Abstract: A framework registers the entry names of entry interfaces respectively included in modules. The framework acquires operation names (static entries) of operation interfaces included in the module by calling the entry interface based on the entry name. The framework calls the operation interfaces based on the operation names. And the module executes generation of the module itself to be connected to the framework, a process inherent in the module, and deletion of the module itself connected to the framework.

Abstract: A process for preparing indolopyrrolocarbazole derivatives [I] by trating a compound [V] with a base in an inert solvent to prepare a compound [IV], reacting the compound [IV] with a compound [III]to prepare a compound [II], and deblocking the compound [II]; intermediates [II], [III] and [IV]; and a process for preparing compounds [III]: [wherein Y1 is hydrogen, C1-4 alkyl, phenyl, benzyloxymethyl, or aralkyl; R1, R2, R3, R4, R5, and R6 are each independently a hydroxyl-protecting group; R7 and R8 are each independently hydrogen or a hydroxyl-protecting group; and X is an acid molecule]. The above process is a safe and easy industrial process for preparing indolopyrrolocarbazole derivatives [1] useful as antitumor agents.

Abstract: An entire peripheral surface of a port bent portion (5) of a direct intake port (2) has a peripheral side surface portion (11) close to a cylinder axis (10). The peripheral side surface portion (11) provides a projection (12) for deviating intake air current (A) from the peripheral side surface portion (11) toward an opposite peripheral side surface portion (13). Further, the bent portion (5) has a peripheral side surface portion (14) close to an upper end surface (9) of a cylinder chamber (8), which provides a projection (15) for deviating the intake air current (A). This projection (15) turns a direction of the intake air current (A) from a peripheral side surface portion (14) close to the upper end surface (9) of the cylinder chamber (8) toward an opposite peripheral side surface portion (16).

Abstract: A method and apparatus for acquiring a magnetic resonance image representing a surface anatomy of an object, the method comprising the steps of setting a surface coil near the head of a subject, executing a predetermined pulse sequence for selecting magnetic resonance signals from protons inside the head, thereby applying a static magnetic field, gradient magnetic field, and a radio frequency pulse, detecting the magnetic resonance signals from protons by using the surface coil in accordance with the predetermined pulse sequence, reconstructing an image representing the brain surface anatomy of the subject utilizing the detected magnetic resonance signals, and displaying the image in gray scale so that the distribution of the protons is displayed in black level in proportion to the density thereof.

Abstract: In one encoding process of MRI, a pulse sequence by a multi-echo method is executed to acquire first and second MR signals of a predetermined slice. A pulse sequence with a shorter echo time is executed by exciting the slice, thus acquiring a third MR signal. In this case, when an echo time and a repetition time are changed, the first MR signal becomes a signal with an emphasized atomic nuclear density, the second MR signal becomes a signal with an emphasized transverse relaxation time T2, and the third MR signal becomes a signal with an emphasized longitudinal relaxation time T1.

Abstract: A magnetic resonance imaging system comprises a static field generating section, a gradient field applying section, a high-frequency pulse applying section, a sequence control section, a receiving section, and an imaging processing section. The sequence control section includes a first echo excitation section for sequentially applying a 90.degree. pulse and a 180.degree. pulse to the object, thereby generating a first magnetic resonance echo signal, a second echo excitation section for applying a 180.degree.
