Title: Constant speed travelling device for automobile
Inventor: NAKANO SHIGERU
IPC: B60K31/04
Filed: 1987-08-17
Abstract: PURPOSE:To surely release the constant speed travelling even if a microcomputer operates recklessly by driving an actuator so that a throttle valve is sharply closed by receiving the signal of a cancellation switch. CONSTITUTION:The first constant speed travelling releasing means 7 receives the signal of a cancellation switch 10 operated by the operation of a brake pedal or clutch and releases the constant speed travelling. The second constant speed travelling releasing means 8 is positioned outside a microcomputer, separated from the first constant speed travelling releasing means 7. A throttle valve closing signal output means 9 receives a cancellation signal and drives an actuator 11 so as to sharply close a throttle valve. When the constant speed travelling is not released, the actuator 11 adjusts the opening degree of the throttle valve 12 by the pulse signals outputted from a pulse output means 6.

Title: Sheet feed device and sheet feed method for image forming device
Inventor: NAKAZATO YASUFUMI
IPC: B65H5/06
Filed: 1992-07-30
Abstract: PURPOSE:To synchronize a sheet with an image forming action at the necessary and minimum sheet interval to surely and precisely perform continuous paper feeding. CONSTITUTION:When a number of sheets P are required to be fed in a unit time, a first paper feed passage 32 is used for synchronization with an image forming action by means of a first sychronizing means 31 and then a sheet P is carried at a higher carrying speed than that of an image forming part 30 so as to reduce an interval to a precdeding sheet. The sheet is carried as it is without taking synchronizing action by a second synchronizing means 34, and efficient image forming is performed. When a special sheet such as a postcard and envelope is fed, a second paper feed passage 33 is used, immediately after taking synchronization by the second synchronizing means 34, the sheet is carried to the image forming part 30, and higher carrying accuracy is obtained in comparison to the case in which the first paper feed passage 32 longer in carrying distance after synchronization is used.

Title: Oscillating circuit
Inventor: IKENO HITOSHI
IPC: H03B5/32
Filed: 1984-09-28
Abstract: PURPOSE:To prevent the degradation of characteristics of an oscillator by constituting an input-side load capacity and an output-side load capacity with input-side and output-side fixed capacitor parts and variable capacitor parts and removing a conductor layer of variable capacitor parts at least to adjust the oscillated frequency. CONSTITUTION:In case of adjustment of the oscillated frequency of a crystal oscillator, a conductor layer 26 appearing in a through hole 27a of a top dielectric layer 27 is removed by the sand blast method or the like to reduce capacity values of input-side and output-side variable capacitors 14 and 15 of the oscillating circuit. The difference between capacity values in the input side and the output side is maximum 3PF though a nozzle (omitted in the figure) of a sand blast device is moved from one end side to the other of the through hole 27a, and the difference between said capacity values is reduced if the nozzle is moved minutely to the right and the left from the center. Since the difference between capacity values in the input side and the output side of the oscillating circuit is reduced in this manner, the power source voltage frequency characteristic of the crystal oscillator is improved.

Title: Time-of-flight mass spectrometer
Inventor: NUKINA YOSHIHIRO
IPC: H01J49/06
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To maintain the convergence property relative to spatial expansion of ions in an ion reservoir in the optical axis direction, even in the case of using a triple-convergence spectral system, and to improve the ion yield. SOLUTION: An ion beam emitted from an outside ion source 1 is regulated by a beam regulation slit 2 and introduced into an ion reservoir 3, and expanded in the ion reservoir 3 in the optical axis direction (z-axis direction) with a range of r0. The ion beam in the ion reservoir 3 is pushed out in the optical axis direction by a voltage pulse V2 in this state. The expansion of the pushed- out ion beam is once time-focused on certain point (or a line) by a two-stage acceleration part 9, and a lag (aberration) of a flight time produced by the expansion of the ion beam is cancelled. Afterwards, the time-focused ion beam is space-focused by a triple-convergence TOFMS spectral part 7 in two directions (x, y-axis) directions) rectangular with the optical axis direction, and eventually space focusing in the x, y, z-axis direction is attained.  Hereby, an ion yield of a time-of-flight mass spectrometer is improved and a resolution is raised.

Title: Production of turbine type vane wheel
Inventor: SAITOU HIDEFUMI
IPC: F01D5/14
Filed: 1983-10-31
Abstract: PURPOSE:To produce an extra-small-sized turbine type vane wheel having a small flow passage area with high accuracy and high efficiency by irradiating a powerful laser beam to a blank material from the radial direction thereof and chipping away the required part of the turbine flow passage by the laser energy. CONSTITUTION:The blank material 1 for the turbine vane wheel having a shaft part 3 at one end, a small-diameter part 4 at the other end and a large-diameter part in the mid-way thereof is rotated around the axial center in an arrow (a) direction. The laser beam B is intermittently and impulsively irradiated to the outside peripheral surface 6 thereof to pierce the turbine flow passage in a manner that the vane part remains in the prescribed part. The extra-small-sized turbine type vane wheel which is integrally formed with blades and shroud and is provided with the turbine flow passage processed to high accuracy is thus obtd. Processing of the flow passage to the shape which is wider toward the inside is made possible without increasing the area of an aperture 7 by irradiating the laser beam B at the changed (b) incident angle. The burn of the material 1 is preferably prevented by inserting a glass rod 9 having a recessed surface part 9a into the shaft hole 5 of the turbine wheel and leading the penetrated laser beam to the outside.
