Title: Check valve unit with oil pressure release function and pump function
Inventor: KIMURA SEIJI
IPC: F15B1/00
Filed: 1995-02-13
Abstract: PURPOSE: To boost an oil pressure again after releasing by installing a plunger member which can increase/decrease the volume of an oil chamber communicated to an actuator in a check valve provided with an operation part which can open the valve from the outside. CONSTITUTION: A check valve 43 is opened by the manual operation of the valve opening operation part 51a of a check valve unit 20 and an oil pressure is released to the oil chamber 62 of a pump mechanism 60 from an actuator port 41a through the check valve 43. Then, a plunger member 63 is moved leftward and oil is filled in the oil chamber 62 by the elastic deformation of a compression spring 64, but as the compression spring 64 is a weak spring for the oil pressure of a prescribed very low pressure, a circuit oil pressure is dropped up to the nearly prescribed very low pressure.  Then, the plunger operation part 63c of a boost operation mechanism 70 is moved pushingly rightward and the oil pressure is supplied to the actuator port 41a from the oil chamber 62 through the check valve 43 and the plunger 63 is stopped when the oil chamber 62 becomes a set low oil pressure and the oil pressure circuit holds the set low oil pressure.

IPC: H04L27/18
Filed: 1986-03-06
Abstract: PURPOSE:To improve an error rate by sending periodically a symbol decreasing the number of modulation bits per baud rate while using a time division multiplex system to form a frame synchronizing signal and using the symbol as a secondary channel. CONSTITUTION:Data of a main channel M-CH is given to a part TM in a frame period T and data of the secondary channel S-CH is given to a part TS. The arrangement of signal points of the data of the main channel shows 256 symbols (=2<8>) and the data of the secondary channel is 16 symbols (=2<4>). The ratio of the symbol (256 values, 8 bits) of the main channel to the symbol (16 values, 4 bits) of the secondary channel is specified, the signal is sent at a prescribed period with multiplexing and the period is used as a frame signal. A correlation detector takes correlation of the symbols over several frames and the frame signal is extracted by checking statistically whether a signal exists at the signal point position of 256 values or the signal point position of 16 values has a signal.

Title: Optical type displacement detector
Inventor: ICHIKAWA SOJI
IPC: G01D5/38
Filed: 1987-03-04
Abstract: PURPOSE:To provide a pitch larger than that of an original detection signal, by multiplying a fundamental pitch by a natural number differing from that for a first grating to obtain a length as the pitch of a second grating. CONSTITUTION:This detector is made up of a main scale 14 (or a reference scale 18) in which a grating 16 (or 20) containing a high frequency component is formed with a grating pitch P (or Q) as length obtained by multiplying a fundamental pitch (r) by a natural number (m) (or n, mnot equal to n), a light receiving element 22 which detects changes in the quantity of illumination light caused by the overlap of the gratings 16 and 20 when the gratings move relatively and the like. The gratings 16 and 20 herein used are bivalent gratings which are formed to include all harmonic components with the ratio of roughly 1:1 between a light transmitting section and a shielding section. Thus, the grating 20 also uses harmonic components to filter harmonic components of the grating 16 thereby achieving optical division with the grating pitch Q of the grating 20 as intact. This enables the setting of the pitch of the grating 20 larger than the pitch (r) of an original detection signal as base.

Title: Bedding using weight
Inventor: AKAOKA NORIO
IPC: A47G9/02
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To increase the contacting degree of bedding, to prevent the shifting of the bedding by turning over in sleep and to reduce a useless space between a body and upper and lower bedclothes by attaching weights to the appropriate positions of a coverlet. SOLUTION: On the strong cloth 2 of an appropriate size as the coverlet capable of sufficiently wrapping shoudlers by appropriately recessing a part where the neck is in contact, many weights 1 of lead or the like of required weight are attached to the appropriate positions mainly near the edge of the cloth excluding the part to be in contact with the neck. When it is covered with a blanket or the other cloth and turned to the coverlet, since the coverlet is brought into close contact with a mattress by the weights 1, the fear of shifting and falling is eliminated at all. Since a useless air amount between the body and the bedding becomes less, warming is quickly performed. Since the shoulders are covered well, even when turning over in the sleep is performed, the air goes out and comes in less, the fear of getting cold is eliminated and sound sleep can be performed.  Since the weights 1 are not brought into direct contact with the body, the fear of getting heavy is not present.

Title: Arithmetic unit
Inventor: ARAI SEIJI
IPC: G06F7/50
Filed: 1986-03-06
Abstract: PURPOSE:To easily discriminate the action of a carry lock-ahead circuit by supplying a carry signal to an arithmetic logical unit to handle the lowest order bit of a higher order digit when a carry lock-ahead signal is outputted regardless of the non-establishment of carry lock-ahead conditions. CONSTITUTION:Suppose that at a carry output node inversion C0 of an arithmetic logic unit 1, '0' appears and at a result output sum of other units 2-4, '1' appears, since carry lock-ahead conditions are established, a carry look- ahead circuit 5 outputs a carry look-ahead signal. As the result, a transfer gate 6 is turned on, and by the inverting signal of the carry look-ahead signal, a transfer gate 8 is turned off. Thus, the carry signal only based upon the carry look-ahead signal is supplied to an arithmetic logical unit 7. On the other hand, when the carry look-ahead signal is outputted by the trouble of a carry look-ahead circuit 5, the transfer gate 8 is turned off, and therefore, the error occurs at the final arithmetic logical arithmetic result and the trouble can be easily discriminated.
