Title: Life control system for magnetic tape medium
Inventor: UCHIYAMA TOSHIAKI
IPC: G11B15/02
Filed: 1989-04-21
Abstract: PURPOSE:To perform more accurate life control nearly without requiring operator's man-hours by counting the number of times of loading of a magnetic tape medium on a magnetic tape driving part and indicating that the number of times of loading reaches a specific number. CONSTITUTION:A reference frequency storage circuit 401 is stored with the reference frequency of loading of the magnetic tape medium 101 and a loading frequency recording circuit 202 counts how many times the magnetic tape medi um 101 is loaded on the magnetic tape medium driving part 100 and records it on the magnetic tape medium 101. Then a decision circuit 201 decides whether or not the number of times of loading recorded on the magnetic tape medium 101 is equal to the reference frequency of loading stored in the reference fre quency storage circuit 401 and when it is decided that the number of times of loading reaches the reference frequency, an indicator lamp 501 indicates that the number of times of loading reaches the reference frequency. Consequent ly, the life period can accurately be controlled almost without requiring operator's man-hours.

IPC: H01L21/82
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To enable a higher-speed circuit operation by increasing ratio of usage of higher level wiring layers for longer wiring by allocating output pins of cells with high driving capacity, i.e., cells which drive longer wire nodes to higher level wiring layers. SOLUTION: At the time of logic design, a cell 102 of high driving capacity is allocated for driving a long distance wiring. A wiring layer of upper level than a wiring layer of a cell 101 with a low driving capacity is allocated as a wiring layer for an output pin of the cell 102 with a high driving capacity. In this way, the ratio of usage of the upper level wiring for a long distance wiring at the time of wiring arrangement is increased and the operation speed is increased.

Title: Sliding-door fixedly holding device in sliding door type box body
Inventor: OCHIAI YOSHIJI
IPC: E06B1/70
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent the unnecessary opening of a sliding door closed once, and to manufacture a sliding-door fixedly holding device simply at low cost by forming a recess, into which a sash sheave is dropped, at a place, where the sash sheave is placed at the time of the closing of the sliding door on the top face of a rail. SOLUTION: When a sliding door 4 under an open state is closed, sash sheaves 10, 11, 12 are placed on the inner side faces, gently inclined sections 13a, 14a, 15a, of recesses 13, 14, 15 when the right side end of the sliding door 4 is abutted against the side frame of a box body 1. Consequently, the sash sheaves 10, 11, 12 are fitted into the recesses 13, 14, 15 even when the sliding door 4 is closed at high speed or even when the box body 1 is rocked. Since the sash sheaves 10, 11, 12 are put on the gently inclined sections 13a, 14a, 15a, the sliding door travels to the left and is not opened. When the sliding door 4 is opened, the sliding door 4 is drawn slightly to the left side, each sash sheave is slipped off from the recesses, and the sliding door 4 is pulled to the left.  Since the residual two sash sheaves are placed on a rail 3a when the sliding door 4 is passed on the recess 14 at that time, the sliding door 4 is passed smoothly. Likewise, the sliding door 4 is passed smoothly on the recess 15 when the sliding door 4 is further moved to the left side. Accordingly, the sliding- door fixing holding device can be manufactured easily at low cost.

IPC: E02F9/22
Filed: 1989-04-21
Abstract: PURPOSE:To facilitate switching operation from a running mode to a work mode by switching each selector valve to the work mode controlling first and second oil chambers, independent of each other, of a boom elevation cylinder, in the case of performing crane work after running. CONSTITUTION:In the case of performing crane work after running, when a mode selector switch is placed in a work mode, each selector valve 41, 42, 44 is returned to a position (c), (e), (g), opening a main pilot check valve 43, changing oil paths 35, 32 into an open circuit from a closed circuit during running, placing pressure oil chambers 51, 52 of a cylinder 50 independent of each other while connecting oil paths 54, 34 to communicate releasing a pressure of an accumulator 54 to a tank 24 via a throttle 301 in a direction control valve 30. Accordingly, even when boom lift operation is performed just after the mode is selected, the cylinder 50 is prevented from working as a ram cylinder and normally actuated by operating the direction control valve 30. Thus, switching operation from the running mode to the work mode can be facilitated.

IPC: H04B10/572
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent the breakdown or band deterioration of an valance photodiode by providing a bias limiter circuit for limiting the upper and lower limits of the bias voltage of this diode. SOLUTION: The level of a signal detected by a level detector circuit 40 is compared with a preset reference value in a control circuit 50 and inputted to a high voltage generator circuit 60 as an amplified error signal which is limited not so as exceed an upper or lower set values VH and VL of a preset bias voltage. As the result neither over-or under-bias voltage is fed to an avalanche photodiode(APD) 10. The limited amplified error signal controls the high voltage circuit 60 to control the current amplification factor of this diode 10 so that the output of a current-voltage converter-amplifier 20 is held const. despite the input signal level variation. Thus it is possible to prevent the breakdown of the element, band deterioration and waveform deterioration.

The hard film 20 is laminated at least up to the thickness to perfectly cover the magnetic pole 18. The hard film 20 is laminated at least up to the thickness to perfectly cover the magnetic pole 18. An etching protection film 24 is formed on the surface of the element plate 10 where the hard film 20 is formed at least up to the thickness to almost perfectly cover the projection 20a of the hard film 20. When the etching is executed to the element plate 10, both the etching protection film 24 and the projection 20a of the hard film 20 are at last etched. Next, an etching protection film 24 is formed again at the surface of the hard film 20 where the height of the projection 20a becomes L2 and it is then etched.  Such formation and etching of the etching protection film 24 are repeated.

Abstract: PURPOSE: To prevent the service life of a motor from becoming shorter by preventing a brush from cutting a commutator with a simple structure. CONSTITUTION: A small-sized motor is incorporated with a rotor 3 which is rotated on the inside of permanent magnets 9 fixed to the internal surface of a frame 1. A plurality of sets of iron cores 10 wound with windings 8 and commutators 5 insulated from a rotating shaft 4 are fixed to the rotor 3. A brush 6 is electrically connected to the commutators 5 in slidable states to energize the windings 8.

Title: Measuring instrument for belt tensile force
Inventor: KANAYAMA HITOSHI
IPC: G01L5/04
Filed: 1985-05-17
Abstract: PURPOSE:To improve measuring accuracy of the belt tensile force by holding a belt from both sides and bending the belt by a fixed amount and measuring the bending load at this time. CONSTITUTION:When a head 18 of the upper end of a center rod 1 is pushed in an S direction, a sensor part 25 advances in the S direction by a distance which the head 18 is pushed. A spring 11 is pressed by the advance and a guide 3 advances in the S direction by a distance which a spring 12 is contracted. As the result, the tip 19 of the sensor part 25 advances more by the difference of the contracted distance between the springs 11 and 12 than the tip 20 of the lower holder 8. Here, when the belt 7 is held between the lower holder 8 and the upper holder 10, and the force added to the head 18 is relaxed gradually, the tip 19 of the sensor part is further moved upward and the tip 19 bends the belt 7 upward. At this time, a bending amount of the belt 7 is kept at a fixed value. The bending load weighed on the belt at this time is received by a load sensor and the belt tensile force can be measured with good accuracy.
