every system by adding a signal mute circuit to the device. CONSTITUTION:The output of a band pass filter 31 is inputted to a signal mute circuit 35. In this case, the signal mute circuit 35 is connected to a CPU 23 and whether the output of the band pass filter 31 passes as it is or cut off to be a fixed DC level signal is selected in the control of the CPU 23. Thus, a reference level signal obtained from the signal mute circuit 35 at the mute mode is an output level when an input to a level detection circuit is truly zero. Thus, the dispersion in the display value for every system depending on the difference between an output level from the reference level signal generating circuit and an output level at zero input of the level detection circuit is suppressed.
