Title: Loop cain controller
Inventor: ABE MASAYOSHI
IPC: G11B7/09
Filed: 1987-05-15
Abstract: PURPOSE:To control a loop gain at a fixed level with no error by detecting differentially the detecting signal that detected the value of a resonance peak component of the loop characteristics and other detecting signals other than said one. CONSTITUTION:A loop gain control type tracking controller consists of tracking signal detecting elements 1 and 2, amplifiers 5 and 6, a differential amplifier 7,a variable amplifier 8, a phase compensating circuit 9, and a drive amplifier 10. A pickup part 11 is driven by the tracking signal. Furthermore a band pass filter 12 is added to detect the loop characteristics out of the output of the amplifier 7 together with an amplifier/detector 13 which amplifies and detects the signal detected by the band pass filter 12, a voltage comparator 14 and the reference voltage 15. At the same time, a low-pass filter 16 is also provided together with an amplifier/detector 17, and a differential amplifier 18. then a detecting signal having a frequency near the resonance value is differentially detected together with the detecting signals of frequencies other than said one. Thus it is possible to compensate the loop gain at a fixed level with no error even though the gain changes before a detecting point.

Title: Ink jet printer head
Inventor: SOROE KAZUNORI
IPC: B41J2/045
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To enhance the driving characteristics by making a diaphragm for applying a pressure to each ink chamber of a conductive inorganic material, bonding a piezoelectric element to the diaphragm and forming a driving electrode on the piezoelectric element. SOLUTION: A piezoelectric element 3 is bonded directly to the outside of a diaphragm 21 corresponding to each ink chamber 1 and a driving electrode 4 is formed thereon. Since the diaphragm 21 is made of a conductive inorganic material (volume resistivity: 1×10<-1> Ω.cm or below), it can also serve as a lower electrode. More specifically, when a constant voltage is applied to the diaphragm 21 and a diving voltage is applied to the driving electrode 4 on each piezoelectric element 3, the piezoelectric element 3 deforms to bend the diaphragm 21. Consequently, pressure in the ink chamber 1 increases to jet the ink through a jet port 6. Since the piezoelectric element 3 is bonded directly to the diaphragm 21, deformation of the piezoelectric element 3 can be transmitted well to the diaphragm 21 thus obtaining good driving characteristics.

Abstract: PURPOSE:To aim at the promotion of low cost and miniaturization by detecting abnormal voltage to be generated at time of abnormal lighting of a discharge lamp, from both ends of a switching device, and installing a lamp abnormal time protection network which controls the lamp to come into a state of being turned off. CONSTITUTION:There are provided with a fluorescent lamp 2 to be energized from an AC power source 1, a switching device 3 controlling on-off of the lamp and a lamp abnormal time protection network 4 controlling the lamp to its turn-off state at time of abnormal voltage detection. And, abnormal voltage to be generated at time of abnormal lighting in the discharge lamp 2 is detected from both ends of the switching device 3 parallelly installed with the discharge lamp 2 whereby lamp 2 is controlled to the turn-off state. Consequently, the discharge lamp 2 can be made into the turn-off state at time of the abnormal lighting while reducing the number of parts items of the lamp abnormal time protection network 4. With this constitution, the promotion of low cost and miniaturization in the lamp abnormal time protection network is made attainable.

IPC: F25D21/06
Filed: 1988-05-17
Abstract: PURPOSE:To restrain the temperature rise of an air curtain even during defrosting in either one of both evaporators, by a method wherein a passage is divided into two divisions of a high-pressure area and a low-pressure area while the high-pressure area is divided into an inside passage and an outside passage to branch air stream, passing through a second evaporator, into the inside passage and the outside passage at all times. CONSTITUTION:An air circulating passage 9 is divided into two parts of a high-pressure area and a low-pressure area by a fan case equipped with ventilating fans 8A, 8B. A second evaporator 14 is provided in the low-pressure area between the fan case and a suction port 11. A partitioning plate 12 between an inside passage 9A and an outside passage 9B, a first evaporator 13 arranged in the inside passage and a defrosting device 15 for frost adhered to the first evaporator 13 are provided in the high-pressure area between the fan case and blow-off ports 10A, 10B. Both of the evaporators are constituted so as to effect cooling operation and defrosting operation alternately. According to this method, cold air stream in the outside passage is blown off to form a low-temperature outer layer air curtain without being affected by the heat of the defrosting device and restrains the temperature rise of an inner layer air curtain as well as the invasion of atmosphere. A part of moisture in the cold air stream of the second evaporator upon off-cycle defrosting flows into the outside passage whereby the amount of frosting per unit time of the first evaporator during cooling may be reduced.

Title: Image encoding system, image decoding system, information storage medium and electronic equipment
Inventor: IZUMIDA MASAMICHI
IPC: H04N19/423
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To insert additional data to image data while reducing the degradation of image quality by inserting the additional data to a high frequency component of an orthogonal transformation coefficient when the orthogonal transformation coefficient obtained by orthogonal transformation is quantized. SOLUTION: An additional data is inserted for the least significant bit of the high frequency component of a DCT coefficient by a display part E4. Thus, change of image quality is not affected, for example, by writing of zero (the additional data) when the least significant bit of original image data is zero and writing of 1 (the additional data) when the least significant bit is 1. Namely, only when writing of 1 when the least significant bit of the original image data is zero and the writing of zero when the least significant bit is 1, deviation is generated in a value of the least significant bit. The least significant bit is the one of the high frequency component of color difference data which is inconspicuous to human eyes. Therefore, possibility that the least significant bit is sensed is hardly exit even when the additional data is inserted into it.

Title: Stop position detector for unattended inductive car
Inventor: KANAZAWA JIYUNPEI
IPC: G05D1/02
Filed: 1980-08-29
Abstract: PURPOSE:To obtain stop position detection with high accuracy, by using that a lead bar is in opposite magnetism and opened with repulsion when a horizontal lead switch comes above a permanent magnet. CONSTITUTION:Signals from two reed switches combined almost in T shape are ANDed to detect the stop position. For example, horizontal and vertical lead  switches 2, 3 are connected between the base of a transistor 4 and ground and the  base and the emitter respectively. Thus, when a mobile body approaches a permanent magnet, the lead switch 2 of horizontal direction is closed and the vertical  reed switch 3 is closed. When the horizontal lead switch 2 comes just over the permanent magnet, since the horizontal lead switch 2 is opened, the base current flows  to the transistor 4, allowing to detect the position.
