Title: Exposing device for color photosensitive material
Inventor: HIDACHI AKIO
IPC: G03B27/32
Filed: 1987-07-07
Abstract: PURPOSE:To make it possible to carry out an effective exposure in a simple construction, by arranging the first, second and third multi-lens arrays and red, green and blue filters movably with respect to a photosensitive material between a display unit and the photosensitive material. CONSTITUTION:Light of an image on a display surface 8a is incident from one end of multi-lens arrays 9R, 9G and 9B all over the whole of the horizontal scanning lines. At this time, a red filter 10R, a green filter 10G and a blue filter 10B are provided at the other side of the respective arrays. When the integrally-formed multi-lens arrays 9R, 9G and 9B are moved downwards, red, light of the image, green light of the image and blue light of the image irradiate the same position in the same horizontal scanning line, to complete the irradiation per one screen, bringing about the state of irradiation with colored image light in which are combined red, green and blue. In the manner as above, colored image is exposed on a micro-capsule layer 2 of a sheet 1, and printed through coloring of a color developing paper 3 by the use of the sheet 1.

Title: Cassette tape recorder
Inventor: SHINOHARA ISAO
IPC: G11B15/087
Filed: 1983-09-14
Abstract: PURPOSE:To ensure the stable drive of a magnetic tape when a tape position is detected by using a tape guide which interlocks a magnetic head. CONSTITUTION:When the continuous actions of a play solenoid are released in a forward reproduction mode, a control shaft 46a of a control plate 30 controls a control hole 24a of a head substrate 24. Thus a magnetic head 25 has a shallow touch with a magnetic tape 76 with a magnetic head 26 moved back. Then a tape guide 26a controls the driving position of the tape 76. The tape position is detected in a forward revolution mode by revolving a reel drive disk 12 at a high speed and driving the tape 76 at a high speed. When the tape driving position is detected in a reverse mode, the head 25 is moved back. Then a tape guide 25a controls the driving position of the tape 76. Thus the tape driving position is stabilized and the tape is taken up stably.

Title: Switching-type power source
Inventor: KOMATSU AKIYUKI
IPC: H02M3/28
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To suppress the variation of load power when starting the control at low load power by detecting a peak current flowing in an output transformer, and performing the control of lowering a switching frequency, when a load power is not larger than a specified level. SOLUTION: The operating frequency of the frequency of a frequency-variable oscillation circuit 8 is determined by an oscillating capacitor 14, a minimum frequency determining resistor 11, and a frequency controlling resistor 12. When a load power is lower than the critical current, the frequency is lowered by a signal detected with a load current detecting circuit 13. The operating frequency is determined by a current flowing in the frequency control resistor 12 and controlled to a frequency not become higher than a specified frequency. The frequency-variable oscillation circuit 8 operates the load power detecting circuit 13, and restricts a minimum frequency by the minimum frequency determining resistor 11, under control not larger than the critical load power current, and the frequency higher than a specified frequency, even if the frequency is lowered.  If the load power lowers to a level so much that an output voltage becomes higher, even if an oscillation frequency is lowered, a pulse width is controlled and narrowed by a pulse width modulating circuit 10 to stabilize the voltage.

Title: Thin-film resistor
Inventor: NARIZUKA YASUNORI
IPC: H05B3/12
Filed: 1990-06-29
Abstract: PURPOSE:To realize a thin film resistor which is stable with time and is greatly resistant to high-power by using metallic chromium, metallic silicon, chromium silicate, silicon oxide and chromium oxide as essential components. CONSTITUTION:An increase in the resistance is suppressed by forming a chromium silicide at a high temperature for a Cr-Si-based thin-film resistor. A sputtering target to be used as a raw material for the thin film is formed of a chromium silicide and silicon. Chromium and silicon which do not form a silicide suppress a high speed which forms the silicide by heating after the film has been formed. A chromium oxide and a silicon oxide are contained in the thin film. For example, a powder which has mixed chromium disilicide (CrSi2) with silicon (Si) in a desired mixture ratio is used as a raw material, and a uniform target containing CrSi2 and Si is manufactured by using a sintering method. The resistance thin film is formed on a glass-coated ceramic substrate by a DC conventional sputtering method.
