Patent JP-H0192826-A (JP)
Title: Information input/output device
Inventor: YAMAMOTO TSUNESUKE
IPC: G06F3/041
Filed: 1987-10-02
Abstract: PURPOSE:To reduce the power consumption of a device by using a memory property displaying means for storing display contents even after interrupting the drive of the device as a display means. CONSTITUTION:Coordinates are inputted to an input tablet consisting of an oscillation transmitting plate 8 with an oscillation pen 3 and the input image is displayed on a display device 11' arranged so as to be superposed under the input tablet in accordance with the inputted coordinate information. A device capable of continuously displaying the final display contents after interrupting the drive of the device such as ferroelectric liquid crystal display (FLCD) having memory property is used as the display device 11'. Since said display is used, it is unnecessary to keep a power supply for the whole device at an ON state only for display drive, so that the power consumption can be reduced.

Title: High frequency balance mixer
Inventor: KAWAKAMI TOSHIMASA
IPC: H03D7/02
Filed: 1989-09-26
Abstract: PURPOSE:To reduce the leakage of a local oscillation signal by providing a transformer converting an unbalanced input signal into a balanced signal, 1st and 2nd capacitors connected in series between output terminals of the transformer and whose connecting point receives the local oscillation signal, a mixture circuit connecting to the output terminal pair of the said transformer and a circuit extracting a prescribed intermediate frequency signal from the output of the mixer circuit. CONSTITUTION:When a frequency of a local oscillation signal is sufficiently higher than a frequency of an input signal, the impedance of capacitors 12, 13 is high with respect to the input signal and low with respect to the local oscillation signal. When the capacitance of the capacitors 12, 13 is nearly equal, the local oscillation signal appears at each output terminal of a transformer 10 to an imaginary midpoint (connecting point between capacitors 12, 13) as the signal of the same phase because of the capacitors of the same capacitance. Diodes 5-8 mix the input signal and the local oscillation signal inputted to them respectively. Since the local oscillation signal is of the same phase, the local oscillation signal is cancelled by the transformer 9 and does not appear in the intermediate frequency signal at the output terminal 3.

Title: Fixed connection system for channel
Inventor: MATSUMOTO NAOAKI
IPC: H04Q11/04
Filed: 1983-12-26
Abstract: PURPOSE:To prevent a fixed connection circuit from being disconnected owing to a transient fault by storing data necessary for fixed talking connections in a nonvolatile control means in a time-division digital electronic exchange. CONSTITUTION:Control memory for supplying readout addresses of switching memory 11 consists of volatile control memory 16 and nonvolatile control memory 17. Those read addresses are obtained by the output of address control memory 18. When an exchange makes a fixed connection between, for example, channels of time slots (l) and (k) on a PCM highway, data A and B in the time slots (k) and (l) are written in addresses (k) and (l) of the switching memory 11 in a write period; and an address AA is outputted from the memory 18 with the time slot (k) in a readout period and data B in the address (l) of the memory 11 is outputted to the time slot (k) and connected fixedly. Even when the contents of the memory 16 are rewritten, there is no influence exerted.

Title: Sheet after-treatment device
Inventor: MURAKAMI KOICHI
IPC: B65H45/16
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a sheet after-treatment device capable of precisely loading a sheet discharged on folded paper. SOLUTION: A sheet after-treatment device 203 is constituted of a folding device 204 and a staple/stack device 205. A folding mode selection switch is connected to it, and a user can make selection to discharge folded paper in the case when a sheet is long. In the case when a folding mode is selected, a sheet comparatively long in the carrying direction is applied with folding motion in the inside of the folding device 204, discharged on a bin as an ordinary sheet and loaded.  However, as discharge of the sheet is carried out in a state where the top bin is lowered below an ordinary sheet discharge position, it is possible to avoid a problem that a head end of discharged folded paper strikes a folding part of the previously loaded folded paper at the time of loading it on a bin, runs under it, disturbs matching of the previously loaded paper and prevents precise loading of the discharged folded paper.

IPC: A61B3/10
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To simplify the configuration of an opthalmologic system and to automatically perform precise measurement by exactly detecting an operating distance. SOLUTION: Light flux from a light source 1 for observation is projected on the cornea Ec and two ring images are formed. The image of light flux reflected on the cornea Ec is formed at an imaging device 6 and a ring image Pr is projected on a video monitor 8. Besides, two pieces of light flux alternately turned on from light sources 11a and 11a for matching operating distances are projected on the apex of the cornea Ec and the light flux reflected on the cornea Ec is received by a photoelectric divided sensor 13. An examiner watches the video monitor 8, aligns a pupil image or the ring image Pr while matching it with an alignment mark Ma, watches a split mark Ms, matches the operating distance and depresses a measuring switch later.  A signal processor 14 inputs the signal of the photoelectric divided sensor 13 and when the AC component of that signal is less than a prescribed level, the shape of the cornea Ec is automatically analyzed.

Title: Stimulation of bio-oxidation in ground
Inventor: RICHIYAADO REBAAN REIMONDO
IPC: B09B5/00
Filed: 1985-11-08
Abstract: @ The present invention provides a process in which oxygen and nutrients are effectively supplied to biota for stimulating the biooxidation of a compound within a subterranean formation characterized by introducing an aqueous solution of hydrogen peroxide into the subterranean formation at at least one site, the 24-hour average concentration of the hydrogen peroxide initially introduced being between 0.0001% and 0.1% and increasing the 24-hour average concentration of hydrogen peroxide with time at a rate sufficient to provide a corresponding increase in oxygen available to the biota within the subterranean formation but without providing a toxic environment to the biota, and increasing intermittently the hydrogen peroxide concentration introduced into the formation for a short time sufficiently to be toxic to biota at or closely adjacent to the site of introduction thereof thereby removing the biota and thus increasing the permeability of the formation at or adjacent to the site of hydrogen peroxide introduction.

Title: Magnetic head
Inventor: UEJIMA TOKUO
IPC: G11B21/21
Filed: 1987-10-02
Abstract: PURPOSE:To contrive the improvement of the durability of a magnetic head and/or a magnetic recording disk by bonding a vibration proof plate member to the the surface of a gimbal or a load arm so as to prevent the vibration of the magnetic head when a magnetic recording disk is rotated or stopped. CONSTITUTION:The vibration proofing plate member 4 is bonded to the surface of the gimbal 2 or the load arm 3 of the magnetic head to allow the bonding face to absorb the vibration energy of the magnetic head. It is desired to use a so-called vibration proofing alloy having a high damping performance such as Mg, Fe, Ni, Mn-Cu, Ni-Ti as the vibration proof member. However, even when a metallic material with a low damping performance such as a phosphorus bronze is employed, the plate is bonded at a part of the bonding face by means of spot welding or the like, then two plates are rubbed together at the bonding face to convert the vibration energy into heat energy, thereby preventing the vibration of the magnetic head. Thus, the vibration hardly takes place in case of the rotation or stop of the magnetic recording disk and the durability of the magnetic head and/or magnetic recording disk is improved.
