Abstract: PURPOSE: To increase the quantity and flying speed of ink particles by bonding one end of a piezoelectric element to a nozzle plate or a side plate through an elastic member in an ink-jet in which voltage is applied to the piezoelectric element to eject ink in a pressure chamber from a nozzle. CONSTITUTION: In a head part 10a of a print head 1a, an elastic member 19b is bonded between the front end of a piezoelectric element 15a and a nozzle plate 14a, and an elastic member 19a is bonded between the rear end of the piezoelectric element 15a and a side plate 13a. When voltage is applied to the piezoelectric element 15a by a driving signal from a driving circuit 18 based on printing data, the piezoelectric element 15a is deformed to decrease the inside diameter to induce the volume change and pressure increase of a pressure chamber 8a so that ink in the chamber 8a is ejected from a nozzle 9a.  In this process, since both ends of the piezoelectric element 15a are supported by the elastic members 19a, 19b, the deformation is not hindered by the nozzle plate 14a and the side plate 13a so that the electrostriction of the piezoelectric element 15a is effectively utilized for the volume change and the pressure increase.

Title: Peak detection system of magnetic disk device and recording medium format constitution system
Inventor: TAKAGI MASAHIRO
IPC: G11B5/09
Filed: 1990-05-25
Abstract: PURPOSE:To attain the format with efficient medium and to increase the storage capacity by adopting the peak detection in which a slice level in the transient state of an AGC amplifier circuit is taken low. CONSTITUTION:As soon as a write gate signal is turned off, a switching time control circuit 22 is started, which outputs a switching signal to a changeover switch circuit 24 and it is switched 'ON' thereby switching a 1st slice level TH1 outputted from a slice level setting circuit 18 to a lower slice level TH2. Thus, the slice level TH2 equivalent to 0% of an AGC output level in the stable state is set to a peak detection circuit 16 and the peak detection circuit 16 is brought into the state not applying slicing substantially. Thus, the amplitude peak of a reproduction signal from an AGC amplifier circuit 14 inputted to the peak detection circuit 16 reaches the slice level TH1 or over, and the peak pulse is generated effectively from a time when a slice gate signal is reset without being affected by a transient time. Thus, the standby time for peak detection within the transient time is not required and the medium storage capacity is increased.

Title: Air-conditioner
Inventor: TANAKA TETSUYA
IPC: F24F11/02
Filed: 1991-06-07
Abstract: PURPOSE:To preferentially operate a heat pump room heating by providing an inverter for controlling the speed of a revolution of compressor and means for controlling the driving frequency of the compressor. CONSTITUTION:Current sensing means 9 generates a sense signal when the input/output current of an inverter 7 for controlling the speed of revolution of a compressor 1 is larger than a specified value. Inverter control means 10 controls the inverter 7 so as to reduce the driving frequency of the compressor 1 when a sense signal is again received after a specified time is elapsed from when the signal is received. Heater control means 11 stops the energization of an auxiliary heater 12 by the signal. Thus, an energy saving drive in which a heat pump room heating is preferentially operated can be conducted by using the heater 12 while protecting the inverter 7.

Title: Joint for double coil spring
Inventor: NISHI KIICHIRO
IPC: A47C23/04
Filed: 1992-04-27
Abstract: PURPOSE: To provide a joint for double coil springs which can cope with different vibrations and impacts without burdening a weaker spring too much by using a pair of coil springs whose spring constants are different. CONSTITUTION: The joint for double coil springs consists of a small coil spring inside and a large coil spring outside. When the set of springs are burdened, the small coil spring is compressed first. The smaller spring constant is suitable for absorbing and releasing a small burden. If the burden becomes heavy, the small coil spring is pushed downward so that the spring is compressed into the same level of the double coil springs 2B. When the burden becomes heavier, the large coil spring 3B is compressed. The spring constant of the large coil spring is larger and suitable for larger vibration and impact. In this case, the small spring 1B is protected by the joint for double coil springs 2B regardless of the strength of the compression of the large spring.
