Title: Series resonance type dc-dc converter
Inventor: KAWAKITA KATSUMI
IPC: H02M3/28
Filed: 1988-10-14
Abstract: PURPOSE:To prevent a switching(SW) frequency from changing steeply relative to an input-output variation by connecting a discharging resistor in parallel with a resonance capacitor via switching(SW) element and by turning ON the SW element within the OFF period of an SW circuit at the time of a light load. CONSTITUTION:A discharging resistor 14 is connected in parallel with a resonance capacitor 8 via switching element 15. In the state of a light load, DC output voltage Io tends to decrease while DC output voltage Vout tends to rise. A load discriminator circuit 16 gives ON signal to the element 15 when the DC output voltage Io is under a set current. When the element 15 is closed, the electric charge of the capacitor 8 is discharged through the resistor 14. Therefore, when transistors 2, 2 are turned ON subsequently, the voltage of the capacitor 8 is reduced so that a resonance current decreases and the DC output voltage Vout lowers. Consequently, a frequency control circuit 19 increases a switching frequency fs to adjust an output frequency.

Title: Projection aligner
Inventor: TANIGUCHI TETSUO
IPC: G03F7/207
Filed: 1991-10-08
Abstract: PURPOSE:To expose a pattern on a wafer with a very accurate image formation characteristic by stopping the exposure on the wafer until a variation in an image formation characteristic comes within a specified allowable level when the illumination conditions are changed. CONSTITUTION:In a projection aligner, illumination conditions altering devices (variable diaphragms 8, 32, a variable blind 10, etc.) which change the illumination conditions for a reticle R and an aligner (a main controller 50) which stops the exposure on a wafer W for a specified period of time (i.e., time until a variation in an image formation characteristic comes to a specified level) when the illumination conditions are altered are installed. After stopping the exposure with a change in the illumination conditions, the exposure is started again with the image formation characteristic being controlled under new illumination conditions. By this method, an exact variation in the image formation characteristic can be found out at the time of exposure of a pattern on the wafer and the image formation characteristic can be corrected accurately.

Title: Navigator for vehicle
Inventor: HOSODA KOJI
IPC: B60W30/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To reduce the load of a CPU or the like, enable recognizing the congestion by the number of facing cars, and improve usage by installing a switching means which operates or does not operate the facing car detecting function, in preference to the automatic stoppage function for halting the facing car detecting function at the time of specific running condition. SOLUTION: An automatic stoppage means R1 halts the facing car detecting function when it is detected that a self car is running on, e.g. a high level road, a road having central separation belt, a double track road and a city street. On the other hand, a switching means (manual switch) operates or does not operate the facing car detecting function, in preference to the automatic stoppage function R1. When facing car detection is stopped by the automatic stoppage means R1, the load of a CPU or a computer is reduced. When In preference to the automatic stoppage means R1, the facing car detecting function is compulsorily operated by the switching means, congestion condition can be recognized by the number of facing cars. When facing car detection is unnecessary, the facing car detecting function is turned into the not-operated state, in preference to the automatic stoppage means R1.

Title: Data reading method and data recording method
Inventor: KAJI TOSHIKAZU
IPC: G11B5/02
Filed: 1992-09-30
Abstract: PURPOSE:To prevent errors in reading by obtaining an average value of the speed when the pulse intervals t1, t2 of reading signals are equal to each other and the changing width of the speed through simulations and transferring a medium so as to satisfy t1<t2. CONSTITUTION:Supposing that the transferring speed changes with a constant cycle while the recording density is a parameter, the relationship between an average value of the transferring speed and the changing width of the speed when the pulse intervals t1=t2 is held is obtained through simulations. The curve representing the relationship has a bending point at the center thereof, starting to incline negatively or considerably small from the bending point. When the average value and the changing width of the transferring speed are increased, the inclination becomes positive and large. In the range where the average value of the transferring speed is smaller than at the bending point and the changing width is within an OK zone, the ratio of pulse intervals of reading signals becomes close to that of the magnetization width. If the transferring distance of a recording medium by half the changing cycle of the transferring speed is set to be smaller than or approximately equal to the shortest length of the magnetic or optical change added to the medium in predetermined direction, the erroneous reading due to the change of the transferring speed is prevented.
