Title: Intake port for internal combustion engine
Inventor: KIYOMIYA SHINSUKE
IPC: F02F1/42
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To generate the sufficient magnitude of a vertical swirl flow in a cylinder without decreasing an amount of intake air flowing in a cylinder. SOLUTION: A recessed part 8 is formed in the inner wall surface of an intake port on the exhaust valve side situated downstream from an intake port 5 and a protrusion part 6 is formed on the inner wall surface of the intake port on the exhaust valve side situated downstream from the recessed part 8. Namely, the sectional area of the intake port in the position of the recessed part 8 is increased to a value higher than the sectional area of the intake port situated upper stream from the intake port 5. With this state, by relatively protruding from the inner wall surface of the intake port of an exhaust valve in the position of the protrusion part 6, the decrease of an amount of intake air flowing in the cylinder is prevented from occurring.  Further, drift is generated at intake air in the intake port 5, the intake air is caused to flow in a cylinder through the opening of an intake valve 2a on the opposite side to the exhaust valve 2b and a sufficiently high vertical swirl flow is generated in the cylinder.

Title: Thermal head and its manufacture
Inventor: KASHIWATANI MAKOTO
IPC: B41J2/335
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To enable stable, high image quality heat-sensitive recording with sufficient durability and high reliability for a long time, by providing a protecting film on a heat-generating resistance body which is obtained by alternately forming a layer primarily made of carbon and a layer primarily made of a semimetal or metal. SOLUTION: A glaze (heat-generating element) of a thermal head 66 comprises a glaze layer (heat accumulation layer) 82, a heat-generating resistance body 84 and an electrode 86 formed successively on a substrate 80. The heat-generating resistance body 84 and electrode 86 are covered with a lower protecting film 88 primarily made of ceramic and a multilayer protecting layer 90 on the lower protecting film 88. The multilayer protecting film 90 is formed by alternately forming carbon layers 90a primarily made of carbon and metal layers 90b primarily made of a semimetal or metal. The protecting films 88, 90 are scarcely corroded or abraded, without accompanying a crack or separation due to heat or mechanical impacts, having sufficient durability and exhibiting a high reliability for a long time. Heat-sensitive recording of high image quality can hence be conducted stably for a long time.

Title: Method to dampen track motion
Inventor: EIKU RITSUCHITAA
IPC: F16F15/18
Filed: 1991-04-12
Abstract: PURPOSE: To provide a comparatively inexpensive and simple method by utilizing the concepts of an electric machine and a damping energy, on the bearing damper for giving the damping force to the shaft device of a gas turbine engine. CONSTITUTION: An electromagnetic damping system is utilized to slow down the shaft of a gas turbine. A rotor 18 is mounted on the outer race of a bearing through which the shaft 12 passes. The damper can use a permanent magnet(PM) design with the permanent magnet mounted to the rotor. Alternately, the rotor and stator 20 may be designed to operate upon a switched reluctance motor(SRM) design. Instead of installing the rotor to the outer race, the rotor can be installed directly to the gas turbine shaft. In this case, the rotor and a corresponding stator serve both as a damper and also as a generator providing the effective electric generation function from the gas turbine shaft.

Title: Delaying circuit
Inventor: TANAKA SADAAKI
IPC: H04N5/208
Filed: 1981-07-09
Abstract: PURPOSE:To obtain two types of delayed output signals by means of a single delay line, by using a pair of modulating means that perform the right-angled biaxial modulation with the carrier waves having the phases different by 90 deg. from each other, a signal synthesizing means, a delaying means and a pair of demodulating means respectively. CONSTITUTION:The 1st amplitude modulator 43A modulates an input signal Sin by using the signal supplied from an oscillator 41 as a carrier wave. The 2nd amplitude modulator 43B modulates the output of the 1st signal demodulator 46A by using the signal obtained while giving a 90 deg. phase shift to the output of the oscillator 41 as a carrier wave. The outputs of the modulators 43A and 43B are added and synthesized together by a signal adder 44 and then demodulated by the 1st and 2nd demodulators 46A and 46B via a delaying line 45. The demodulator 46A delivers a delayed signal to the signal Sin by using the output of the oscillator 41 directly as a synchronizing signal. While the demodulator 46B delivers a signal having a double delay by using the signal obtained while giving a 90 deg. phase shift to the output of the oscillator 41 as a synchronizing signal.

IPC: B65H37/04
Filed: 1990-04-25
Abstract: PURPOSE:To enhance productivity of image formation by automatically eliminating a sheet by a sheet eliminating means when the sheet is contained in a sheet classification means and the time set beforehand elapses. CONSTITUTION:In a non stapling mode, when the execution of the next job is possible with the number of empty sheet containing bins of a finisher 11, that is the number of bins not utilized in the non stapling mode, the non stapling mode is carried out. At this time, in the non stapling mode, it is set so that the sheet exists over the sheet containing bin 57 of the finisher 11 for a fixed period of time after the job is finished. This is a period set by an operator so that he/she can extract the sheet from the sheet containing bin 57. However, if the sheet is left on the sheet containing bin 57 for more than the fixed time, since the execution of the next job is delayed, the sheets are stapled after a fixed time elapses, fed to a stacking tray 67, and the sheet containing bin 57 is made to be an empty state, and the state where the next job can be carried out is created. Thus, the productivity is enhanced.

Title: Level shift circuit
Inventor: MATSUYAMA TOSHIYUKI
IPC: H03K5/003
Filed: 1985-05-20
Abstract: PURPOSE:To expand the operating range by applying an input signal to a differential amplifier via a constant voltage element. CONSTITUTION:A collector of a transistor (TR) Q3 is connected to a power supply Vcc and the emitter is connected to common via a constant current source I3. Thus, a voltage being the subtraction of a voltage fed to the base from a base-emitter voltage is generated at the emitter of the TR Q3. Since the emitter of the TR Q3 is connected to a non-inverting input of a differential amplifier A1, a brakedown voltage of a TR Q1 is fed from the input to the non-inverting voltage and a voltage being the subtraction of a voltage of the emitter-base voltage of the TRs Q2, Q3 and the voltage lowered by a resistor R is applied. On the other hand, since a power supply VR whose negative electrode is connected to common is given to the inverting input of the differential amplifier A1, the value being the subtraction of the VR from the voltage fed to the non-inverting input is amplified and outputted. Thus, the operating range of the output voltage of the differential amplifier is set widely.
