Patent JP-H01114091-A (JP)
Title: Semiconductor laser driving circuit
Inventor: WADA AKIRA
IPC: G11B7/125
Filed: 1987-10-28
Abstract: PURPOSE:To control a maximum current in accordance with an ambient temperature by a method wherein a thermistat is inserted between the collector of a 1st transistor constituting a voltage-current converting circuit and the base of a 2nd transistor constituting a current mirror circuit. CONSTITUTION:When an input voltage V is applied to an input termind 1, a current i1 which is increased proportionally to the input voltage is applied to the collector of a 1st transistor Q1. When the transistor Q1 is saturated, the current i1 reaches the maximum input current and the current increase is stopped. The maximum current is varied in accordance with the resistance of a thermistor TH which is varied by an ambient temperature. On the other hand, as the output current i2 of a 2nd transistor Q2 is proportional to the output current i1, it is also influenced by the thermistor TH. The resistance of the thermistor shows negative characteristics against the ambient temperature, the higher the temperature, the larger the maximum current. With this constitution, the maximum current for driving a semiconductor laser 4 can be satisfactorily predetermined in accordance with the ambient temperature.

Title: Expansion valve
Inventor: HIROTA HISATOSHI
IPC: F25B41/06
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To optionally stop the flow rate of a high pressure refrigerant to be sent into an evaporator by providing a contact part to push a rod against an urging force of a spring for full closure when a mobile iron core moves in the direction farther from a valve body with the closing of a power to an electromagnetic solenoid. SOLUTION: When the energization of an electromagnetic coil 51 is stopped, a mobile iron core 53 is made free, the condition under which it will not be attracted to the side of a fixed iron core 52 and a mobile rod 61 for fully opening moves to the side of a valve body 25 by an urging force of a compression coil spring 60 for full cluster to press the valve disc 25 onto a valve seat 24. With the pressing of the valve disc 25 onto the valve seat 24 by the urging force of the compression coil spring 60 for full closure, the valve disc 25 is fully closed regardless of the state of a power element part 30, no refrigerant flows into an evaporator unless the electromagnetic coil 51 is energized. Thus, the flow rate of a high pressure refrigerant to be sent into the evaporator can be stopped optionally with a cost-limited structure.

Title: Photomask
Inventor: YAMADA MASAHIRO
IPC: G03F1/00
Filed: 1987-10-27
Abstract: PURPOSE:To minimize an error at the time of changing a unit from a unit of mil to a unit of mum without increasing the size of a chip by setting the chip sizes of two sides of the outer sides of a rectangular semiconductor device defined on a photomask. CONSTITUTION:When a size unit mil represented in an inch system is converted to the unit of mum in a meter system, a rounding error is generated. For example, in a 4-chip reticule, the photomask is formed by a semiconductor device area 1, a scribe line area 2, and a light shielding body area 3. Assuming the size of a horizontal direction in a rectangle forming the chip as X and that of a vertical direction as Y, relation X=x+a/2, and Y=y+a/2 can be established. In such a case, a coefficient 25.4 exists when the sizes X and Y are converted from the unit of mil of the inch system to the unit of mum of the meter system. Therefore, by setting the sizes X and Y at 5mil unit, a decimal place is eliminated and it goes to an integer, therefore, the rounding error can be reduced.

Title: Manufacture of semiconductor device
Inventor: KANEKO TOSHIAKI
IPC: H01L21/301
Filed: 1987-10-27
Abstract: PURPOSE:To stably produce the shape of a ship with good reproducibility by a method wherein grooves are formed with a scribing line on an array between, and load is applied by pressing an acute-edged tool against the array from below or the reverse side of the scribing line. CONSTITUTION:Grooves 4 are formed with a scribing line 3 on a semiconductor crystal array, on which electrodes 2 are formed after the completion of epitaxial growth, between. After that, the chip formation is done through the application of load by pressing an acute-edged tool 5 against the array from below or the reverse side of the scribing line 3. Due to the action of the grooves on both sides of the scribing line, the crystal surface, which is cloven by applying loaf with the acute-edged tool to the surface of the array on the reverse side of the surface having the scribing line thereon, is kept within the range between the grooves on both sides of the scribing line or does not come outside said range between the grooves during ship formation, even when there are damages, which run in various directions, just below the scribing line. Further, even when the damages extend further during ship formation, the damages gather to positions, which end to the bottoms of the grooves.

Abstract: PROBLEM TO BE SOLVED: To provide a desynchronization detector in a sewing machine capable of improving efficiency in sewing on a common sewing cloth and surely preventing the occurrence of defects in a sewn product attributable to desynchronization by enabling the detection of the desynchronization in the drive of an embroidery frame at a low cost. SOLUTION: During embroidery sewing, both an X-shaft coarse encoder and a Y-shaft coarse encoder detect a pitch that is coarser than the minimum feed pitch of an embroidery frame driven by a stepping motor. Based on the detection, it is examined (S108 and S109) that the variables Px and Py are in the ranges of Xp±L and Yp±L or not, respectively. If the variables Px and Py are out of the range (both S108 and S109 are N), the sewing machine is stopped immediately (S111) and at the same time a warning alarm against desynchronization is displayed (S112).

IPC: G06F3/12
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a printer device in which only one hard disk should be prepared, and only one time of down-load work is required by sharing a hard disk loaded on one printer on a network with the other printers. SOLUTION: At the time of down-loading font data from a computer 10 to printer 2, the down-load operation is executed in the same way as a printer on which a normal hard disk is loaded, and the font data are actually stored in the hard disk of a printer 1. That is, at the time of down-loading the front data to a printer connected with a network, the font data can be down-loaded through the network to a hard disk loaded on a printer on the same network which is recognized as a hard desk directly connected with the printer. Thus, it is necessary to load an expensive hard disk on only one printer, and to perform the time consuming down-load work only one time.

Title: Electric controller for multiphase brushless motor
Inventor: MORI KENNI
IPC: H02P6/06
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacture cost of an electric controller for a multiphase brushless motor. SOLUTION: Magnetic sensors 16a-16c generate magnetic pole signals, which show the electric angles of a rotor by a resolution of π/3, and rotational sensors 16d and 16e generate signals whose levels change each time the electric angles of the rotor change by 2π/216. Then, until the signal level of the magnetic sensor 16a changes, since the start of current application to the three-phase brushless motor, the current application control geared to the electrical angle region of the rotor being inferred, based on the combination of the signal levels of the three magnetic pole sensor is performed, and after the signal level of the magnetic pole sensor 16a changes, the current application control geared to the electrical angle which is inferred based on the electrical angle that the change of the signal level shows and the rotational angle of the rotational angle sensor is performed.  Accordingly, there is no need for strictly performing the positional adjustment of the magnetic pole sensors 16b and 16c other than the magnetic pole sensor 16a, which can reduce the manufacture cost of the device.
